[0013] The present invention of Chapter 1 is a mouse for brushing multiple dental positions simultaneously. The present invention relates to the field of dental cleaning devices having pieces, in particular dental cleaning A nicing device, the mouthpiece comprising a body portion provided with at least one recess. at least one recess is lined with a plurality of bristles The recess is bounded by a recess wall that is disposed between the recess and the plurality of bristles. and the recess wall defines a length axis of the arch shape and is spaced apart from the length axis. The dental arch defines a U-shaped cross-sectional shape when viewed transversely, and includes a plurality of disks extending along the dental arch. The present invention relates to a dental cleaning device configured to encompass a dental position. [Background technology]
[0014] [Background Technology in Chapter 1] Cleaning of human and animal teeth is a prerequisite for oral hygiene and internal organ health. For example, there are various dental cleaners, including manual and electric toothbrushes. These typical toothbrushes do not effectively remove plaque. To remove plaque, brush your teeth using the prescribed method for at least two minutes a day. However, the average person does not have enough time to clean their teeth regularly. Do not spend all your time on brushing, but always brush in an effective way. In addition, toothbrushes may be harmful to the disabled, elderly, or children. Brushing your teeth can be difficult because a typical toothbrush This requires precise positioning of the brush bristles on the various surfaces of the teeth. do.
[0015] As is frequently the case in older adults, some or all of the teeth may be missing. If used, cleaning of the gums in these dental locations may still be possible. , is a prerequisite for oral hygiene and internal organ health.
[0016] To clean the teeth and / or gums in these dental locations, There exists a need to automatically brush the teeth and / or gums at these dental locations. There is a need for effective brushing, which reduces the time and effort required. In addition, there is a need to avoid having to carefully manipulate the brush.
[0017] Dental cleaners that include mouthpieces that cover the upper and / or lower dental arches These mouthpieces provide at least one recess. The at least one recess may be of a type including a body portion having a plurality of recesses. The recess is bounded by a recess wall lined with a number of bristles, The bristles extend into the recess from a recess wall, the recess wall having an arcuate longitudinal axis. The tubular member defines a U-shaped cross-sectional shape when viewed transversely to the longitudinal axis. The teeth and jaws are configured to accommodate multiple dental positions along the dental arch. The dental locations to be brushed, such as the teeth and / or gums, should be at least 1 The recess wall is inserted into one recess and lined with bristles. The upper bristles are actuated to brush the teeth and / or gums. Depending on the length of the recess, some or all of the upper and / or lower arches Dental locations can be brushed simultaneously. An example of such a mouthpiece is This can be found in PCT application Ser. No. 2013 / 013366 filed on April 27, 2018 by has not yet been published as of the priority date of this application.
[0018] Some of such mouthpieces have recessed walls that are lined with bristles. The recess wall is arched in the longitudinal direction, and is laterally spaced from the longitudinal direction. In the cross-sectional direction, the cross section is U-shaped, and the recess wall is , bristles. The small inner space of the U-shaped cross section and the arch shape The length of the recess makes the manufacture of such recess walls lined with bristles very difficult. Naturally, such recesses lined with bristles The wall is recessed by attaching bristles or tufts of bristles one by one to the recessed wall. It can be made manually, however, this is labor intensive and time and cost effective. Such a brush with a U-shaped cross section and bristles on the inner side of the U-shape is not suitable for use. Such recess walls are further produced by co-injection molding the recess walls and the bristles. However, due to the small inner width of the U-shape, the molded recess walls and bristles may be The removal of the bristles from the mould is almost impossible to handle without damaging the bristles. Furthermore, the inner wall of the narrow arch-shaped channel with a U-shaped cross section is tough. Tufting cannot be automated.
[0019] Therefore, a distance at least equal to the distance from the second premolar on the left to the second premolar on the right Simultaneous brushing of multiple dental positions along the arch The present invention relates to a method for producing a continuous recess wall that is lined with bristles for forming a recess. There is a need for a cavity wall that extends from at least the left second premolar to at least and wherein both of the teeth are configured to encompass a dental position associated with a right second bicuspid tooth, U-shaped cross section and at least equal to the distance from the second premolar on the left to the second premolar on the right and an arcuate longitudinal axis spanning a distance.

The first side is the concave inner side of the final U-shape. A further characteristic of the final state is In the final state, the sheet is lined with bristles (bristle sheet The first side of the part is now more concave than it was in its initial state.
[0027] The method includes providing a bristle having bristles to be provided in the providing step. Allowing the seat assembly with the seatbelt to be prefabricated elsewhere, or The first side of the article (i.e., the side that will be lined with bristles) For example, it may be flat, convex, or slightly concave. In this embodiment, it is possible to make the bristled sheet part locally, which is This allows easy access to create seat parts with grooves. In the initial state, the bristles may extend in essentially the same direction from the sheet component. and the bristles may, for example, extend substantially parallel to one another. The bristles may be grouped into one or more groups of parallel bristles, with different The bristles of each group extend in different directions relative to each other. The flat or convex first side of the sheet part in the embodiment is When the bristles are injection molded, the molded sheet parts and the bristles are released from the mold. When the mold halves are removed (see, for example, U.S. Pat. No. 5,333,363), the mold halves can be easily removed. In Patent Document 2, it is stated that a sheet part having bristles for a conventional toothbrush is By injection molding the seat parts in just a few steps, and the tufts of bristles The mold is then inserted into the mold half. The flat or convex first side of the support member also includes a seat member having bristles. To support this, AFT toothbrush technology such as GB Boucherie NV, Bel Options offered by gium or Zah like anchorless toothbrushes Other techniques, such as those from Oransky AG, Germany, may be used.

Similarly, the mandible has a similar number of dental positions, which are classified according to the nomenclature. are named similarly.
[0063] Reference numeral 15 indicates the lingual side of the dental position arc. The inner side of the arc of the dental position is the inner side facing the tongue. The facial side 16 is the outer side of the dental arc, which is the outer side of the cheeks and lips. Like, in your face.
[0064] FIG. 1 further illustrates a system of three mutually orthogonal axes, including an x-axis, X, a y-axis, Y, and a z-axis, Z. The z-axis Z is a curved axis that follows the contour of the dental arch 1. The x-axis Y and the y-axis Y are perpendicular to each other and define the xy plane. is essentially flat and perpendicular to the dental arch 1, i.e., z-axis Each xy plane that intersects a given location on the The z-axis Z defines the curved length direction. The axis Y defines a curved zy plane, which, when viewed along the z axis, corresponds to the shape of the dentition arc. Furthermore, the z-axis Z and the x-axis X define the zx plane.
[0065] FIG. 2a is a perspective view of an example of a mouthpiece 20 made by the method according to the present invention of Chapter 1. FIG. 2b shows a schematic diagram of the structure of the casing as shown by the arrow IIb in FIG. 2a. 2b also shows a cross section of the mouthpiece of FIG. 2a.
[0066] The mouthpiece 20 comprises a body portion 21 provided with a first recess 22. This first recess 22 has a curved length direction when viewed along the z-axis of FIG. 1 and is When viewed from the inside, it has a U-shaped cross section. The first recess 22 is bounded by a recess wall 23. The recess wall 23 is U-shaped in the xy plane. The recess is lined with a plurality of bristles 24, each of which is attached to the recess wall 23. The recess wall 23 is connected to the end of the recess (called the root portion 19) and extends from the recess wall 23 to the first end of the recess (called the root portion 19). 1 and extends into the recess 22 of the first recess 22 .
[0067] Reference numeral 26 denotes a nipple, which is used for pumping and connecting the mouthpiece. The mouthpiece 20 is configured to connect to a right half, a left half, a right half, and / or a suction device. 27 and left half 28, which are, as it were, connected at nipple 26 Be together.
[0068] Reference numeral 25 denotes a curved dividing line, which is defined in FIG. The mirror plane is defined as parallel to the xz plane as shown in Figure 2. The mouthpieces used are, so to speak, mirror-symmetrical to this mirror plane. 2a, it has a second recess (not visible in FIG. 2a but shown in FIG. 2b) on the opposite side of the first recess 22. This means that there is a second recess (which can be seen in Fig. 2b). The upper and lower circles of the dental position are also lined with bristles. The first recess has a different shape than the second recess because the teeth of the arc have different shapes. It is noted that it is possible for the shape to be different.
[0069] The recess 22 is located on the left side of the dental position of the third molar or the second molar on the right side, respectively. Constructed to encompass the entire dental arch up to the 3rd molar or 2nd molar dental position The recess 22 may also be configured to encompass a portion of the arch of a dental position. The part is, for example, from the dental position of the central incisor to the dental position of the second premolar, or , at least five to the first molar dental position or the second molar dental position Includes dental positions.
[0070] FIG. 2b shows a cross section according to the arrow IIb in FIG. 2a of the right part of the mouthpiece 20. There are.
[0071] As can be best seen in FIG. 2b, the bristles are relatively thin. Each tuft 29 may be provided as a tuft 29 of a fiber 24. Each tuft 29 may have a base 36. The base 36 may carry the bristles 24 at their roots 19. and is attached to the recess wall.
[0072] As can be seen in FIG. 2b, the mouthpiece 20 has a body portion 21. The main body 21 has a first recess 22 on its upper side and a second recess 23 on its lower side. Both recesses 22 are bounded by a flexible recess wall 23. In a cross section parallel to the xy plane as defined in Figure 1, The recess wall 23 is U-shaped and includes a recess wall bottom 34 and two recess wall legs 33. The recess wall 23 has two recess wall legs 33 extending from the recess bottom wall. The base 33 and / or bottom 34 of the wall are covered by tufts of bristles 29. It is being done.
[0073] Inside the body, a pressure chamber 35 is provided, which is connected to the nip The fluid can be filled via the valve 26 (FIG. 2a). The fluid can be a gas, such as air, or Alternatively, it may be a liquid such as water. In an embodiment such as that shown in FIG. In this case, the mouthpiece has one pressure chamber. However, the mouthpiece has five The pressure chamber may include multiple pressure chambers, such as one pressure chamber, or any It is noted that other numbers of pressure chambers may be included. Reference 1 shows examples of other numbers of pressure chambers in Figures 4, 5, 7, 9, and 10. In the case of multiple pressure chambers, all or a combination of pressure chambers The group is, according to the present invention in Chapter 1, that described in the unpublished patent application 1. Similarly, the casings may be in fluid communication with one another.
[0074] As can be seen in FIG. 2b, the mouthpiece is It is possible for the lingual preform to include an internal support structure of rigid material. The mask may include a face plate 30 and a face plate 32, both of which are shown in FIG. The y-axis extends along a curved y-plane defined by the y-axis, resulting in a U-shaped The lingual plate 30 and the facial plate 32 are kept at a predetermined distance from each other. To achieve this, the support structure may include one or more spacers 31. The spacer or spacers 31 may be, for example, a plurality of bars or wires or can be a single plate, which is a zx plane as defined in Figure 1. A single plate as a spacer can extend essentially parallel to the surface. In the case of the casing, this plate divides the pressure chamber 35 into two pressure chambers (the upper one These two pressure chambers can be divided into two chambers: the upper chamber and the lower chamber. The plates may be in fluid communication with one another via one or more through holes through the plate. In the case of large through-holes and / or a large number of through-holes, two pressure channels are The member can effectively be one single pressure chamber.
[0075] Mouthpieces such as those shown in Figure 2 allow for simultaneous brushing of multiple dental positions. If teeth are present, the teeth at each dental position are The remaining part in the dental location, such as the gums, is brushed. The area adjacent to the missing tooth may be brushed in the area where the missing tooth may be present. The teeth are additionally brushed with bristles intended for the place of the missing tooth. It can be queried.
[0076] A single pressure chamber 35 bounds the first recess 22 (the upper one in FIG. 2b). The first flexible recess wall 23 defines a second recess 22 (the lower one in FIG. 2b). and a second flexible recess wall 23. The first and second recess walls, among other things, The flexible recess can be deformed by increasing or decreasing the pressure in the recess 35. The wall 23 may be made of a resilient material, such as a rubber-like material. The flexible recess wall 23 may be made of a non-elastic material. There is substantially no or low pressure differential across the outer side. Sometimes the flexible recess wall 23 material is capable of maintaining a predetermined shape.
[0077] The mouthpiece 20 is adapted so that the tufts 29 of the bristles 24 engage the tooth surfaces of the teeth of the dental arch. or one or more dental positions that may be missing teeth. In the case of the above arrangement, the bristles are compressed when the pressure in the pressure chamber 35 is increased. 24 tufts 29 are configured to engage the gums at each dental location. In cases where a tooth may be missing at a given dental position, it is particularly important to The tufts of bristles 29 at the free ends of the legs 33 are aligned with the gums in the empty dental position. The actuator will engage with the actuator.
[0078] When viewed in the longitudinal direction Z of the dental arch (as defined in FIG. 1), The tufts 29 of the fibers 24 are arranged at approximately the same density when viewed in the cross section shown in FIG. It can be placed.
[0079] The pressure in the pressure chamber 35 may be, for example, by pumping fluid into the pressure chamber 35. Thus, or by increasing the amount of fluid in the pressure chamber 35, When the pressure is increased, the recess wall 23 is, so to speak, compacted, closing the recess 22. The bristles 24 (particularly their free ends) are narrowed so that they are tightly pressed against the tooth surface. The pressure chamber can be engaged with and / or deformed against the tooth surface. When the pressure in the reservoir 35 is subsequently reduced, the recess walls are, so to speak, widened and the recess 22 This narrowing and widening of the recess wall may be small, but When the vibration is repeated back and forth at a frequency between 1 Hz and 50 Hz, the wall of the recess The recess wall is reciprocally deformed by reciprocally narrowing and widening the recess wall. is a bridge between a more rigid engagement with the tooth flank and a relatively loose engagement. and / or moving the bristles between a first deformation state and a second deformation state. Alternating, it induces sweeping and / or rubbing of the bristles along the tooth surface. The recess walls obtained by the method according to the invention in Chapter 1 can also be used for other types of masonry. It can also be used in mouthpieces, for example mouthpieces without a pressure chamber. It is noted that the recess wall obtained by the method according to the invention in chapter 1 can be, for example, A mouthpiece is mechanically vibrated as a whole to produce a brushing motion of the bristles. It can be used in pieces.
