Description

[Technical Field]

[0001] The present invention relates to a dental treatment aid. [Background technology]

[0002] Generally, a practitioner needs a person to assist him in performing a medical procedure. For example, during a dental procedure, a dentist holds a speculum in one hand and a handpiece in the other, while an assistant holds a suction tool and positions a suction nozzle at the appropriate time and place to assist the procedure.

[0003] Such auxiliary work can be considered relatively simple and repetitive work, and as the trend of disliking simple and repetitive work becomes more severe, the need for technology that can replace humans is being raised.

[0004] On the other hand, devices that retract soft tissues such as lips have been used to ensure the dentist's field of vision, but this has the problem of causing discomfort to the patient. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Korean Patent Publication No. 2009-0128048 [Patent Document 2] US Patent Application Publication No. 2007 / 0148619 Summary of the Invention [Problem to be solved by the invention]

[0006] An object of one aspect of the present invention is to provide a dental treatment aid that can assist a practitioner during a dental treatment while reducing discomfort to a patient.

[0007] Another aspect of the present invention is to provide a dental treatment aid that is worn by a patient during dental treatment to assist in the positioning of a treatment tool such as a suction tip while allowing the patient to perform opening and closing procedures. [Means for solving the problem]

[0008] A dental treatment auxiliary device according to one embodiment of the present invention includes an inner frame inserted into the oral cavity and a retraction member coupled to the inner frame to retract surrounding tissues of the oral cavity, and may further include a holder provided on at least one of the inner frame and the retraction member to fix a suction, so that one side of the suction is positioned at a predetermined location in the oral cavity.

[0009] In this case, the holder may be provided movably or detachably on the inner frame or the towing member.

[0010] The suction device preferably includes a suction tip and a suction tube, and the suction tube preferably has a flexural modulus within a range of 0.3 to 2.8 Gpa.

[0011] The inner frame and the traction member may have a shape that is symmetrical both vertically and horizontally.

[0012] It is also preferable that the holder fixes the suction so that the end of the suction is positioned between the oral vestibule and the buccal mucosa.

[0013] Also, beforeThe internal frame comprises a first region that contacts the area around the frenum in the oral cavity, a second region that contacts the area around the buccal mucosa, and a third region that is located between the first and second regions and contacts the area around the oral vestibule. The first region may be provided with a dimple suppression that is shaped to be pulled toward the center of the oral cavity, so that the frenum can be brought close to the dimple suppression when the internal frame is inserted into the oral cavity.

[0014] It is also preferable that there is a predetermined height difference between the highest point of the first area and the lowest point of the second area.

[0015] Preferably, the second section is extended laterally, and the third section has a curved shape whose absolute value of the slope decreases from the first section to the second section.

[0016] Also, before The retraction member includes an outer frame that can be attached to the outside of the oral cavity; and a cover member that is formed in the shape of an elastic film and has one side connected to the inner frame and the other side connected to the outer frame, thereby enabling the patient's oral cavity to be kept open while performing a mouth-opening process in which the gap between the upper and lower teeth is widened and a mouth-closing process in which the gap between the upper and lower teeth is narrowed.

[0017] In this case, the holder is movably provided on the inner frame or the traction member so that the suction is positioned at a first position corresponding to the anatomical shape of the oral cavity and the treatment situation, and the first position means a position where the suction operation can be performed without interfering with the treatment.

[0018] Preferably, the suction includes a suction tip and a suction tube, and the force required to separate the suction tube from the holder is greater than the force required to fix the suction tube to the holder.

[0019] It is also preferable that the holder is provided on the inner frame, an outer holder is provided on the outer frame, and the suction tube is fixed to the holder and the outer holder.

[0020] Furthermore, it is preferable that the internal frame comprises a first region that contacts the area around the frenum in the oral cavity, a second region that contacts the area around the buccal mucosa, and a third region that is located between the first and second regions and contacts the area around the oral vestibule, and that there is a predetermined height difference between the highest point of the first region and the lowest point of the second region, and that the surface that includes the closed or open curve that constitutes the internal frame is a curved surface.