[0080] By appropriate cycling of increasing and decreasing the pressure in the pressure chamber 35, the mouse Effective brushing action of the pieces can be obtained. Bristles 24 typically undergo upward and downward motion during such cycles. During such a cycle, the bristles 24 at the recess wall legs 33 generally , performing a lateral movement back and forth in the direction of the x-axis as defined in FIG. When the pressure is increased and decreased reciprocally, the recess 22 alternately narrows and widens. Due to this, the bristles 24 at the recess wall legs are also defined as in FIG. The device may be subjected to pivoting back and forth about the z-axis as shown in FIG. Sweeping and / or rubbing of the bristles in the direction of the y-axis as defined resulting in movement.
[0081] Referring to FIG. 1, the width of the tooth element in the X direction varies from approximately 2 mm depending on the dental position. It varies between 10 and 12 mm. It is desirable to keep the mouthpiece as small as possible. Taking this into consideration, the internal width of the U-shape of the recess wall in the X-direction should be as small as possible. should be kept flat and approximately 0 to 2 mm wider than each tooth. As an example to give some indication of the dimensions, The internal width of the U-shape can range from 0mm to 20mm, as viewed in the X direction of Figure 1. and can be in the range of, for example, 2 mm to 12 mm. In the example, the bristles are , 3 mm to 4 mm long. It extends from the opposing recess wall legs 33. There should be no gaps between the bristles or only a limited gap of about 2mm to 4mm. This means that there are still gaps in the amount of Further, as an example to give some indication of the dimensions: The U-shape of the recess wall is in the range of 3 mm to 20 mm when viewed in the Y direction of FIG. For example, the inner height may range from 5 mm to 10 mm. The internal width and internal height measurements are given for an adult. For a child or For animals, these measurements may differ. This limited amount of space is This makes it difficult to manufacture a mouthpiece such as that shown in FIG. For example, the bristles extending from the opposing recess wall legs are essentially in the X direction (the X direction is the The injection molds extend in a direction perpendicular to the direction in which they can be separated from each other. Due to this, injection molding is difficult.

In FIG. 3 (FIG. 3 is schematic), the bristles 104 are , shown in the left half of the bristled sheet component 101, but in reality, The right half of the sheet component 101 and the upper part of the sheet component 101 with bristles are also It is noted that it will be covered by bristles 104 as well.
[0084] FIG. 3a shows the bristled sheet component 101 obtained in the providing step. In this providing step, the bristled sheet component 101 is in an initial state. As shown in FIG. 3a, in the initial state, all the bristles 104 are The bristles 104 extend in the same upward direction. In this initial state, the bristled sheet portion The product 101 is referred to as the "initial shape" when viewed in the xy plane as defined in FIG. 1, and has a cross-sectional shape that is seen along the z-axis as defined in FIG. In FIG. 3a, the bristle sheet component 1 01 is shown as part of sheet 100, but outside of dashed arcs 105 and 106. The remaining part of the sheet on the side may not be present and may have been cut out, for example It should be noted that it is possible that the bristles are arc-shaped. Only the bristled sheet component 101 is present, and the bristled sheet component 101 is not included. Therefore, the rectangular sheet 100 does not exist.
[0085] A cross-section of the bristled sheet component 101 in the initial state as shown in FIG. The "initial shape" of the bristled sheet member 101 is flat. The initial shape of the first side 102 is concave (with the second side 103 becoming convex) or may be convex (with second side 103 being concave).
[0086] FIG. 3b shows the structure of the molded article by thermoforming from the initial state shown in FIG. 3a to the final state. 1 shows a mold 110 for transforming the bristled sheet component 101. The mold 110 has a cavity 111 on its upper side 118. 11 is U-shaped in the xy plane as defined in Figure 1 (see reference 112), and the cavity 111 is a cavity as defined in FIG. In the z-direction, the dental position arc and shape extend along a similar arc. A suction opening 113 can open into this cavity 111 (one Although only one suction opening is shown in FIG. 3b, there are multiple openings distributed throughout the cavity 111. (It is possible that there are several of them.) The cavity has an arc-shaped inner wall at its upper side. It has side edges 115 and an outer edge 116 that is arcuate in shape.
[0087] FIG. 3c shows the half to the left of axis 107, lying on top of mold 110. The sheet 100 is shown with the bristled sheet component 101 overlapping the cavity 111. The inner arc 105 and the outer arc 106 are aligned along the inner edge of the cavity. 115 and outer edge 116. However, the inner arc 105 and the outer arc 106 are formed by the inner edge 115 and the outer edge 116 as viewed in the x direction in FIG. and the inner arc 105 and the outer edge 116 may have a distance greater than that of the inner arc 105 and the outer edge 116. As a result, the side arcs 106 overlie the upper surface 118 of the mold 110. To give rise to.
[0088] Starting from the state as shown in FIG. 3c, the suction force is applied to the suction opening 113 or This suction force can be applied to the cavity 111 through the other. From its initial state shown in FIG. 3 to its final state shown in FIG. 3d and FIG. 3e, The bristled sheet component 101 is thermoformed to form the bristled sheet component 1 01 to provide a recess wall 120 (see also FIG. 4 ), which This can be used as the recess wall 23 in the embodiment of FIG. The cross-sectional shape of the seat part 101 with the hole is a U-shape, and the longitudinal axis is ( The first side is the concave inner side of the final U-shape. In the initial state, the first side may already be concave. In the final state, the first side of the bristled sheet component 101 may be The shape will be more concave than when it was in the state.
[0089] When the bristled sheet component 101 is plastically deformed, 101 can be stretched in a direction along the contour of the U-shape. It is also desirable to have a uniform distribution of bristles when viewed along the contour of the U-shape. In the case where the step of providing is carried out at a higher density, and optionally With uneven distribution (uneven distribution is transformed into even distribution during the transformation step) In the providing step, by providing bristles, This stretching can be taken into consideration when providing the bristled sheet component. .
[0090] Referring to FIG. 3e and FIG. 2b, the final U-shape is formed by two leg pieces 33 and The base part 34 connects these leg parts and is defined by a vertical axis 119. is defined as extending between the leg members 33.
[0091] For clarity of illustration, FIG. 3d only shows the bristles 104 in three locations. However, it is not possible to cover the entire recess wall with bristles. This is evident, for example, when viewed along the z-axis as defined in FIG. The arc is a series of continuous U-shaped bristles as shown in detail in Figure 3e. As can be seen in Figures 3d and 3e, one leg Bristles 104 on the part 33 and bristles 104 on the other leg part 33 extend from each leg part 33 towards each other.
[0092] As can be seen in FIG. 3a, the bristled sheet component is a continuous sheet. It is a bridge part that is connected from the initial state (Figure 3a) to the final state (Figures 3d and 3e). The seat part 101 does not have a cutout to facilitate transformation. .
[0093] FIG. 4 shows a recess wall produced according to the method of the present invention in Chapter 1, e.g. 3d shows a recess wall 120 obtained by the method according to FIG. Although the slots 104 are only shown at the ends and middle of the recess walls, they are not shown in FIG. The inside of the recess bounded by the recess walls as viewed along the Z axis as defined The sides may be completely covered by the bristles 104 .
[0094] FIG. 5 shows the "further providing step" of the method according to the present invention in Chapter 1. In the "further providing step" of the above, the lingual frame member 121 and the facial frame A lingual frame member 121 and a facial frame member 122 are provided. are arcuate in shape and both have upper edges 125 and 126, respectively. Referring to FIG. 2b, the lingual frame member 121 may correspond to the lingual plate 30. Optionally, the face frame member 122 may correspond to the face plate 32. .
[0095] As shown by the bold arrow A between FIGS. 4 and 5, the recess wall 120 is In the step of For this purpose, the inner edge 105 of the recess wall 120 (= the inner arc of the dashed line in FIG. 3) , fixed to the upper edge 125 of the lingual frame member 121 and the outer edge 106 of the recess wall 120. (= the outer arc of the dashed line in FIG. 3) is fixed to the upper edge 126 of the face-side frame member 122. This results in the picture of FIG. 6. The lower edge 123 of the lingual frame member 121 and the lower edge 124 of the face frame member 122 by a closure 127. After closing the mouthpiece according to the present invention in Chapter 1, the face-side frame member 122, the recess The pressure bounded by the wall 120, the lingual frame member 121, and the closure In the direction of the y-axis as shown in Figs. 1 and 4, the lingual flap is When the vertical length of the frame member 121 and the face side frame member 122 is extended, The closure may be a further recess wall, the further recess wall being The mouth is now facing downwards. As shown in FIG. 2b, the lingual frame member and the The outer surface of the face frame member may be molded, for example, by an injection molding process using a bristled shell. The support part may be coated with the same material as the support part.
[0096] As shown by the arrow V in FIG. 6, the lingual frame member 121 and the facial frame member 122 are The curvature of the frame members 122 may be, for example, For example, this can be reduced by compressing the free ends of the arcuate shaped frame members. This results in an increase in the depth of the U-shaped cross section as viewed in the direction of the Y axis in Figures 1 and 4. In other words, the bottom of the U-shaped cross section is formed by the closure 127. This is in addition to the thermoforming transformation of the method of FIG. As an alternative to transformation by molding, the bristled sheet component 101 may be transformed to its final state. If it is used as an alternative to thermoforming, it may be used with bristles. When the seat component 101 is in the state shown in FIG. 6 (similar to FIG. 3a), ) can still be flattened or slightly curved. The transformation step is the process of changing the shape of a material from its flat or slightly curved initial shape to its final U-shape. At the same time, the initial curvature of the bristled sheet part 101 is changed to the original shape. The method includes reducing the curvature of the axial length of the slab to a final curvature of 0.2 mm.
[0097] Referring to FIG. 6, the curvature of the lingual frame member 121 and the facial frame member 122 is This can also be realized by using elastic frame members 121, 122. from a stress-free or unstressed state, in which the frame members The frame members 121, 122 are arranged in a pre-loaded state from a released state. in a folded state (in which the frame members have a wider bow than in the released state) The wider bow corresponds to the initial curvature of the bristled sheet component. In this pretensioned state, the frame portion The members 121, 122 are arranged to hold the frame members 121, 122 in their released state (which is the final state). The pretension acts in a direction that returns the tension to the original tension state (capable of responding to the tension state).
[0098] FIG. 7b shows a view similar to FIG. 6. FIG. 7a shows the arrow VIIa in FIG. FIG. 7a shows a side view of the device as it is obtained in the providing step. The bristled sheet assembly 101 is shown in an initial state. In the embodiment, the bristled sheet component 101 is flat, but the bristles 104 The first side that is lined with the material may be shallowly concave or convex. Figure 7b shows the bristled sheet element 101 in its final state. As shown by arrow C in FIG. 7b, the inner edge 105 and the outer edge 106 are 1 and 4 as defined in FIG. As shown in FIG. 1, the inner edge 1 of the bristled sheet component 101 is 05 (= the inner arc of the dashed line in FIG. 3) and the outer edge 106 (= the outer arc of the dashed line in FIG. 3). Reducing the distance from a wider d2 (see FIG. 7a) to a smaller d1 (see FIG. 7b) By this, the bristled sheet component 101 changes from the initial state shown in FIG. to the final state shown in FIG. 7b. To do so, the This results in an increase in the depth of the U-shaped cross section as viewed in the direction of the Y axis. This can be used in addition to, or as an alternative to, thermoforming transformation. can be used to transform the bristled sheet component 101 into its final state. If it is used as an alternative to thermoforming, the bristle sheet part 101 When the state shown in FIG. 7a is as shown in FIG. 7a, The bristles can be naturally flat or slightly curved. The seat assembly 101 is attached to the upper edges of the frame members 121 and 122. In this case, the transformation step is (similarly as defined in FIG. 1 and FIG. 4) 1. The facial frame member 122 and the lingual frame member 12 in the direction of the x-axis (as shown in This can be implemented by reducing the distance between
[0099] The mechanism described above in connection with Figures 6 and 7 (in short, the arrow V mechanism) The Arrow A mechanism (shown in Figure 6) and the Arrow B mechanism (shown in Figure 7) are both It is essentially a mechanical transformation. Also, the arrow V mechanism and the arrow C mechanism are shown in Figure 8. As shown, they may be used in combination, one after the other, or simultaneously. 8a shows the longitudinal axis L1 of the arch shape and the inner edge of the bristled sheet component 101. 8b shows the initial state with a distance d1 between the outer edge 105 and the outer edge 106, and FIG. , the arch-shaped longitudinal axis L2, the inner edge 105 of the bristled sheet component 101, and the outer edge 1 shows a final state having a distance d2 between the side edge 106, where d2 is d 1 and L2 has a stronger / narrower curvature than L1.
[0100] FIG. 9 shows an example where two sheet parts 101 are provided as a single part 150. Figure 9a shows the single part in a flat state. The single part is held together by the bristles. The sheet member 101 includes two bristled sheets having a first side that is lined with The bristles on this first side are shown as gray, arcuate shaped surfaces. The bristled sheet components are connected by a transition area 151. The row area 151 is a region in which the two bristled sheet components 101 are moved from a first position to a second position. and in the first position, The two bristled sheet elements 101 are aligned (this first position is shown in FIG. 9a). In the second position, the two bristled sheet components are folded over one another. (This second position is shown in FIG. 9b). The part 150 may be placed in the state shown in FIG. 9a or in the state shown in FIG. 9b. 9a and 9b, or in any intermediate state between the states of FIG. 9a and FIG. 9b. If the single part 150 is provided in the state of FIG. 9a or in said intermediate state, the bridge In the folding step, the sheet part 101 with a groove is in the first position (FIG. 9a or FIG. 9a and 9b) to a second position (FIG. 9b).
[0101] FIG. 10 shows a bristled sheet component 101 in an initial state (FIG. 10a), and A further example of the bristled sheet element 101 in its final state (FIG. 10b) is shown in cross section. In the initial state, the first side 102 of the bristled sheet component 101 is The bristled sheet component 101 is supported by the bottom component 34. The base part 33 has two legs 33 interconnected by a vertical axis 160. 34. In the initial state, the bristles 104 are The leg part 3 extends parallel to the vertical axis 160. The angle α of the third element can be, for example, 55° in the initial state. In the step, the leg part 33 is at an angle of x degrees with respect to the vertical axis 160. When the legs are rotated toward each other, the result is that the leg parts 33 are aligned along a vertical axis. The resulting angle will be α-x°, that on leg 33 relative to the vertical axis. The angle of each bristle will be x degrees (see Figure 10b). If x is 45 degrees, Assuming that α can be 55°, the angle of the leg part 33 relative to the vertical axis 160 is The final angle α-x° will be 10°.
[0102] With reference to FIG. 10, the bottom part 34 does not show bristles, but the bristles 104 are shown at the bottom. It is noted that it is also possible for the casing 34 to be present on the other parts 34 as well. For simplicity and illustration of FIG. 10, the leg parts 33 are shown as straight. Although these leg pieces 33 are shown in Figs. 10a and 10b as It may be curved as well, or start straight in FIG. 10a and go to FIG. 10b. It is noted that the curved state may occur at .
[0103] FIG. 11 shows the essentially mechanical transformation of the bristled sheet component 101. In the step of attaching the bristled sheet member, the curvature of the longitudinal axis of the bristled sheet member is narrowed, and and the interrelation between the boundary edge 105 and the boundary edge 106 of the bristled sheet component 101. By reducing the distance d, i.e., the distance d between the inner edge 105 and the outer edge 106, Both effects are illustrated diagrammatically. Figure 11a shows a bristled sheet in its initial state. 11b shows a perspective view of the non-bristled side of the bristle part 101, and FIG. 11b shows the final state.

As can be seen from Figs. 11a and 11b, the bristled sheet component The initial wide curvature of the length axis of 101 (see FIG. 11a) is the The curve is less than the final narrow curvature of the length axis (see FIG. 11b). in the initial state (left) and in the final state (right), with the bristles at location m FIG. 11d shows the cross-sectional shape of the sheet component 101 in the initial state (left side) and and the cross-sectional shape of the bristle sheet part 101 at location n in the final state (right side). Figure 11e shows the initial (left) and final (right) states. (Right side) shows the cross-sectional shape of the bristled sheet component 101 at location o. As can be seen from FIG. 11d and FIG. 11e, the boundary edge 105 and the boundary edge 1 The mutual distance between 06 and d1 in the initial state is smaller than the (smaller) d 2. This transformation can be performed without stretching the sheet part 101. When carrying out the transformation, the narrowing of the curvature of the length axis and the reduction of the mutual distance are simultaneously As shown in FIG. 11c, at position o The cross-sectional shape of the As shown in Figures 11d and 11e, The cross-sectional shape at positions m and n changes from a relatively shallow U-shape to a relatively deep U-shape. Position m and position n are the arch-shaped bristled sheets. The position o is located on a relatively straight part of the t part, and the position o is located on an arch-shaped bristled sheet The final state (Fig. 11b, Fig. 11c, Fig. 11d and the right part of FIG. 11e), and from position m to position When viewed in the direction of o, the change in cross-sectional shape from a blunt U-shape to a sharp U-shape (V-shape) is This corresponds to the change in the cross-sectional shape of the dental arch. has an approximately V-shaped cross-sectional shape when viewed in a plane perpendicular to the length of the human dental arch. and the molars and premolars have a generally U-shaped cross-sectional shape. Canines, on the other hand, have a cross-sectional shape that is somewhere between a V-shape and a U-shape.

[0106] The embodiment of FIG. 13 can be realized in two variants by the method according to the invention of chapter 1. 2 shows a schematic diagram of an example of a bristle sheet component assembly 201 fabricated into a wall. The seat part assembly 201 has an inner arc / (wall) in the direction of the longitudinal axis of the arch shape. Bristle bounded by edge 105 and outer arc / (wall) edge 106 The seat part assembly 201 includes a seat part 101 having an inner boundary edge 105. and further including an inner attachment member 231 extending along the entire inner boundary edge 105 thereon; Also, on the outer boundary edge 106, there is an outer attachment that extends along the entire outer boundary edge 106. Additionally, the seat component assembly 201 includes a lingual frame 232. The face frame member 30 and the face frame member 32 further include an inner attachment member 231 and an outer The attachment members 232 are attached to the inner boundary edge 105 and the outer boundary edge 106 as shown in FIG. The lingual flap may be shaped as a side flap protruding from each of the boundary edges 106. The frame member 30 and the face side frame member 32 are formed by a plate as shown in FIG. It can be shaped as:
[0107] The seat part assembly 201 of FIG. 13 is provided with a flat seat as shown in FIG. In the flat initial state, or in the U-shaped initial state of FIG. 13b, or The tips 231, 232 and the plates 30, 32 are attached to the bristle sheet component 101. In an initial state, the prefabricated A prefabricated part may be provided as a prefabricated part, for example by injection molding (e.g. For example, the seat part A in FIG. The assembly can be manufactured, for example, by injection molding (e.g., multi-material injection molding techniques). It may be produced during the providing step.
[0108] The seat component assembly 201 is a prefabricated assembly that is fabricated prior to the providing step. In both cases, whether as a part or produced during the providing step , it may be made by injection molding (eg, multi-material injection molding technique, etc.). 29 tufts with 24 bristles (optional, already pre-assembled) It is placed as an insert in the injection mold and the base of the tuft (which is optional) Alternatively, a base 36 may be provided for each tuft as shown in FIG. The mold cavity protrudes into the area where the mold 1 is to be formed. After closing the mold, the first and second plastic materials are injected into the mold. One material forms the lingual frame member 30 and the facial frame member 32, and the second material forms the , forming the seat component 101, the inner mounting member 231 and the outer mounting member 232. The interface between the frame members 30, 32 and the mounting members 231, 232 At 250, the frame members 30, 32 and the mounting members 231, 232 are The sheets are then adhered to each other due to the fused interface layer that is formed. The second material forming the part 101 is overmolded with the base 36 of the tuft and The base 36 and the sheet component 101 are firmly bonded to each other. The bond may result, for example, from the encasing of the base within the sheet part. and / or fusion at the interface of the second material and the base 36. Alternatively, the lingual frame member and the facial frame The parts are prefabricated and, like Tuft, are inserted into the injection mold as inserts. In this case, the seat parts and the mounting member Only the second material is injected to form the mounting member and This results in a fused interface layer. The mounting member is then attached to the mounting member.

In a step of forming the molded article (which may be, for example, by thermoforming and / or mechanical deformation), (e.g., by narrowing the curvature of the longitudinal axis of the sheet part) , and / or reducing the distance between the inner boundary edge 105 and the outer boundary edge 106. As a result, the seat part assembly 201 is assembled as shown in FIG. In the embodiment of FIG. 13, the transforming step includes thermoforming. However, as mentioned above, this is done by two types of mechanical deformation. This can be done by either thermal or by a combination of these two methods. Shape and mechanical deformations may be combined in the transforming step.
[0110] As can be seen in FIG. 13c, the tufts 29 / bristles 24 are In addition, in Figs. 13a and 13b, Even so, the 29 tufts / 24 bristles are distributed in a regular pattern. Due to the stretching of the wall piece 101 between the steps, The distance is increased in FIG. 13c with respect to FIG. 13a and FIG. 13b. In this example In the past, this stretching was regular across the U-shape, but it is irregular. Taking into account the stretching, the tufts / bristles may be 13b in the initial state, and in the final state of FIG. 13c, the tufts / bristles ( It is intended to have a predetermined distribution (such as a regular distribution).

[0142] According to the present invention in Chapter 2, the dental cleaning device includes a pressure sensor and a controller. The pressure sensor is configured to measure a pressure representative of the pressure in the pressure chamber. The pressure sensor may be disposed, for example, in the pressure chamber, the pressure sensor being Alternatively, the pressure sensor may be connected to the pump unit and the pressure chamber. in the inlet tube (e.g., near the pressure chamber) that is located between and the pressure sensor measures the pressure of the fluid entering the pressure chamber. The pressure in the pressure chamber may be calculated and / or estimated. The sensor is located in the inlet tube between the pump unit and the pressure chamber. For example, the pressure sensor may be located near the pump, and the pressure sensor may measure the pressure of the fluid exiting the pump unit. From said pressure, the pressure in the pressure chamber is calculated and / or estimated. Further alternatively, the pressure sensor may be integrated with the pump unit. , the pressure of the fluid leaving the pump unit is measured. From said pressure, the pressure in the pressure chamber is calculated. The pressure may be calculated and / or estimated.
[0143] While measuring the pressure in the pressure chamber, the pressure is measured using a reference pressure (e.g., ambient pressure The relative pressure can then be measured, and the measured pressure can be compared to a reference pressure ( Alternatively, absolute pressure measurements can be made and measured in a pressure chamber. The absolute value of the pressure is measured.
[0144] According to the present invention in Chapter 2, the pressure sensor and the controller are connected. The pressure sensor and the controller are disposed in communication with each other, and a signal is transmitted from the pressure sensor to the controller. A connection can be sent from the server to the controller (and / or vice versa). For example, the pressure sensor may be a wired or wireless connection. It produces a pressure signal representative of the pressure (in the pressure chamber) measured by the force sensor. The pressure signal is sent to the controller when the dental cleaning device is in use. A controller receives the signal.
[0145] According to the present invention in Chapter 2, the controller generates a control signal based on the pressure signal. For example, the control signal may be generated to indicate that the pressure in the pressure chamber is too high or It is possible to indicate whether the control signal is within a certain bound or is too low. The signal may be generated continuously, for example, when the pressure in the pressure chamber is too high. When the pressure signal indicates this (when the pressure exceeds a preset upper threshold), the control signal The signal corresponds to a control signal that is generated when the pressure in the pressure chamber is within a predetermined boundary. Therefore, the change in the control signal can be It is possible to show that the chair is not functioning as desired. The pressure signal indicates that the pressure in the force chamber is below a preset upper threshold. When indicating, the control signal can have other characteristics. For example, the pressure The control signal generated when the upper threshold is below the set threshold is It is possible to indicate to the pump unit that the device is functioning as desired. do.
[0146] The control signal may alternatively be a switch type signal. The signal of the pressure sensor is generated only when the pressure exceeds a certain threshold or it is switched on. The control signal is generated only when the pressure is within the desired boundaries. , may not be generated continuously.
[0147] According to the present invention in Chapter 2, the controller and the pump unit are connected. That is, the controller and the pump unit are disposed in communication with each other, and a signal is It can be sent from the controller to the pump unit (and / or vice versa). The connection may be, for example, a wired or wireless connection. When the controller generates a control signal, the signal is In use, the signal is delivered to a pump unit which receives the signal. In response to a control signal, the pump unit pumps fluid into and / or into the pressure chamber. The device provides a predetermined delivery dose out of the barrel.
[0148] So, in doing its job, the pump unit can pump, say, from 0 liters per minute to 4 Fluid is pumped into and out of the pressure chamber at a rate of between liters per minute. The pump unit pumps a preset amount of air into and out of the pressure chamber. The control signal may then be configured to deliver a determined amount of fluid (liters per minute). When receiving the , the pump unit continues its operation with the current delivery amount. It is possible to increase, decrease or increase the amount of delivery. If too much pressure is measured in the pressure chamber, the delivery rate may be increased. Generating a control signal based on the pressure being maintained below a predetermined upper threshold. Alternatively, the control signal can be set to This means that the delivery rate of the pump unit should be altered. This shows that:
[0149] According to the present invention of the second chapter, the controller of the dental cleaning device is When the side threshold is exceeded, the controller reduces the amount of delivery. The pump unit pumps the pressure into the pressure chamber when the pressure in the pressure chamber exceeds an upper threshold. The pump may be configured to reduce the amount of air pumped into the cylinder. As a result of reducing the pressure in the pressure chamber, the dental cleaning device While allowing the device to operate more efficiently (e.g., it consumes less power, which means less battery life). (which may result in batteries needing to be recharged less frequently) Therefore, while improving its performance, it also prevents excessive pressure from damaging the user's teeth or gums. Prevents brushing.
[0150] Furthermore, by controlling the pump delivery rate via a control signal based on the pressure measurement , brushing the teeth with excessive pressure is prevented.
[0151] The dental cleaning device according to the present invention of Chapter 2 has at least one recess. The mouthpiece includes a mouthpiece having at least one recess, for example, one or two recesses. The at least one recess may have a U-shaped cross section. The piece includes, for each said recess, a recess wall defining a boundary of the respective recess. The recess wall may be formed from a sheet. The sheet is made of, for example, a thermoplastic elastomer, a silicone elastomer, or a silicone. The recess walls may be made of a polymer. The recess walls may be optionally lined with a plurality of bristles. The bristles are arranged in a recessed portion, and one end of the bristles is attached to the recessed portion wall. Each of the mouthpieces has a recess wall and extends into the recess. a recess having a recess wall supported by bristles distributed across the recess wall; At least one dental position (the tooth element of this position, The dental position is such that the gums covering the jawbone at that location are received within the recess. The bristles in the recesses, if present, may be recessed to face the lingual side (i.e., to the user's tongue). on both the face side (facing the user's lips / cheeks) and the face side (facing the user's lips / cheeks), as well as the preferred Preferably, at least the free end surface of the tooth (the chewing surface / edge facing the opposing jawbone) is also In this way, one dental position can be brushed at a time. When you press the brush, the active bristles (if any) point towards the user's teeth. The spool may be made from nylon, elastomer, or any other suitable material. In the case of an edentulous arch, the remaining arch of gums also requires treatment. In this case, the gums are held by the recess walls with or without bristles. For improved gum cleaning, the cleaning fluid may be massaged into the gums. It may be used in such mouthpieces that do not include a rissle.
[0152] The mouthpiece of the present invention of Chapter 2 is configured to contain a fluid under pressure. At least one pressure chamber is provided, the pressure of which can be increased and decreased. The body is adapted to reciprocally (alternately) increase and decrease the pressure in at least one pressure chamber. and reducing the pressure on the recess wall to deform the recess wall and (if present) causes a continuous, repeated reciprocating motion of the bristles on the recess wall. The mouthpiece is a single piece that can be filled with a fluid, as described in U.S. Pat. No. 5,399,363. , two, three, four, five, six, or any other number of pressure chambers. It is possible that the document is in the name of the same applicant and is also Alternately (reciprocally) in at least one of the pressure chambers The pressure in the pressure chamber is increased from a reduced pressure state to an increased pressure state. from an increased pressure state to a decreased pressure state, and By continuously repeating the motion, the recess walls carrying the optional bristles are moved. The recess walls and the bristles are each disposed at a dental position so that the recess walls and the bristles are disposed at a dental position so that the dental position and cleaning the object by acting on the teeth and / or gums present at the position. To result in.
[0153] The recess is bounded by a recess wall. The flexible deformable recess wall can define the boundary of the pressure chamber, i.e. However, alternatively, the recess wall may be one or more rigid pressure It is also possible that it is formed by a force plate.