[0021] Also, the second section may be extended laterally, and the inner frame may be recessed to have a peanut shape, with the portion of the inner frame that contacts the frenulum area in the oral cavity being recessed. [Effects of the Invention]

[0022] According to one embodiment of the present invention, not only can a practitioner perform treatment alone without the assistance of an assistant, but it can also provide useful effects such as improving the practitioner's convenience in treatment and reducing the patient's discomfort.

[0023] In addition, since the treatment tool can be fixed in an optimal position that does not interfere with the practitioner's treatment when performing various types of treatment, interference with the movement of handpieces, instruments, etc. operated by the practitioner can be minimized.

[0024] Furthermore, by making the internal frame have an ergonomic shape that corresponds to the internal structures of the oral cavity, such as the frenulum, the internal frame can be attached inside the oral cavity while reducing discomfort to the patient.

[0028] A dental treatment auxiliary tool 1000 according to an embodiment of the present invention may include an outer frame 100 , an inner frame 200 , a cover member 300 and a holder 240 .

[0029] 14, a dental treatment auxiliary instrument may be realized by combining first to fourth retraction members 410, 420, 430, and 440 with an inner frame 200-1 and providing a holder 240. In this case, the inner frame 200-1 is positioned in the oral cavity, and the first to fourth retraction members 410, 420, 430, and 440 are connected to the inner frame 200-1 to retract soft tissues such as lips.

[0030] Meanwhile, the cover member 300 and the outer frame 100 may be referred to as retraction members because they perform the function of retracting soft tissues such as lips. That is, the cover member 300 and the outer frame 100 are connected to the inner frame 200 as retraction members, and can retract lips, etc. In addition, the dental treatment assist device 1000 can withstand the muscular strength of soft tissues around the oral cavity and can be closely attached to the inside of the oral cavity. As a result, the dental treatment assist device 1000 can be closely attached to the anatomical structures within the oral cavity and can be used in various treatment procedures such as orthodontics, prosthetics, periodontal treatment, and surgical procedures.

[0031] In one embodiment, the inner frame 200 and the outer frame 100 may have a closed curved shape or a linear or curved shape with at least a portion open. In one embodiment, the cover member 300 is connected between the inner frame 200 and the outer frame 100.

[0032] In one embodiment, the inner frame 200 and the outer frame 100 may be made of various materials capable of retracting soft tissue. For example, the inner frame 200 and the outer frame 100 may be made of various metals or synthetic resin materials.

[0033] In one embodiment, the cover member 300 has elasticity and may be in the form of a film, while in other embodiments, the cover member 300 may be made of various synthetic resins or various metal materials.

[0034] In one embodiment, one side of the cover member 300 is coupled to the inner frame 200, and the other side of the cover member 300 is coupled to the outer frame 100. Accordingly, a hollow pillar shape can be realized, with the bottom edge being the inner frame 200, the top edge being the outer frame 100, and the sides being the cover member 300. The inner frame 200 can be installed to be positioned inside the patient's oral cavity, and the outer frame 100 can be installed to be positioned outside the patient's lips, so that the practitioner's field of view of the affected area can be secured by retracting soft tissue such as the patient's lips.

[0035] In one embodiment, the dental treatment auxiliary tool 1000 is provided with a holder 240. The holder 240 may be provided on the inner frame 200 or the outer frame 100. A treatment tool such as a suction tip 510 may be fixed to the holder 240. Accordingly, the dental treatment auxiliary tool 1000 according to one embodiment of the present invention may realize the effect of enabling traction of the affected area and fixation of the treatment tool.