[0154] Regarding the terminology of "increased pressure state" and "decreased pressure state", The states are related to each other, i.e. in a reduced pressure state, the pressure is It is noted that the sigma-based approach is reduced (lower) for In both conditions the pressure can be lower than ambient pressure.
[0155] The length of the mouthpiece (transverse to the U-shaped cross section) is aligned with the user's dental arch. The width of the teeth (measured by the teeth width) can be roughly equal to the width of a human or animal tooth. The user of the dental cleaning device is then brushed. along the arch (e.g., first along the mandibular arch and then along the maxillary arch, It is possible to move it (or vice versa). The length of the tooth can be at least five teeth long and the length of the tooth can be at least five teeth long. For example, the length of the mouthpiece can be adjusted to suit the mouthpiece position. The length (measured transversely to the cross section of the U-shape, along the user's dental arch) is , the following lengths may be measured: - From the second premolar on the left side to the second premolar on the right side of the human (e.g. adult) dental arch a length spanning a distance at least equal to the distance of; - From the first molar on the left side to the first molar on the right side of the human (e.g. adult) dental arch a length spanning a distance at least equal to the distance of - substantially the entire length of the user's dental arch so that the entire arch can be brushed simultaneously distance (i.e. at least the arch from the second molar on the left to the second molar on the right) The length it reaches.
[0156] Additionally, the length axis of the arch shape may be similar to the shape of a human dental arch, or It may have a shape similar to at least a portion of the shape of a human dental arch.
[0157] The dental cleaning device according to the present invention of Chapter 2 is provided with a pressure chamber in fluid communication with the pressure chamber. The pump unit further includes a pump unit disposed in the pressure chamber. by pumping a predetermined volume of fluid into and out of the pressure chamber, respectively. The pressure in the pressure chamber is increased and decreased between these two states. The recess wall is configured to be deformed by increasing and decreasing the pressure applied to the recess wall. The pump unit is then moved back and forth to increase and decrease the recess, respectively. The pumping action increases the pressure in the pressure chamber. For example, the pump unit continuously increases and decreases the pressure in the pressure chamber. a pumping device configured to pump a fluid into the pressure chamber; a suction device configured to draw fluid out of the increased pressure and alternately increasing the pressure in the pressure chamber between said reduced pressure state and said reduced pressure state. The recess walls are moved back and forth alternately to increase and decrease the pressure in the recesses. By increasing and decreasing the amount of brushing, the user's teeth and / or gums are This improves the user's oral hygiene.
[0158] In a further embodiment of the first aspect of the invention in Chapter 2, the pump is operated at a predetermined operating frequency. (e.g., within a narrow frequency range around this given operating frequency) Alternatively, the controller may be configured to operate at a predetermined operating frequency (e.g., (e.g., within a narrow frequency range around the operating frequency of Further, alternatively or additionally, "when the pressure in the pressure chamber exceeds a predetermined upper threshold value, Configuring the controller to "reduce delivery of the pump unit when Changes in the operating frequency are prevented.
[0159] Settings such as bristle length, bristle stiffness, flexible deformable recess wall characteristics, etc. Brushing / cleaning of dental cleaning devices according to meter parameters The effect may be optimal at a particular operating frequency. The cleaning device is also used when using the dental cleaning device. After the control signal indicates that the upper pressure threshold has been reached, the operating frequency (The pressure in the pressure chamber is increased and decreased reciprocally.) For example, if the fluid in the pressure chamber is a gas, the pressure Reciprocatingly increasing and decreasing the pressure in the chamber at higher frequencies This can be ineffective in exercising the recess walls and can be uncomfortable for the user. This also applies when the fluid is a liquid. Furthermore, flexible, deformable recess walls are used. When the pressure chamber is in a high frequency range, the recess walls reciprocate to increase the pressure in the pressure chamber at a higher frequency. and may not deform in response to a decrease in
[0160] Therefore, the operation of the dental cleaning device may be changed after the indication. When changing the operating frequency (the pump unit operates at that operating frequency or According to this further embodiment, the pump is operated at a predetermined operating frequency. The operating frequency is not changed.
[0161] The predetermined operating frequency may be a fixed value, for example 8 Hz. According to the present invention in Chapter 2, it is possible to reduce the pump delivery without affecting the pump operating frequency. It is possible that the intention is to control the amount of power that reaches the target, but as a side effect of the control, Ripples can occur, for example, at a fixed given operating frequency of 8Hz: Ripple in the range of ±0.5Hz to ±1Hz is possible.
[0162] Additionally, the predetermined operating frequency can vary as a function of time. If so, the pump unit will operate as a predefined function of the time measured after switching the pump on. It is therefore possible to have a varying operating frequency. In formula, this is expressed as ft=x( Each time the pump is switched on, a given function is x(t) is a given continuous or discontinuous function of time. For example, the operating frequency may start at a low frequency at t=0 and then increase to a higher frequency. Rising to a higher frequency and then finally (after, say, 20 to 30 seconds) slowing down to a lower frequency It is possible to start at a lower frequency. It is possible to prevent the user from having a startle reaction and to end at a low frequency. It gives the user an indication that brushing is almost complete. On the other hand, a frequency in between is necessary for good brushing results. Also, according to the present invention in Chapter 2, it is possible that It may be intended to control the pump delivery rate without affecting the operating frequency. As a side effect of the control action, ripples in the operating frequency can occur, e.g. Note that ripples in the range of ±0.5Hz to ±1Hz may occur. It is intended.
[0163] The predetermined operating frequency may be a fixed operating frequency or a time-varying operating frequency. In both cases the operating frequency can range from 0.5Hz to 20Hz. .
[0164] In another further embodiment of the first aspect of the invention in Chapter 2, the upper threshold is 2 bar relative to ambient pressure, e.g. 1 bar relative to ambient pressure Too much pressure in the pressure chamber can be harmful to the user of the dental cleaning device. This can result in an unpleasant user experience and can lead to excessive brushing force. In addition, too high pressure can easily result in the rupture of the recess wall. may cause harm to users and / or damage to the This results in economic loss of the indirect cleaning device. The above mentioned upper threshold of at most 2 bar is likely low enough to exclude these adverse effects. Preferably, the upper threshold is at most 0.3 bar above ambient pressure ( 1.3 times) and, for example, a maximum of 0.2 bar relative to ambient pressure (1. At such pressures, the brush of the dental cleaning device The cleaning effect is still sufficient, but on the other hand, there is a risk of damaging the gums of the user, and and reduces the other adverse effects mentioned.
[0165] Direct pressure measurement (where absolute pressure is measured) is described in the present invention in Chapter 2. However, this may be difficult to achieve in a talc cleaning device. It is noted that instead of measuring absolute pressure, a comparison with a reference pressure (e.g., ambient pressure) is made. It is envisaged that this will be done to determine the pressure in the pressure chamber. For example, the expression "0.3 bar above ambient pressure" refers to the particular measurement being made. Alternatively, "approximately 1.3 times the ambient pressure" or "approximately 1.3 bar pressure" may be used. Ambient pressure can refer to, for example, geographic location, height, and It depends on weather conditions and is generally known to be around 1 bar anywhere on Earth. .
[0166] In yet another further embodiment of the first aspect of the invention in Chapter 2, the controller , for example, in an increased and / or decreased pressure state, the pressure chamber When the pressure in drops below a predetermined lower threshold, the delivery volume of the pump unit Similar to the situation where the pressure in the pressure chamber is too high, Additionally, too little pressure can also adversely affect the operation of the dental cleaning device. For example, when the pressure is too low, the bristles of the dental cleaning device However, it may not be possible to rub the device against the user's teeth with sufficient force, resulting in insufficient tooth contact. This results in cleaning / brushing. According to an embodiment, the delivered volume (and therefore the pressure in the pressure chamber) is controlled by the pressure chamber pressure. When the pressure therein drops below the lower threshold, it is increased.
[0167] In a further refinement of this embodiment, the lower threshold value is greater than the upper threshold value by 1 bar. That is, the maximum pressure difference in the pressure chamber (control The pressure (allowed by the roller) can be less than 1 bar. For example, When the threshold is 1.3 bar (ambient pressure plus 0.3 bar), the lower threshold is 0. 3 bar (ambient pressure minus 0.7 bar). For example, the upper threshold The difference between the value of the lower threshold and the value of the lower threshold can be 0.4 bar. The nominal pressure difference between the reduced pressure state and the increased pressure state is the upper threshold value and the lower threshold value. It is possible that the difference between , the upper and lower thresholds may not be reached every pressurization cycle. For example, when the difference between the upper and lower threshold values is 0.4 bar, the The nominal pressure difference between the increased and decreased pressure states is only 0.1 bar or 0 It is possible for the pressure to be .2bar.
[0168] In another refinement of this yet another embodiment, the lower threshold is -0. Can be in the range of 5bar to +0.2bar (0.5 to 1.2 times ambient pressure) For example, from -0.5 bar to 0 bar (0.5 times the ambient pressure) The pressure in the pressure chamber can be in the range of In the reduced pressure state, the pressure can be below ambient pressure, while in the The pressure in the chamber can be above ambient pressure in the reduced pressure state. It is.
[0169] According to the second aspect of the present invention in Chapter 2, a method for brushing simultaneously at multiple dental locations is provided. A dental cleaning device for cleaning a dental tissue is provided, teeth, - a mouthpiece having a pressure chamber and a recess, the recess being defined by a recess wall; The recess may be bounded by a wall, the wall of the recess may be flexible and deformable, and the recess may include: The recess has a curved longitudinal direction and a U-shaped cross section transverse to the longitudinal direction. The curved lengthwise direction extends from at least the second premolar on the left to at least the second premolar on the right. The pressure chamber is configured to include that portion of the user's dental arch that extends to the molars. the nozzle is configured to contain a fluid under pressure; and a mouthpiece; - optionally a plurality of bristles, one end of which is attached to the recess wall; a plurality of bridges each having a recess and extending into the recess away from the recess wall; Sulu and; - a pump unit arranged in fluid communication with the pressure chamber, Pumping a predetermined volume of fluid into and out of the pressure chamber, respectively. By this, the pressure in the pressure chamber is changed between an increased pressure state and a decreased pressure state. The pressure is reciprocally increased and decreased to deform the recess wall. , the recess wall is moved back and forth to increase and decrease the recess respectively, and the pump unit a pump unit that, when in operation, operates at a predetermined operating frequency; Including, The operating frequency is in the range of 0.5Hz to 20Hz.
[0170] The mouthpiece of the dental cleaning device according to the second aspect of the invention in Chapter 2 comprises: Similar to the mouthpiece of the dental cleaning device according to the first aspect of the present invention in Chapter 2 Additionally, the mouthpiece recess has a curved length direction. A substantial portion of the user's dental arch (e.g., substantially the entire dental arch, etc.) in a longitudinal direction. For example, the recess is configured to include at least the first left molar. 10. The method of claim 1, further comprising: or at least in the area from the second molar on the left to at least the second molar on the right The dental position may then be configured to include all of the teeth in the user's dental arch. Or almost all teeth are brushed simultaneously with a dental cleaning device. It can be searched.
[0171] The dental cleaning device according to the second aspect of the present invention may optionally further comprise: The bristles of the dental cleaning device according to the first aspect of the present invention in Chapter 2 are similar to those of the dental cleaning device according to the first aspect of the present invention. It has a number of bristles.
[0172] The dental cleaning device according to the second aspect of the present invention in Chapter 2 is A pump unit similar to the pump unit of the dental cleaning device according to the first aspect of the present invention Includes .
[0173] According to the second aspect of the present invention in Chapter 2, the pump unit has a frequency of 0.5 Hz to 20 H It operates at an operating frequency in the range of z.
[0174] In contrast to known dental cleaning devices, which operate at significantly higher frequencies, In contrast, the dental cleaning device according to the second aspect of the present invention in Chapter 2 is For example, the device disclosed in the patent document 2 operates at a relatively low frequency (compared to devices from the prior art). The dental cleaning device operates at a frequency between 100Hz and 300Hz. This high frequency movement is caused by the bristles (which, in US Pat. No. 5,333,363, are made of nylon and This allows the septum (attached to the membrane) to act as a jackhammer, The jackhammer functionality removes tooth pullers from the user's teeth using the dental cleaning device. However, such high frequencies are required to remove bristles. In fact, the inertia of the total fluid volume, Difficulty in overcoming cavitation effects in the fluid created by pumping action Patent document 2 teaches how to solve these problems. Regarding dental cleaning devices that operate like a hammer, It is generally accepted that high frequencies (regardless of the difficulty) are required. The reason is that otherwise it would take too much time to clean the teeth, and dental cleaning This is because users of the device are unable to adequately clean their teeth.
[0175] The dental cleaning device according to the second aspect of the present invention in Chapter 2 is compared with Patent Document 2. It takes a fundamentally different approach compared to the conventional bristles, which move the bristles at very high frequencies. Instead of finding a suitable method to make the dental cleaning device according to the present invention, The vise uses a fairly low operating frequency of 0.5Hz to 20Hz to brush teeth. The pressure in the pressure chamber is increased reciprocally by the lower operating frequency compared to the higher operating frequency. Adding and decreasing the amount of heat generated is much more energy efficient. The dental cleaning device according to the second aspect provides a mouthpiece including a recess, The portion is configured to encompass substantially the entire dental arch of a user and has a U-shaped cross section. So (almost) every tooth and every side of each tooth has The dental cleaning device according to the second aspect of the present invention of Chapter 2 simultaneously brushes and When operating the bristles at lower frequencies, the jack handle can be Instead of acting as a brush, the bristles act as windscreen wipers, so to speak. The device can be used to rub against the user's teeth as it is moved toward the teeth, The rubbing action removes plaque from teeth. The rubbing action is 0.5Hz~20H This can only be effectively implemented at relatively low frequencies in the range of z. When the number is too high, there is a jackhammer rather than a rubbing action. There is a "bending" effect, which requires frequencies much higher than 20 Hz. When the wave number is lower than 0.5 Hz, the movement is too slow and rubbing can be performed satisfactorily. , the total brushing time is increased too much.
[0176] The dental cleaning device according to the second aspect of the present invention in Chapter 2 provides a method for cleaning the dental arch. Scrub teeth to remove plaque from teeth at substantially all dental locations simultaneously so that arch cleaning can still be performed in a satisfactory amount of time. , a very efficient alternating movement of the recess walls and the bristles results.
[0177] It operates at a relatively low operating frequency and stimulates substantially all of the user's dental arch by rubbing the teeth. The proposed dental cleaning device brushes all teeth simultaneously. , incorrect use and ineffective brushing of the teeth makes it almost impossible.
[0178] Additionally, brushing the teeth with a relatively low operating frequency reduces the Resulting in a more comfortable mouth feel when using the talc cleaning device It is possible.
[0179] In a further embodiment of the second aspect of the invention in Chapter 2, the operating frequency is between 1 Hz and These frequencies are in the range of 3 to 15 Hz, for example, 3 to 10 Hz. The operating frequency range is determined on the one hand by the desired brushing time and on the other hand by the brushing result achieved. It provides an optimal trade-off between performance and cost.
[0180] In another further embodiment of the second aspect of the invention in Chapter 2, the operating frequency is The predetermined frequency may be fixed or time-varying. As explained in relation to the first aspect of the invention in Chapter 2, due to the amplifier being configured to operate at a given operating frequency, or This is due to the controller being configured to operate the pump at a given operating frequency. , this predetermined frequency may be maintained when responding to pressure changes, for example.
[0181] In a further embodiment of the first and / or second aspect of the invention in chapter 2, the recess The walls shall be rated at 20 Shore A, measured in accordance with ISO 7619-1:2010. The recess walls are made of a material having a hardness of 100 Shore A. The material is made of an elastomer, such as a thermoplastic elastomer or a silicone elastomer. Hardness from 20 Shore A to 100 Shore A, e.g. 50 Shore A Materials with hardnesses between 80 Shore A and 80 Shore A are suitable for continuous repeated deformation. When shaped, it offers the best trade-off between flexibility, deformability, stiffness, and durability. It is possible to do so.
[0182] In a further embodiment of this, at least some of the bristles are made from materials with hardness ranging from 20 Shore A to 100 Shore A. For example, the bristles may be made of a thermoplastic elastomer or a silicone elastomer. The range may be made from elastomers such as silicone polymers. Providing bristles with an optimal trade-off between stiffness, flexibility, and deformability On the one hand, it is possible to increase the durability of the bristles and actually clean the teeth. It is desirable for the bristles to be relatively hard so that they rub against the teeth with sufficient force to clean the teeth. On the other hand, the dental cleaning device is used to scrub the teeth of the user to clean said teeth. (instead of damaging the teeth) and harder bristles It is desirable for the bristles to be easily deformed to reach those hard to reach spots.
[0183] In another embodiment of the first and / or second aspect of the invention in chapter 2, the recess wall is , 10 to 50 Shore D measured according to ISO7619-1:2010 The recess walls are made of a material with a hardness of 0 Shore A. Plastics, such as polyethylene, polybutylene terephthalate, polypropylene , polyester, or nylon. 0 Shore D hardness, for example, 70 Shore D to 90 Shore D A material with a hardness of 0.01 mm (used in the thin recess walls) is highly resistant to continuous repeated deformation. It provides an optimal trade-off between flexibility, deformability, stiffness, and durability. It is possible.
[0184] In a further embodiment of this, at least some of the bristles are made from materials with a hardness of 50 Shore D to 100 Shore D. For example, the bristles may be made of plastic, such as polyethylene, polybutylene, etc. It may be made from terephthalate, polypropylene, polyester, or nylon, etc. This range is between finer bristles with appropriate stiffness, flexibility and deformability. On the one hand, it is possible to provide the bristles with an optimal trade-off between to increase durability, while still providing enough force to actually clean your teeth. For scrubbing purposes, it is desirable for the bristles to be relatively hard. To scrub the teeth of a user of the device to clean said teeth (rather than damaging the teeth) instead, and to reach spots that are difficult to reach with harder bristles In addition, it is desirable for the bristles to be easily deformed.
[0185] In another elaboration of this further embodiment, the bristles and the recess walls are made of the same material. Alternatively, the bristles are made of a material with a hardness significantly higher than 70 Shore D. while the recess walls may be made of a nylon material having, for example, 40 Shor Thermoplastic elastomers with hardness ranging from 100 Shore A to 100 Shore A or silicone elastomer.
[0186] In another further embodiment of the first and / or second aspect of the invention in Chapter 2, The mouthpiece of the dental cleaning device has two of the recesses, The recesses each have a U-shaped cross section and are bounded by the recess walls. The openings of the U-shaped cross sections of the two recesses face in opposite directions. Allows simultaneous brushing of the teeth and / or gums of the lower and upper arches To perform.
[0187] In another further embodiment of the first and / or second aspect of the invention in Chapter 2, The recess or the two recesses have an elongated curved shape, and at least one of the recesses is Five dental positions, for example, ranging from the first molar on the left to the first molar on the right This is advantageously configured to include multiple dental positions. This allows for simultaneous brushing of the teeth at each position. The grooves are removed in less time compared to dental cleaning devices with shorter recesses. The recess can be realized by a denture extending from the second molar on the left to the second molar on the right. The mouthpiece may be configured to accommodate the third molar (wisdom tooth) position. The dental arch may extend over substantially the entire dental arch of the user, with or without inclusion of any of the following:
[0188] In another further embodiment of the first and / or second aspect of the invention in Chapter 2, When using the dental cleaning device, increasing the pressure in the pressure chamber The bristles of the dental cleaning device are deformed at the end portions of the bristles ( The tooth is moved toward the user's dental position while being rubbed against the tooth. This rubbing action of the recording portion cleans the teeth. In contrast to the conventional dental cleaning device, the dental cleaning device according to the present invention in Chapter 2 The throttling device does not function as a jackhammer; instead, it The bristles and teeth act as a cleaning mechanism to remove dental plaque from the teeth. Use the friction between your teeth to rub them together.
[0189] In certain embodiments of the first and / or second aspects of the invention in Chapter 2, the fluid comprises: It can be a gas, preferably air. Air is readily available, e.g. For example, it may be extracted from the environment while operating a dental cleaning device. The use of fluids may require the use of closed-loop fluid systems, which This can be more expensive and laborious to produce. In some cases, an open loop or partially open loop system may be used, where the fluid is For example, to allow the exit of the pressure chamber to the outside of the dental cleaning device. It is tolerated.
[0190] In an embodiment of the second aspect of the invention in Chapter 2, the dental cleaning device comprises: configured to measure a pressure representative of the pressure in the pressure chamber; a pressure sensor configured to generate a pressure signal representative of the pressure; and a controller configured to control the pressure sensor and the controller.

The pressure is at a constant level.
[0200] The mouthpiece 320 includes a first recess 322. The first recess 322 is shown in FIG. When viewed along the z axis, it has a curved length, and when viewed in the xy plane of FIG. The first recess 322 has a U-shaped cross section. Bounded by recess wall 323, flexible and / or deformable recess wall 323 is U-shaped in the xy plane.

The mouthpieces being used are, so to speak, mirror-symmetrical with respect to this mirror plane. It has a second recess (not visible in FIG. 22) on the opposite side of the first recess 322. This means that there is a This second recess is also lined with bristles. First, because the upper and lower arches (of teeth) generally have different shapes, It is noted that the recess can have a shape different from the shape of the second recess. can be.
[0204] The recess 322 may be, for example, a tooth that is spaced apart from the dental location of the right third molar or second molar. Involves virtually the entire dental arch up to the dental position of the left third molar or second molar, respectively As regards the first aspect of the present invention in Chapter 2, the recess 322 is also configured to , may be configured to encompass a portion of the arch of a dental position, which portion may be, for example, a single Contains only one dental position.
[0205] 23a and 23b show the right part of the mouthpiece 320 as indicated by the arrow XXI in FIG. 22. The cross section shown is taken along line II of FIG. 23b. The pressure in the pressure chamber is shown in FIG. 23a. 23a) and the pressure in the pressure chamber is increased to (relative to the situation in FIG. 23b) is reduced.
[0206] As can be best seen in Figures 23a and 23b, the bristles are Each tuft 329 may be provided as a tuft 329 of substantially fine bristles 324. The bases 336 may have a base 336 at their roots 319. The recess 322 carries bristles 324 at its center and is attached to a flexible recess wall 323.
[0207] As can be seen in Figures 23a and 23b, the mouthpiece 320 The upper side of the plate has a first recess 322 and the lower side has a second recess 3 22, with the upper recess 322 and the lower recess 322 being opposite each other. Both recesses 322 are bounded by flexible recess walls 323. In a cross section parallel to the xy plane as defined in FIG. 21, the recess wall 3 23 is U-shaped and has a recess wall bottom 334 and two recess wall legs 333. The recess wall 323 is formed on the recess bottom wall 322 and has two recess wall legs 333 extending from the recess bottom wall. The tufts of bristles 329 on the legs 333 and / or bottom 334 of the wall It has been barred.
[0208] A pressure chamber 335 is provided inside the mouthpiece. The can be filled with fluid via nipple 326 (FIG. 22). The gas can be a gas such as argon or a liquid such as water. In one embodiment, the mouthpiece has one pressure chamber. A piece may include multiple pressure chambers, such as five pressure chambers. It is noted that the pressure chamber may include any other number of pressure chambers. The unpublished patent application 3 shows other numbers of pressure chambers in Figs. 4, 5, 7, 9, and 10. In the case of multiple pressure chambers, all pressure chambers or The group of pressure chambers is, according to the invention in chapter 2, described in the unpublished patent application 3. The fluidic components may be in fluid communication with one another, as well as being connected to one another.
[0209] As can be seen in Figures 23a and 23b, the mouthpiece is made of a flexible It is possible to include an internal support structure of a rigid material relative to the recess wall 323 material. The support structure may include a lingual plate 330 and a facial plate 332. 21, both of which extend along the curved zy plane defined in FIG. As a result, it has a U-shape when viewed along the z-axis. To maintain the ports 332 at a predetermined distance from each other, the support structure may include one or more spacers. The one or more spacers 331 may include: For example, it can be a number of bars or wires or a single plate; It may extend essentially parallel to the zx plane as defined in FIG. In the case of a single plate as a spacer, this plate is Dividing the chamber 335 into two pressure chambers (an upper chamber and a lower chamber) These two pressure chambers can be connected by one or more pressure chambers passing through the plate. The through holes can be in fluid communication with each other. In the case of multiple through holes, the two pressure chambers effectively become one single pressure chamber. It is possible that the
[0210] Mouthpieces such as those shown in Figure 22 allow for simultaneous brushing of multiple dental positions. If teeth are present, the teeth at each dental location are The remaining part in the dental location, such as the gums, is brushed. The area adjacent to the missing tooth may be brushed in case of possible tooth loss. The missing tooth is additionally brushed by a bristles intended for the place of the missing tooth. It can be sung.
[0211] The single pressure chamber 335 is located in the first recess 322 (upper part in Figs. 23a and 23b). a first flexible recess wall 323 that defines a second recess 322 (FIG. 23a and FIG. 23b). and a second flexible recess wall 323 that defines the upper and lower portions of the recess (FIG. 23b). The first and second recess walls 323, among other things, increase or reduce the pressure in the pressure chamber 335. The flexible recess wall 323 can be made of a material such as rubber. The flexible recess wall 323 may be made of any elastic material. The pressure differential across the inner and outer sides of the flexible recess wall 323 When there is virtually no pressure difference or a low pressure difference (in the pressure chamber) When the pressure in the recess is substantially equal to the ambient pressure, the material of the flexible recess wall 323 is formed into a predetermined shape. It is possible to maintain the state.
[0212] The mouthpiece 400 has tufts 329 or bristles 324 that engage with the surfaces of the teeth in the dental arch. or one or more teeth that may be missing In the case of the dental position, at least when the pressure in the pressure chamber 335 is increased, The tufts 329 or bristles 324 engage the gums at each dental location. In cases where a tooth may be missing at a given dental position, In this case, in particular, the tufts 329 of bristles at the free ends of the recess wall legs 333 are vacant. It will engage the gums in the dental position.
[0213] When viewed in the longitudinal direction Z of the dental arch (as defined in FIG. 21), The tufts 329 of the sul 324 are shown in the cross-sections shown in Figures 23a and 23b. Sometimes they may be arranged at approximately the same density.
[0214] 23a and 23b, the pressure in the pressure chamber 335 may be, for example, By pumping fluid into or within the pressure chamber 335 When increased pressure is reached by increasing the amount of fluid, the recess walls 323 is, so to speak, compacted, narrowing the recess 322, thereby 24 (particularly its free end) is capable of firmly engaging the tooth surface; and / or it may be deformed by contacting the tooth surface; situation in Figure 23b (teeth not shown). When the pressure in the chamber 335 is subsequently reduced, the recess walls are, so to speak, widened, Enlarge the recess 322; the situation in FIG. 23a (again, teeth not shown). This narrowing and widening of the recess wall can be small, for example 0.5 When the vibrations are repeated at a frequency between 50 Hz and 20 Hz, the walls of the recess are narrowed in an alternating manner. Alternately deforming the recess walls by narrowing and widening the recess walls provides a more intimate contact with the tooth flank. Moving the bristles between firm engagement and relatively loose engagement; and / or alternating the bristles between a first deformation state and a second deformation state, which includes: This causes the sweeping and / or rubbing of the bristles along the tooth surfaces.
[0215] By appropriate cycling of increasing and decreasing pressure in the pressure chamber 335, the mouse The bottom 334 of the recess wall is attached to the blade 320, and an effective brushing action of the blade 320 can be obtained. Bristles 324 typically undergo upward and downward motion during such cycles. The bristles 324 at the recess wall legs 333 generally have such a size. During the rotation, the user's teeth are moved back and forth in the direction of the x-axis as defined in FIG. Or perform lateral movements.
[0216] As an example only to give some indication of the dimensions, and referring to FIG. For reference, for an adult, the width of the tooth element in the X direction is approximately It varies between 2mm and 12mm. It is desirable to keep the mouthpiece as small as possible. Taking into account that the recess wall is to be inserted into the cavity, the internal width of the U-shape of the recess wall in the X-direction should be as small as possible. should be kept small enough that it is approximately 0 to 4 mm wider than the width of each tooth. As an example to give some indication of the dimensions, The internal width of the U-shaped part wall is in the range of 0 mm to 20 mm when viewed in the X direction of Figure 21. The thickness can be in the range of, for example, 2 mm to 12 mm. The spool can be up to 6 mm long. The stem is 3 to 4 mm long, which is formed from the opposing recess wall legs 333. There should be no gaps between the bristles extending from the brush, or the gap should be about 2mm to 4mm. This means that there is a limited amount of space remaining. The gaps are shown exaggerated. As an example, the U-shape of the recess wall is in the range of 3 mm to 20 mm when viewed in the Y direction in FIG. For example, the inner height may range from 5 mm to 10 mm. These internal width and internal height measurements are given for adults. For different individuals or animals, these measurements may vary.