[0036] In one embodiment, the holder 240 may be provided to be movable or deformable. In one embodiment, the holder 240 may be made of an elastic material. In one embodiment, the holder 240 may position the suction 500 at a predetermined position corresponding to the anatomical shape of the oral cavity and the treatment situation. In this case, the predetermined position may refer to a position where the suction operation can be performed without the suction 500 interfering with the treatment. As a result, the suction 500 can be positioned at a position that matches the patient's anatomical shape, thereby reducing patient discomfort. In addition, the suction 500 may be positioned at a first position during a certain treatment and at a second position during another treatment.

[0037] In one embodiment, the holder 240 may be embodied as a fixed type. Once the inner frame 200 is fixedly positioned in the oral cavity, the position of the holder 240 may be adjusted. At this time, the position where the treatment tool should be positioned inside the oral cavity may be determined as the fixed position depending on conditions such as the type of treatment tool fixed to the holder 240 and the treatment site, and the position that can support the treatment tool to be positioned at the fixed position thus determined may be understood as the fixed position of the holder 240.

[0038] In one embodiment, the fixed position of the surgical tool may refer to a position of the surgical tool in which the end of the surgical tool contacts any one point in the space between the oral vestibule (the gum trough) and the buccal mucosa.

[0039] In another embodiment, the holder 240 may be embodied to be variable in position. In this case, the position of the holder 240 may be varied by sliding along the inner frame 200, the outer frame 100, and the cover member 300. The holder 240 may also be detachable from the inner frame 200, the outer frame 100, and the cover member 300.

[0040] In one embodiment, it is preferable that at least a portion of the holder 240 is made of an elastic material. The holder 240 may be shaped like tweezers or may be annular and form a closed curve. In one embodiment, the holder 240 alone may form the closed curve, but in other embodiments, the holder 240 may form the closed curve together with the inner frame 200 (see 240-1 in FIG. 6). As illustrated in FIGS. 7 to 11, the holder 240 may have various shapes, and the coupling relationship with the inner frame 200 may be appropriately selected depending on the shape (see 240-2, 240-3, 240-4, 240-5, 240-6, 240-7, 240-8, 240-9, 240-10, and 240-11 in FIGS. 7 to 11). In one embodiment, although not shown, the holders 240, 240-1, 240-2, 240-3, 240-4, 240-5, 240-6, 240-7, 240-8, 240-9, 240-10, and 240-11 may be provided on the external frame 100 separately from the external holder 120 and used to secure surgical tools.

[0041] 3, in one embodiment, the inner frame 200 may include a first region 210, a second region 220, and a third region 230. Here, the first region 210 may refer to the portion of the inner frame 200 that contacts the area around the frenum in the oral cavity, the second region 220 may refer to the portion that contacts the area around the buccal mucosa in the oral cavity, and the third region 230 may refer to the portion that is located between the first region 210 and the second region 220 and that contacts the area around the oral vestibule.

[0042] In one embodiment, the first region 210 may have a recess 211. The recess 211 may be shaped so that at least a portion of the first region 210 is retracted toward the center of the oral cavity. Accordingly, when the internal frame 200 is inserted into the oral cavity, the frenulum approaches the recess 211 (dimple suppression), allowing the first region 210 to contact the area around the frenulum. Conventional retractors have had problems such as excessive pressure on the frenulum area, causing discomfort to the patient, or the internal frame 200 not being stably fixed in the oral cavity, causing the internal frame 200 to slip out of the oral cavity even with small movements. In the present invention, the first region 210 has a shape that corresponds to the area around the frenulum, thereby alleviating discomfort and allowing the internal frame 200 to be stably positioned in the oral cavity.

[0043] In one embodiment, there may be a predetermined height difference H1 between the central end 112 and the lateral end 111. In other words, the surface of the external frame 100 that includes a closed or open curve may be curved.

[0044] In one embodiment, there may be a predetermined height difference H2 between the highest point of the first section 210 and the lowest point of the second section 220. In other words, the surface including the closed or open curve that forms the internal frame 200 may be curved.

[0045] In this way, since the internal frame 200 has a three-dimensional shape, it is possible to reduce discomfort to the patient while allowing the internal frame 200 to be stably positioned in the oral cavity.