[0217] Increasing and decreasing the pressure in the pressure chamber 335 is accomplished by a pump unit. Different pump unit and valve combinations are possible, where: One possible embodiment is described with reference to FIG. 24. FIG. 24 shows a handle member 502. and a mouthpiece 400 (e.g., as described above) connected thereto. A dental cleaning device 500 including a mouthpiece and a partially cut-away The handle member 502 provides a handle interface. and the mouthpiece 400 is provided with a mouthpiece interface; The mouthpiece interface is removably coupled to the handle interface. The handle member 502 is configured to include a battery for storing electrical energy. The battery 510 is connected to the battery through a battery charging interface 512. The battery 510 can be fed to the battery 510 via a printed circuit board (PCB). 514, a motor 516, a transmission 518, and a crank piston 520. , a piston pump 522, and a main pump unit 504 including, optionally, 524. The pump 524 collects the mouthwash liquid. A mouthwash capsule 530 is removably housed within the handle member 502. The piston pump 522 can be a pneumatic pump. Instead of pumps, also diaphragm pumps, plunger pumps, membrane pumps, or A bellows pump may also be used. The mouthwash pump 524 is preferably a hydraulic pump. It is possible.
[0218] The dental cleaning device 400 further includes a pressure sensor 540. 540 is shown here very diagrammatically and is positioned near the duct 542. The pressure sensor 540 is configured to measure a pressure representative of the pressure in the pressure chamber. and configured to generate a pressure signal representative of said pressure. From the pressure of the fluid at the inlet of the duct 542, the pressure sensor 540 detects the pressure in the pressure chamber The pressure sensor 540 can estimate or determine the pressure in the 4 (here integrated with PCB514) and can communicate with the controller 524 is adapted to receive a pressure signal from a pressure sensor 540 .
[0219] As previously mentioned, the dental cleaning device 400 includes a controller 52. 4, where controller 524 is integrated with PCB 514. The controller 524 controls the pressure based on the pressure signal it receives from the pressure sensor 540. The controller 524 is configured to control the pump unit 504 to generate a signal. 5, the pump unit 504 can receive control signals from the controller 524. In response to a control signal received from the controller 524, the pump The unit 504 controls the delivery volume (relief volume) into and / or out of the pressure chamber. The delivery rate of the pressure chamber increases and decreases as the pressure increases. When the pressure in the pressure chamber exceeds a predetermined upper threshold, a control signal is generated. When indicates, the delivery rate of the pump unit 504 is reduced and the pressure in the pressure chamber Allow it to decrease again and drop below the threshold.
[0220] Thus, the operation of dental cleaning device 500 is controlled by PCB 514. The PCB 514 includes a controller 524. The PCB 514 includes a motor 516. The PCB 514 controls the operation of the pump unit 504, which includes a dental cleaning The device 500 is controlled to pump pressure into and out of the pressure chamber by a pump unit 504. By controlling the amount of fluid delivered out of the force chamber, Pressure is alternately increased and decreased in at least one pressure chamber provided.
[0221] This control of pressure in the pressure chamber by providing a predetermined delivery volume is shown in FIG. This is explained more graphically in the context of Figure 25. What can be seen in Figure 25 is the sinusoidal line. The sinusoidal lines represent the pressure in the pressure chamber as it is increased and decreased back and forth. The horizontal lines indicate the variation due to the Shown are an upper threshold TU and a lower threshold TL. The upper threshold TU can be, for example, , it can be at most 2 bar above ambient pressure, e.g. For example, the maximum pressure is 1 bar, 0.3 bar, or 0.2 bar. It is possible to set the lower threshold TU at a maximum of -1 bar relative to the upper threshold TU. For example, up to -0.4 bar for the upper threshold TU. For ambient pressure the lower threshold TL can be from -0.5bar to +0. The range of the pressure can be up to 2 bar (for example, up to 0 bar). According to the description, when the pressure exceeds an upper threshold TU, the pump delivery is reduced. When the drop falls below a lower threshold TL, the pump delivery rate may be increased.
[0222] Starting from the left side of FIG. 25, at timestamp t0, the fluid is It takes roughly two normal pressurization cycles to pump the gas through the tank, increasing the pressure therein. A pump is shown in which the pressure is between an upper threshold TU and a lower threshold TL. The amplifier operates at a frequency f, which is determined by the time between two successive pressure peaks. The normal delivery volume D1 can be derived from the lower pressure peak represents the amount of fluid pumped into the pressure chamber between the upper pressure peak and the lower pressure peak ( During normal operation of the pump. For example, dental contact with (part of) the user's dental arch. Depending on the fit of the leaning device and the bite pressure exerted by the user, The pressure always remains between the upper threshold TU and the lower threshold TL. Indeed, in this scenario is shown for the first two compression cycles. However, the upper threshold TU and the lower The exact pressure for threshold TL varies for each individual user, as indicated by arrow B. It is possible that the
[0223] At timestamp t1, the pressure in the pressure chamber suddenly increases dramatically. This can occur, for example, from a position close to the incisors (which are typically relatively narrow) to a position close to the molars (which are They have proposed a method for positioning dental cleaning devices close to the teeth (typically relatively wide). The wider the teeth between the recesses, the larger the pressure chamber size. Alternatively, such a sudden increase in pressure can For example, increased bite pressure by the user and / or use of dental cleaning devices. This can be caused due to increased force exerted on the teeth by the user.
[0224] After a period of time, the dental cleaning device reduces the pump's delivery rate D2. In this example, the reduction in delivery is due to the increase in pressure (one This is sufficient to bring the pressure just below the upper threshold TU (within the pressure cycle), but This may require more than one, e.g., two, three, or four, pressurization cycles. The response of the pump unit is now somewhat faster than the occurrence of a pressure increase. It is further noted that it is delayed.
[0225] The delivered volume D2 is reduced once to achieve the desired effect of reducing pressure below the upper threshold TU. After that, normal operation continues again with the same delivery amount D1 as before timestamp t1. do.
[0226] In the example of FIG. 25, at timestamp t2, a sharp drop in pressure in the pressure chamber occurs. This is observed, for example, when a dental cleaning device is moved from a position near a molar When moved toward a position near the incisors and / or when actuated by the user When the applied pressure applied by the user is reduced and / or the bite pressure applied by the user is This can occur when the
[0227] The dental cleaning device achieves this by increasing the pump delivery volume D3. In this example, the increase in delivery is in response to a decrease in pressure at the lower threshold T L . Therefore, the pressure in the pressure chamber is not sufficient to bring the The increased delivery rate D3 is maintained until the pump unit The response of now lags somewhat behind the onset of the reduced pressure, and the pressure falls below the lower threshold TL It responds only when the pressure drops significantly below the By the time the drop is noticed (perhaps even before the lower threshold is reached) the response has already been made. It is possible to say that.
[0228] In the embodiment of FIG. 25, the lowest pressure experienced in a pressurization cycle is the lower threshold T The pressure is increased until it exceeds L. In some cases, the pressure is simply increased during the pressurization cycle. The maximum pressure of the pressure sensor 1 is increased to a level between the upper threshold TU and the lower threshold TL. In that case, only one increased delivery dose D3 may be required.
[0229] Preferably, the operating frequency of the pump unit does not change when the delivery rate is changed. It is noted that the operating frequency of the pump unit remains at a predetermined frequency and The frequency of the can be in the range of 0.5Hz to 20Hz and it is fixed The value may be constant or may vary as a function of time.
[0230] FIG. 26 shows how the dental cleaning system works after increasing the pressure in the pressure chamber. The walls 533 and bristles of the brushing device are moved toward the user's teeth. The end portions of the bristles are deformed and rub against the teeth. The rubbing action of the removes dental plaque from the teeth.

[0235] Chapter 3 [Name of invention] A mouthpiece for brushing at multiple dental positions, A brushing device including a mouthpiece such as or how to operate the brushing device
[0236] The present invention in the third chapter relates to the field of dental cleaning devices, in particular, The present invention relates to a mouthpiece for simultaneous brushing in the dental position. The disclosure further relates to a brushing device comprising a mouthpiece according to the invention in Chapter 3. Moreover, the present invention in Chapter 3 provides a method for operating such a mouthpiece or brushing device. The mouthpiece is designed to operate in at least five dental positions simultaneously. It is designed to be brushed.
[0237] [Chapter 3: Background Technology] Cleaning of human and animal teeth is a prerequisite for oral hygiene and internal organ health. For example, there are various dental cleaners, including manual and electric toothbrushes. These typical toothbrushes do not effectively remove plaque. To remove plaque, brush your teeth using the prescribed method for at least two minutes a day. However, the average person does not have enough time to clean their teeth regularly. Do not spend all your time on brushing, but always brush in an effective way. In addition, toothbrushes may be harmful to the disabled, elderly, or children. Brushing your teeth can be difficult because a typical toothbrush This requires precise positioning of the brush bristles on the various surfaces of the teeth. Additionally, people may exert too much pressure on the brush bristles while brushing their teeth. This can lead to rapid and excessive wear on the bristles as well as The lashing process becomes less effective, teeth can become damaged, and gums can recede. This can have detrimental effects on dental health.
[0238] As is frequently the case in older adults, some or all of the teeth may be missing. If used, cleaning of the gums in these dental locations may still be possible. , is a prerequisite for oral hygiene and internal organ health.
[0239] To clean the teeth and / or gums in these dental locations, There exists a need to automatically brush the teeth and / or gums at these dental locations. There is a need for effective brushing, which reduces the time and effort required. In addition, there is a need to avoid having to carefully manipulate the brush.
[0240] A dental cleaner that includes a mouthpiece that covers both the upper and lower arches. Such a mouthpiece is a brush equipped with bristles. The cleaning surfaces move automatically to clean a complete set of teeth. will be done.
[0241] The mouthpiece and brushing surfaces of known dental cleaning devices are The mouthpiece requires adjustment to closely fit the shape of the patient's dental arch. However, the dental arch may be divided into several sections, so it is important to be able to clean all tooth surfaces. There is a large discrepancy between different users due to different sizes, malocclusions, and missing teeth. Therefore, dental cleaning equipment with adjustable mouthpieces is There is a need for a device.
[0242] The reference patent document 1 discloses an electric dental cleaning device equipped with a mouthpiece. This known mouthpiece discloses a method for cleaning the upper jaw / upper dental arch. It has an upper part and a lower part for cleaning the mandible / lower dental arch. Both the upper and lower parts of the known mouthpiece each have a brush pad. This brush pad has a U-shaped cross section and bristles on the inside of the U-shape. These two brush pads are aligned so that the bottoms of the U-shapes of the pads are aligned with each other. facing each other and the U-shaped legs of the upper brush pad meet the U-shaped legs of the lower brush pad. The legs of the letter shape (which point in a downward direction) point in an upward direction opposite to the The brush pad is positioned as shown in Figure 1. The brush pad is located on the outside of the U-shape, on the rigid brush. The russet plate, the leg plate at each leg, and the bottom of each U-shape and a bottom plate transverse to the foot plate. The lash pad is driven up and down against the free ends / tops of the teeth in the direction of the legs of the U-shape In some embodiments, the bladder is disposed between the upper and lower arches of the mouthpiece. i.e. between the bottom plates, and an alternating or oscillating pneumatic Pressure and suction are applied to the bladder, causing the bottom plates to move relative to one another. It is possible to cause the U-shaped brush pad to move up and down, which So, brush your teeth.
[0243] In one embodiment of the mouthpiece according to the referenced patent application WO 2005 / 023364, flexible fingers are and / or the use of a bladder, which allows the side / leg brush plates to brush the lingual and facial surfaces of the teeth. The flexible fingers and / or bladders are positioned against the side of the A force is applied along the lingual and facial sides of the teeth in a given direction, transverse to the direction of static pressure. While moving up and down in the opposite direction, place the tips of the bristles on the brush plate on the lingual and facial sides of the teeth. The mouthpiece is adjustable in that it is configured to engage with the
[0244] In Patent Document 1, the brushing movement is merely a 1D movement (one-dimensional movement). The reason is that the U-shaped brush pads move towards and away from each other. This is because it can only be done.
[0245] The mouthpiece according to US Pat. No. 5,399,633 has the disadvantage of a limited brushing action. The reason is that the bristles on the brush pad are mounted on a rigid plate. This is because they are limited in their ability to reach all surfaces of the teeth.
[0246] References 2003 / 0173114 (which has the corresponding European Patent Application Publication No. discloses several embodiments of a device for cleaning teeth, It is designed to embrace one tooth at a time, so to speak, to clean one tooth at a time. The first type of device is The brushing movement of the bristles against the teeth is triggered by the hand. Ensures a static brushing pressure of the lissle, i.e. the brush head fits snugly against the hand grip The hand grip is attached to the top of the brush and moves along the teeth like a regular toothbrush. In this first type, one single pressure channel is operated to move the A pressure bubble or two opposing pressure bubbles create cleaning between each individual bristle tuft and tooth. is used to ensure that the contact pressure is at least approximately equal throughout In the first type, the brushing movement of the tuft is caused by the hand. However, the second type of brushing movement of the device is automatically performed by the drive. The second type of device (shown in Figs. 10 to 21 of Patent Document 2) is The tuft is configured to be driven to perform a 2D movement (movement in two dimensions) relative to the tooth surface. Each tuft is aligned perpendicular to the dental arch (i.e., In the first stage, the tines are driven to move in a plane perpendicular to the teeth being The tuft is moved toward the tooth to press against the tooth, after which the tuft is removed from the gums and into the tooth. The tooth is moved axially along the tooth surface in a direction toward the top / crown of the tooth, followed by This moves the tufts away from the surface, reducing the pressure and initiating the next cycle. Then, move the tuft from the top / crown of the tooth back towards the gums. In this second type, Thus, pressure bubbles can be used to actuate the tufts to perform this 2D movement. In these embodiments, the tufts are attached to the rigid cleaning element carrier. The pressure valve is connected directly or indirectly via a rocker arm to the Acts on rigid cleaning element carriers.
[0247] The automated mouthpiece according to Patent Document 2 has the disadvantage of limited brushing. The reason is that the tufts are mounted on a rigid carrier. This is because the tufts are limited in their ability to reach all surfaces of the teeth. A further disadvantage of the system is that only one tooth at a time is cleaned in an automated fashion. and that the automated system of Patent Document 2 is used to clean all teeth. The mouthpiece must be moved manually along all the teeth, which is time consuming That is what it means.
[0248] Therefore, an automatic device that is fast and thorough when cleaning multiple teeth simultaneously is used. There remains a need for a comprehensive range of cleaning devices. There remains a need for an automatic dental cleaning device that requires less effort. It also provides automatic dental cleaning that effectively reaches virtually all tooth surfaces. There remains a need for the device.
[0249] Further reference is made to Patent Document 3, filed by the applicant on April 27, 2018. The patent document 3 of the same name has not yet been published on the priority date of this application, i.e. The mouthpiece according to the applicant's previous application is capable of treating the upper and lower dental arches in one go. All teeth in the upper and lower arches can be brushed with the bristles provided The pressure chamber has at least one flexible wall member. The flexible wall member is deformable by alternately increasing and decreasing the pressure of the fluid in the chamber It is structured as follows. [Prior art document] [Patent documents]

[0251] [Summary of the invention in Chapter 3] The object of the present invention in Chapter 3 is to provide an alternative method for brushing at multiple dental positions. The third object of the present invention is to provide a mouthpiece, particularly an automatic brushing device, that is suitable for use with dental implants. A further object of the present invention is to provide an improved method for brushing at multiple dental positions. and providing a bra that is provided with the improved mouthpiece. Another further object is to provide a dental implant device that is suitable for use in multiple dental locations. A mouthpiece for brushing teeth using a toothbrush and a brush containing such a mouthpiece The present invention provides a brushing device, which is similar to the brushing devices known from the prior art. Overcome one or more of the disadvantages of each of the mouthpiece and brushing device More specifically, the present invention in Chapter 3 is subject to the disclosure of unpublished patent document 3 or patent application Ser. Providing a mouthpiece with improved brushing action, such as one in Patent Document 1 The purpose of the Act is to provide
[0252] According to the first aspect of the present invention in Chapter 3, one or more of the above objects are achieved by the use of an undisclosed The present invention provides a mouthpiece according to claim 65, which has a preamble known from the patent document 3 of the same name. This is achieved by providing
[0253] According to the present invention in Chapter 3, the mouthpiece is capable of simultaneously blacking out multiple dental positions. In other words, the brush is provided for brushing at multiple dental locations simultaneously. The mouthpiece is configured to receive natural or artificial teeth. If the ment is present at the dental position where the mouthpiece is brushing, The tooth element is brushed. The tooth element is brushed by the mouthpiece. If the appropriate dental position is not present, the gums may be brushed.
[0254] The mouthpiece according to the invention of Chapter 3 comprises a body portion provided with at least one recess. The at least one recess can be one or two recesses. At least one recess has a curved longitudinal and transverse U-shape. and having a cross section of at least five dental positions as viewed in a curved longitudinal direction. The body portion is configured to define a boundary for each of the recesses. The recess wall may be a sheet, for example. For example, plastics such as polyethylene, polypropylene, polyester, or nylon, or an elastomer, for example a thermoplastic elastomer or silicone. The recess wall may be made of a reflective cone elastomer or the like. The recess wall may be lined with a plurality of bristles. The bristles may be formed by attaching one end of each of the bristles to the recess wall. and extending from the recess wall into the recess. In other words, the body portion has a recess. and the walls of the recess may be covered by bristles distributed over the walls of the recess. At least five dental positions (the tooth elements of these positions or their The gums covering the jawbone at the location of the jaw bone may be received in the recess. Also, if present, the bristles in the recesses provide at least five dental positions. The bristles are made of nylon and elastomer. or any other suitable material. The remaining arch of the gums may also require treatment. In this case: The gums can be massaged by the bristles-free recessed walls. Improved gum cleaning For cleaning, cleaning fluid is introduced into such a mouthpiece that does not include bristles. It can be used in.
[0255] According to the invention of the third chapter, the body is configured to contain a fluid under pressure. At least one pressure chamber is provided, the pressure of which can be increased and decreased. The body portion reciprocally increases and decreases pressure in at least one pressure chamber. The recess wall is deformed by applying pressure to the recess wall and the recess wall. Causes a sustained, repeated oscillation of the bristles (optionally provided on the wall) Thus, the body portion is a single piece that can be filled with a fluid, as described in US Pat. 1, 2, 3, 4, 5, 6, or any other number of pressure chambers. The document is under the name of the same applicant and was not yet published on the priority date of the present application. Reciprocatingly increasing the pressure in at least one of the pressure chambers from a reduced pressure state. and decreasing the pressure in the pressure chamber from the increased pressure state. By reducing the pressure to a constant level, and by continuously repeating this reciprocating motion, Thus, the recess wall (optionally carrying the bristles) is moved, and the recess wall and the bristles Each of the lenses represents an object at a dental location (the teeth and and / or gums) resulting in cleaning of the object.
[0256] Regarding the terminology of "increased pressure state" and "decreased pressure state", The states are related to each other, i.e. in a reduced pressure state, the pressure is It is noted that in both conditions the pressure is , for example, it may be below atmospheric pressure.
[0257] Atmospheric pressure is the pressure present in the room where the mouthpiece user is when using the mouthpiece. Generally, atmospheric pressure is assumed to be approximately 1 bar absolute. However, the actual value of atmospheric pressure depends, among other things, on the altitude relative to sea level and on meteorological conditions. This will be the case.
[0258] According to the invention of the third chapter, the recess wall is configured to be locally deformable, Or, in other words, it is configured to have such local deformability and ("Pressure chamber" in the force chamber or one or more of said at least one pressure chambers) "in the chamber or one or more of said at least one pressure chamber" means "in the The at least one pressure chamber is provided with a pressure reciprocating mechanism (to be further named "pressure chamber"). When the pressure is increased or decreased locally, the shape of the recess wall changes locally, Under increased pressure, the bristles (or, in the absence of bristles, the recess walls) ) is pressed against the dental position, and the shape of the recess wall is such that the dental The local shape of the recess wall is adjusted to the local shape of the recess location, whereas in the reduced pressure state, the shape of the recess wall is adjusted to the The localized pressure distribution of the dental site encompassed by the recess wall is greater than that of the increased pressure state. Therefore, the recess walls are not locally adjusted to the shape of the It is possible for the material to have a smooth surface (without any unevenness) which, when pressure is increased, The locally deformable recess walls accommodate the irregular contours of the dental site (including the bristles between them). The surface becomes uneven due to the fact that it is, so to speak, pressed against the surface (without any consideration for the surface condition). The recess walls are thus locally adjusted to the shape of the dental position at that location. This adjusted shape under applied pressure can be a fit adjustment. (In the fit adjustment, the shape of the recess wall is, so to speak, identical to the contour of the dental position. ), which does not have to be the case, and in fact may not be the case. When the pressure is reduced, the recess walls will return to their initial orientation. , locally unregulated shape (vs. regulated shape at increased pressure) This locally unadjusted shape is adjusted to some extent to the local shape of the tooth contour. It is possible that the regulation will be less clear. This change in the shape of the recess wall between a locally regulated shape and a locally unregulated shape. The results show that the bristles can reach better into the interdental spaces. and increasing and decreasing pressure in at least one pressure chamber. This results in additional movement of the bristles in addition to the movement already caused by the This additional movement results in an additional sweeping effect of the bristles. The concavity between the locally regulated and locally unregulated shapes Taken together the changes in wall shape result in an improved brushing action.
[0259] According to a further embodiment of the first aspect of the invention in chapter 3, the recess wall is encompassed by When viewed longitudinally along the lingual and facial sides of the dental location, the recess walls are in a reduced pressure state. In this case, it is possible to have less relief than in the increased pressure condition.
[0260] According to a further embodiment of the first aspect of the invention in chapter 3, the local deformability of the recess wall The local change in the shape of the recess wall between the increased and decreased pressure conditions is Pressure differences in the range up to 2 bar, e.g. pressure differences in the range up to 0.4 bar The pressure difference may be configured to occur at the pressure chamber in the increased pressure state. The pressure in the pressure chamber is calculated by subtracting the pressure in the pressure chamber under the reduced pressure condition from the pressure in the pressure chamber. The expression "pressure difference in the range of x bar" means that the pressure difference is zero (zero is meant to indicate a pressure difference such as from x bar (excluding x bar) to x bar (including x bar) It is necessary to keep the pressure difference between the increased and decreased pressure states below 2 bar. This prevents the user from experiencing an intolerable pressure difference. Maintaining the pressure difference between the increased and decreased pressure states is generally acceptable. This results in the recess wall being experienced by the user as being The local deformability is the change in the shape of the recess wall between the increased and decreased pressure states. At pressure differences with local variations in the range of up to 0.2 bar (or even lower) The pressure drop can be configured to occur at low pressure differentials.
[0261] According to a further embodiment of the first aspect of the invention in chapter 3, said at least one pressure The pressure in the chamber is higher than atmospheric pressure in the reduced pressure state. is possible.
[0262] Atmospheric pressure is the pressure present in the room where the mouthpiece user is when using the mouthpiece. Generally, atmospheric pressure is assumed to be approximately 1 bar absolute. However, the actual value of atmospheric pressure depends, among other things, on the altitude relative to sea level and on meteorological conditions. This will be the case.
[0263] According to a further embodiment of the first aspect of the invention in chapter 3, said at least one pressure The pressure in the chamber is at most 2 bar above atmospheric pressure in the increased pressure state. For example, at most 1 bar relative to atmospheric pressure. is possible.
[0264] According to a further embodiment of the first aspect of the invention in chapter 3, said at least one pressure The pressure in the chamber is at most 0.3b below atmospheric pressure in the increased pressure state. ar, e.g., at most 0.2 bar relative to atmospheric pressure. It is possible to achieve a satisfactory brushing action with a maximum pressure of 0.3 bar. Risk of harm or injury in the event of a recess bursting, although some The brushing action is still satisfactory with a maximum pressure of 0.2 bar. It is something that can be achieved with one's feet.
[0265] According to a further embodiment of the first aspect of the invention in chapter 3, said at least one pressure The pressure within the chamber is less than atmospheric pressure in the reduced pressure state.
[0266] According to a further embodiment of the first aspect of the invention in chapter 3, said at least one pressure The pressure in the chamber is between -0.5 bar and atmospheric pressure in the reduced pressure state. It can be in the range of -0.5 to +0.2 bar for atmospheric pressure, for example. It can range from -0.5 bar to 0 bar. The reduced pressure reduces the likelihood that the recess walls will be damaged. The pressure can range from -0.4bar to -0.25bar. The reduced pressure, which is in the range of -0.4bar to -0.25bar, is relatively can be realized by inexpensive means. When the pressure is reduced to a reduced pressure state, a vacuum is created in the pressure chamber. This means that the pressure below atmospheric pressure is used for reduced pressure conditions. Using a toothbrush means that the chances of damaging the gums of the user are significantly reduced. is doing.
[0267] According to a second aspect of the invention in Chapter 3 (which comprises one or more other It may be separate from or combined with the above aspects. The present invention relates to a method for manufacturing a multi-density densified ... This second embodiment provides a mouthpiece for simultaneous brushing at the dentition and dentition positions. To define the shape, a system of three mutually orthogonal axes, including the x-axis, y-axis, and z-axis, is used. The z-axis is defined as a curved axis that follows the contour of the dental arch (e.g., the adult dental arch). The x-axis and the y-axis are perpendicular to each other and define an xy-plane, The mount of this second embodiment is flat and perpendicular to the curved z-axis. The piece includes a body portion provided with at least one recess. As with the other embodiments described above, in use, the mouthpiece is placed in the mouth of the user. Therefore, the dimensions of the mouthpiece are determined based on the insertion into the user's mouth.

The body portion includes a recess wall for each of the recesses, and the recess wall defines a boundary of each recess. The present invention also provides a method for providing a plurality of bristles, as described in Section 3, other aspects of the present invention. As in the case of the bristles, the bristles can be flexible and / or deformable. Each bristles has a fixed end, the fixed end is attached to the body at the recess wall. The fixed ends of the bristles may be attached, for example, to the recess walls. Each bristles may be attached to another part of the body. The bristles extend into the recess toward the free ends of the bristles, the free ends being disposed in the recesses. According to this second aspect, the body portion has the plurality of dental positions enclosed within a recess. When included, a first reciprocating pivotal movement about a first pivot axis, a second pivot axis a second reciprocating pivotal movement about the line and a reciprocating translational movement along the translation axis; The fixed ends of the bristles (e.g., each free end of each bristles) a first pivot axis, a second pivot axis, and a second pivot axis. The translational axes are mutually perpendicular, and the first pivot axis is parallel to the z-axis. The second pivot axis and the translation axis extend in the xy plane. Configuring the body portion to subject the ends to these movements reduces the pressure chamber and recess walls. (which is locally deformable and carries fixed ends of the bristles) A different attachment of the fixed ends of the bristles can be achieved by the main body (see also the next paragraph). and / or different drives for subjecting the fixed ends of the bristles to these movements. This can also be achieved by:

The boundary between the first flexible recess wall 623 and the second recess 622 (the lower one in FIG. 29) and a second flexible recess wall 623 defining a recessed portion 624. The first and second recess walls include, inter alia, , can be deformed by increasing or decreasing the pressure in the pressure chamber 635. The flexible recess wall 623 may be made of a resilient material, such as a rubber-like material. Alternatively, the flexible recess wall 623 may be made of a non-elastic material. There is substantially no or low pressure differential across the inner and outer sides of 623. When a force differential is present, the material of the flexible recess wall 623 maintains a predetermined shape. is possible.
[0304] The mouthpiece 700 is configured such that the tufts 629 of the bristles 624 engage the tooth surfaces of the teeth of the dental arch. or one or more dental implants that may be missing teeth. In the case of the barrel position, at least when the pressure in the pressure chamber 635 is increased, the brake The tufts 629 of the ristle 624 are adapted to engage the gums at each dental location. In the case where a tooth may be missing at a given dental position, In particular, the tufts of bristles 629 at the free ends of the recess wall legs 633 are The gums will be engaged in position.
[0305] When viewed in the longitudinal direction Z of the dental arch (as defined in FIG. 27), The tufts 629 of the sul 624 are shown in the cross-sections of Figures 29a, 29b, and 29c. When viewed from above, they can be arranged at approximately the same density.