[0046] In one embodiment, the second section 220 is preferably extended laterally, and the third section 230 is preferably formed into a curved shape whose absolute value of slope decreases from the first section 210 to the second section 220. Accordingly, by pushing the patient's cheek out as much as possible, sufficient field of view and space are secured even when treating the back teeth, and treatment tools such as the suction tip 510 fixed by the holder 240 are fixed in an optimal position (where liquid such as water collects), allowing for efficient suction work without interfering with the movement of other treatment tools such as handpieces. In addition, the shape is adapted to the anatomical shape of the soft tissue inside the cheek, thereby reducing patient discomfort, and allowing the internal frame 200 to exert a stable traction force, thereby enabling treatment tools such as the suction tip 510 to be stably fixed.

[0047] In one embodiment, the inner frame 200 and the outer frame 100 may be configured to be asymmetrical depending on the intraoral anatomy.

[0048] In another embodiment, the inner frame 200 and the outer frame 100 may be formed symmetrically in the vertical and horizontal directions. In this case, even if the outer holder 120 is located only on either the upper or lower side of the outer frame 100, the outer holder 120 can be positioned where needed by rotating the dental treatment aid 1000 180 degrees and arranging it upside down. In this way, the outer holder 120 provided on the outer frame 100 can reduce the degree to which the practitioner's treatment is hindered.

[0049] In one embodiment, at least one of the internal frame 200 and the external frame 100 may be formed to be asymmetrical vertically or horizontally depending on the patient, such as a pediatric patient or a disabled patient, and in this case, additional positions for the holders 240 may be provided.

[0050] In one embodiment, the holder 240 may fix the surgical tool so that it is positioned in the space between the oral vestibule and the buccal mucosa. In one embodiment, the holder 240 determines the position of the surgical tool, but may also fix the surgical tool so that it is positioned in the space between the oral vestibule and the buccal mucosa. As a result, the surgical tool does not interfere with the practitioner's treatment, and discomfort to the patient may be minimized. In this case, the position of the holder 240 on the inner frame 200 or the position of the outer holder 120 on the outer frame 100 may be determined depending on the structure of the holder 240 and the coupling relationship between the holder 240 and the surgical tool.

[0051] Referring to FIG. 4, it will be understood that the suction 500 as a treatment tool is coupled to the dental treatment auxiliary instrument 2000 and used in treatment.

[0052] 2 and 5 illustrate an embodiment in which the external frame 100 is provided with an external holder 120. As illustrated in FIG. 2, the external holder 120 may protrude horizontally from the external frame body 110, or as illustrated in FIG. 5, the external holder 120 may protrude in a direction having a predetermined inclination with respect to the horizontal direction.

[0053] 12 and 13, the inner frame 200 may be oval or peanut shaped to fit the shape of the oral cavity, which may improve manufacturing efficiency.

[0054] In yet another embodiment, the inner frame 200 may be embodied as a closed curve with a partially concave / convex shape or a closed curve with an open structure for easy and stable attachment to the oral cavity. In one embodiment, if the inner frame 200 and the outer frame 100 are formed in a flat or nearly flat shape, manufacturing efficiency may be improved.

[0055] FIG. 15 is a view for explaining a dental treatment auxiliary tool 3000 according to an embodiment of the present invention.

[0056] 15, the dental treatment assisting device 3000 according to an embodiment of the present invention can retract soft tissues around the oral cavity and also suck and remove liquids such as saliva and water that accumulate in the oral cavity during dental treatment. In this case, the suction 500 can be composed of a suction tip 510 and a suction tube 520.

[0057] In one embodiment, a suction tip 510 may be connected to one end of a suction tube 520, and a connector 600 may be connected to the other end of the suction tube 520. A suction line 700 may be connected between an inhalation means 800, such as a suction pump, and the connector 600. Accordingly, a suction force generated by the inhalation means 800 may be provided to the suction tube 520 via the suction line 700 and the connector 600.