[0306] FIG. 29a illustrates a first operating state (also called an intermediate state) of mouthpiece 700. The pressure in the pressure chamber 635 is equal to or greater than atmospheric pressure in the intermediate state. It can be lower than atmospheric pressure or higher than atmospheric pressure. do.
[0307] FIG. 29b illustrates, for example, by pumping fluid into pressure chamber 635 or By increasing the amount of fluid in the pressure chamber 635, the pressure chamber 635 increases. 1 illustrates a second operating condition of mouthpiece 700 when under applied pressure. As can be seen in FIG. 29b, as a result of increasing pressure, the recess wall 62 3 is, so to speak, compacted, narrowing the recess 622 (with respect to FIG. 29a), thereby Therefore, the bristles 624 (particularly their free ends) can be firmly engaged with the tooth surfaces. It may be possible and / or may be deformed in contact with the tooth surface.
[0308] FIG. 29c illustrates, for example, by ejecting fluid from pressure chamber 635, or By reducing the amount of fluid in the pressure chamber 635, 1 illustrates a third operational state of mouthpiece 700 when the pressure therein is reduced. As can be seen in FIG. 29c, the flexible recesses result in a reduced pressure. The wall 623 is expanded, so to speak, to enlarge the recess 622, as compared to FIG. 29a. This allows the bristles 624 (particularly their free ends) to firmly engage with the tooth surfaces. (or does not engage with the tooth surface at all) and / or is deformed by contact with the tooth surface. It will no longer be possible to do so.
[0309] From a first operating state to a second operating state, and then from the second operating state to the first operating state , and then the pressure in the pressure chamber 635 is increased to go from the first operating state to the third operating state. This is followed by a return to the first operating state by appropriate cycles of increasing and decreasing the By repeating this cycle, the most effective use of the mouthpiece can be achieved. A smooth brushing action can be obtained. 24 generally performs upward and downward movements during such cycles, and recesses The bristles 624 at the wall legs 633 typically rotate during such a cycle as shown in FIG. 7, perform a lateral movement back and forth in the direction of the x-axis. When the pressure is increased and decreased reciprocally, the recess 622 alternately narrows and widens. Due to this, the bristles 624 at the recess wall foot are also as defined in FIG. The device will be subjected to pivoting back and forth about the z-axis as shown in FIG. This results in a sweeping movement of the bristles in the direction of the y-axis as defined by To make.
[0310] In the operating state (reduced pressure state) of FIG. 29c, the pressure in pressure chamber 635 is It should be noted that the pressure can be a vacuum, i.e., a pressure lower than atmospheric pressure. In the operating state of FIG. 29c (increased pressure state), the pressure in the vacuum chamber The force is a vacuum (e.g., 0.7 bar) and the pressure in the pressure chamber 635 is The operating conditions of 9b are either vacuum, atmospheric pressure, or pressure higher than atmospheric pressure. Additionally, in the operating states of Figs. 29b and 29c, the pressure channel It is also possible that the pressure inside both chambers is higher than atmospheric pressure. Alternatively, in the operating state of FIG. 29b, the pressure in the pressure chamber is approximately atmospheric pressure. On the other hand, in the operating state of FIG. 29c, the pressure in the pressure chamber is higher than the atmospheric pressure. It is noted that it is also possible that
[0311] As an example only to give some indication of the dimensions, and referring to FIG. For reference, for an adult, the width of the tooth element in the X direction is approximately It varies between 2mm and 12mm. It is desirable to keep the mouthpiece as small as possible. Taking into account that the recess wall is to be inserted into the cavity, the internal width of the U-shape of the recess wall in the X-direction should be as small as possible. should be kept small enough that it is approximately 0 to 4 mm wider than the width of each tooth. As an example to give some indication of the dimensions, The internal width of the U-shaped part wall is in the range of 0 mm to 20 mm when viewed in the X direction of Figure 27. The thickness can be in the range of, for example, 2 mm to 12 mm. The spool can be up to 6 mm long. The stem is 3 to 4 mm long, which is formed from the opposing recess wall legs 633. There should be no gaps between the bristles extending from the brush, or the gap should be about 2mm to 4mm. This means that there is a limited amount of space remaining. The gaps are shown exaggerated. As an example, the U-shape of the recess wall is in the range of 3 mm to 20 mm when viewed in the Y direction of FIG. For example, the inner height may range from 5 mm to 10 mm. These internal width and internal height measurements are given for adults. For different individuals or animals, these measurements may vary.
[0312] FIG. 30 shows a schematic top view of a third embodiment 710 of a mouthpiece according to the invention of Chapter 3. 31a, 31b, and 31c are diagrams showing the arrows XXX-X in FIG. XX shows schematic cross-sectional views of a mouthpiece 710 in its different operating states; The cross-sectional view is shown generally along the longitudinal axis Z of the dental arch as defined in FIG. It is possible that the values of the sigma-based ...
[0313] Mouthpiece 710 of FIGS. 30-31 is very similar to mouthpiece 700 of FIG. Taking into account that the same method has been used in connection with Figs. 28-29, The same reference numbers are used for the same or similar parts of mouthpiece 710.
[0314] Between the mouthpiece 700 of FIG. 29 and the mouthpiece 710 of FIGS. There are two differences in the following: Each of these differences applies to the other. 28 and / or 29 separately without the need for a separate application of the adhesive.
[0315] The first difference is that the mouthpiece of Figures 30-31 has five pressure chambers 635a, 63 5b, 635c, 635d, and 635e. In this case, pressure chambers 635a, 635c, and 635e are indicated by the shaded gray areas. As can be seen in Figure 30, the nipple 626 has a channel 637a for providing fluid communication with an external pressure source. This channel 637a flows into pressure chambers 635c and 635a. (Not shown in FIG. 30). Channel 637b connects pressure chambers 635c and 63 5a is connected to pressure chamber 635e, providing fluid communication between these chambers. Channel 637c connects pressure chamber 635e to pressure chambers 635a and 635b. 5b, providing fluid communication between these chambers. All pressure chambers 635a, 635b, 635c, 635d, and 635e are connected to each other. 6, which are in fluid communication with the pressure chamber 635 of the mouthpiece 700. The pressure chamber can be made to function as one single pressure chamber. 9b, and similar to that described in connection with FIG. 29c, and mouthpiece 71 0 has three operating states, or two if one can be omitted. In the description of the operating states shown in Figures 31a, 31b, and 31c, In this regard, reference is made to the explanations of Figures 29a, 29b and 29c.
[0316] The second difference is that the mouthpiece of Figures 30-31 has a slightly different support structure. The tongue plate 630 and the face plate 6 32 is embedded inside the body as in the case of mouthpiece 700. The tongue plate 630 of the mouthpiece 710 is disposed on the outer side of the main body 621. and face plate 632, both of which are curved along the zy plane defined in FIG. 30 and 31, which result in a U-shape when viewed along the z-axis. In one embodiment, the lingual plate 630 and the facial plate 632 are The recess wall bottoms 6 may be maintained at a predetermined distance from each other by a sensor (not shown). It is also possible that 34 can serve as such a spacer.
[0317] 32 to 35, the local deformation of the recess wall according to the first embodiment of the present invention in Chapter 3 is shown. Possibilities for implementing the invention will now be described, as well as the second aspect of the invention in Chapter 3. It will be possible.
[0318] Up to now, the overall deformability of the recess wall 623 has been described with reference to Figs. 27 to 31. The overall deformability is determined by the bristles 624 or the At least one pressure tuft 629 is attached to the recess wall 623. This occurs upon actuation of chamber 635. However, according to the first aspect of the invention in Chapter 3: The recess wall 623 is further configured to have local deformability. This local deformability of 3 is now shown in Figs. 32a, 32b, 32c and 32d. This will be explained with reference to d.
[0319] Figure 32a and Figure 32b are essentially the same. The difference is that in Figure 32b, one Although only tuft 629 is shown for illustrative purposes, in FIG. 32a, multiple tufts 62 This means that 9 is shown.
[0320] 32a and 32b show a dental arch 601 and a flexible recess on the facial side of the dental arch 601. 6 shows a flexible recessed wall leg 633 of the wall 623. The portion 633 is locally deformable.
[0321] These figures 32a and 32b are for illustrative purposes only, so the dental arch 601 the remainder of the recess wall leg 633 extending along the facial side of the dental arch 601, and the remainder of the recess wall leg 633 extending along the lingual side of the dental arch 601. A recess wall leg 633 and a recess wall bottom extending along the occlusal surface and optionally the incisal edge. 634 are not shown. Also, these unillustrated parts of the recess wall 623 are all localized. The shape of the slit may be configured to have various deformability.
[0322] 32a and 32b show the effect of increasing and decreasing the pressure in the pressure chamber. The local deformability of the flexible recess wall 623, in particular the local deformation of the recess wall leg 633, As can be seen, the recess wall legs 633 are deformable along the z-axis. 601 has an irregular shape due to the irregularity of the dental position of the dental arch 601. For purposes of illustration, the irregular shape of recess wall leg 633 may be 633 corresponds almost exactly to the irregular shape of the adjacent dental arch 601. The irregular shape of the recess wall leg 633 is smaller than the irregular shape of the dental arch 601 so that It is possible that the relationship between the two is not very clear.
[0323] 32a and 32b show recess wall leg 633 in an increased pressure state. As shown in Figures 32a and 32b, the main direction of pressure on the recess wall leg 633 is When the pressure is reduced, the recess wall legs 633 move toward the dental arch 60. 1, decreasing the pressure exerted by tuft 629 on tooth 640. When the pressure on the recess wall leg 633 is increased again, the recess wall leg 633 moves in a direction perpendicular to the tooth. This alternating movement in the direction of the x-axis is described in Chapter 3 of the present invention. This is the first dimension of the brushing movement realised by the mouthpiece.
[0324] When the pressure on the flexible recess wall leg 633 is to be reduced, the flexible recess wall leg 6 33 will not only move away from the dental arch 601 but may also be locally deformed. Due to the possibility that the flexible recess wall legs 633 may be less flexible under reduced pressure conditions. This also means that the shape tends to return to an unbroken, irregular shape. Irregular shapes that do not allow the flexible wall parts to move far enough away from the dental arch can be a continuously curved shape parallel to the z-axis, or still It is possible for the shape to have a relief, but at a higher pressure than in the increased pressure state. The shape of the recess wall 623 / recess wall foot 633 can be made with less relief. This local change in Rotating the stylus 629 around the y-axis results in a sweep in the z-direction along the facial surface of the tooth. When the pressure on the flexible recess wall legs 633 is increased, The lid 629 will tend to return to the position shown in Figures 32a and 32b. resulting in a sweep in the opposite z-direction along the facial surface of the tooth. This alternating sweeping movement in the direction of the z-axis (this sweep is shown in Figures 32a and 32b) (indicated by the double-headed arrow 641 in b) is the local deformation of the flexible wall part. The black feature is realized by the mouthpiece of the present invention described in Chapter 3. This is the second dimension of the singular movement.
[0325] The z-directional sweeping movement 641 about the y-axis moves the dental arch 60 in the z-axis direction. 1 local irregularity, and (local irregularity) when increasing and decreasing pressure. It is caused by local deformation of the flexible wall part (at the location of the wall).
[0326] Irregularities in the dental arch 601 in the direction of the y-axis y, as shown diagrammatically in FIG. And the local deformability of the flexible recess wall leg 633 of the flexible recess wall 623 is Similarly, when increasing and decreasing the pressure in the pressure chamber 635, the tuft 629 is moved z This means that the object will be swept in the y direction around the z axis. The alternating sweeping movement of the This is due to the local deformability of the flexible wall components, as explained in Chapter 3. It is this third dimension of brushing movement that is realised by the mouthpiece according to the invention.
[0327] Referring to FIG. 32d, the local deformability of the recess wall, taken together, is At the very least, additional two-dimensional brassinary structures, such as those shown in Fig. 32d by cone 643, may be used. This additional two-dimensional brushing action is This is in addition to the brushing action already caused by the pulsating pressure. The primary brushing action caused by the brush is indicated in FIG. 32d by the double-headed arrow 644. 28-31. Arrow 644 indicates the third dimension. Therefore, the overall brushing action at location L in FIG. 32d is , a three-dimensional brushing action: the bristles pivot back and forth around the y-axis, and the z-axis The bristles pivot back and forth around the x-axis, and the bristles are aligned back and forth along the x-axis. As will become clear, the local deformability of the recess wall leg 633 on the lingual side and And the local deformability of the recess wall bottom 634 may be used in a similar manner to provide additional two-dimensional blanking. This results in a squashing effect.
[0328] More generally, and at random bristle base 649 locations, additional The two-dimensional brushing action is achieved by a first reciprocating and pivoting movement of the bristles and a second reciprocating and pivoting movement of the bristles. and a second reciprocating and pivoting movement of the shaft, the two reciprocating and pivoting movements being Add to that a third reciprocating translational movement caused by pressure pulsations in the chamber With reference to the system of orthogonal axes as shown in FIG. At the location of the base of the bristles, the base of each random bristle is curved along the z axis. The bristles lie in the xy plane perpendicular to the If we call the xy plane in which the bristles are moving the bristle, the bristle root is moved in the xy plane. The translation of the two axes is in this local xy plane and is therefore perpendicular to the z axis. The recess wall is arranged in the local xy plane as follows, corresponding to the U-shaped cross section of the recess: Taking into account that it has an essentially U-shape, this reciprocating translational movement is In addition, in this local xy plane, it is approximately perpendicular to the U-shape of the recess wall. The first reciprocating pivoting movement is z at the base of each bristle at location L. about an axis, i.e., about a first pivot axis perpendicular to the local xy plane The second reciprocating pivoting movement is about a second pivot axis, The second pivot axis is perpendicular to the first pivot axis (or z-axis), and the third pivot axis is perpendicular to the first pivot axis (or z-axis). The reciprocating translational movement of the brush is perpendicular to the brush. In general terms, the local deformability of the recess wall is When the pressure is increased and decreased reciprocally, and when the plurality of dental When including the position, each location of the recess wall is a first forward rotation about the first pivot axis. a reciprocating pivoting movement about a second pivot axis; and a second reciprocating pivoting movement about a translation axis. and a first pivot axis, a second pivot axis, and a second pivot axis. The axis and the translation axis are perpendicular to each other.
[0329] In addition to the first, second, and third reciprocating movements discussed above, the recess wall , and the fourth, fifth, and sixth pores, which can further contribute to the brushing action. It is noted that a reciprocating movement can be made possible. The fourt...