[0058] In one embodiment, it is preferable to have a greater force required to separate the suction tube 520 from the holder 240 than is required to secure the suction tube 520 to the holder 240. It is also preferable to have the suction tube 520 not separate from the holder 240 when an instrument manipulation or soft tissue force is applied to the suction tube 520.

[0059] In one embodiment, the connector 600 may be provided with an adjustment device 610. The adjustment device 610 may adjust whether the suction tube 520 and the suction line 700 are open or closed. As illustrated in FIG. 15 , multiple suction tubes 520 may be connected to the connector 600, and the adjustment device 610 may adjust whether or not suction force is provided to each or all of the suction tubes 520. In one embodiment, the connector 600 may be located on the chest or abdomen of the patient, allowing the practitioner to easily adjust whether or not suction force is provided to the suction tubes 520. Meanwhile, the suction means 800 and the suction line 700 may be implemented with a suction pump and suction line that are included in most existing dental chairs. Therefore, by connecting an existing suction line to the connector 600, the dental procedure assistant according to one embodiment of the present invention can be used. As a result, there is no need to replace the dental chair, and unnecessary costs involved in introducing the dental procedure assistant can be minimized.

[0060] In one embodiment, the suction tube 520 may be embodied as a tube having an inner diameter of 3 to 6 mm, an outer diameter of 4 to 7 mm, and a thickness of 0.2 to 1.5 mm. In one embodiment, the length of the suction tube 520 from the portion contacting the holder 240 provided on the inner frame 200 to the section contacting the holder provided on the outer frame 100 may be approximately 20 to 150 mm.

[0061] <Experimental Example 1> A sample is prepared by inserting a suction tube 520 having an inner diameter of 3 mm, an outer diameter of 4 mm, and a thickness of 0.5 mm into the holder illustrated in FIG. The suction tube 520 is prepared with different flexural modulus for each sample. After placing the prepared sample in the oral cavity of an adult male, the number of times the mouth was opened and closed was counted until the suction tube 520 was released from the holder, and the discomfort experienced by the subject was assessed on a 10-point scale. The number of times that the suction tube 520 became clogged was investigated during the 5-minute scaling procedure with a suction force of 180 mbar.

[0062] [Table 1]

[0063] According to the experimental results, it can be confirmed that when the bending elastic modulus is less than 0.3 GPa, the maintaining force of the suction tube 520 is suddenly reduced, which makes it difficult for the suction tube 520 to recover its shape. As a result, the flow of fluid through the inside of the suction tube 520 becomes less smooth, and clogging phenomenon increases rapidly.

[0064] In addition, according to the experimental results, it was confirmed that when the bending elastic modulus exceeds 2.80 Gpa, the suction tube 520 fixed by the holder in the oral cavity is not stably fixed to the holder and may come off from the holder, causing a problem of sudden increase in discomfort during the opening and closing of the mouth of the patient.

[0065] Considering the above experimental results, it is preferable that the flexural modulus of the suction tube 520 is in the range of 0.3 to 2.8 GPa. Accordingly, when the patient repeats opening and closing the mouth while wearing the dental treatment assisting device 3000, the patient's discomfort is minimized, the risk of excessive change in the position of the suction tip 510 is reduced, the detachment of the suction tube 520 is minimized, and the retention force, operability, comfort, and adhesion of the suction tube 520 can be appropriately ensured.

[0066] In one embodiment, the suction tube 520 may be implemented as a pipe made of silicone, polyurethane, PVC, etc. If necessary, the suction tube 520 may be implemented with metal wire inserted as a reinforcing material to increase operability.

[0067] As illustrated in FIGS. 16 and 17 , the dental treatment assisting device 4000 may be formed integrally with the outer frame 100, the inner frame 200, and the cover member 300. In this case, the outer frame 100 may be made of a first material and a first thickness, the inner frame 200 may be made of a second material and a second thickness, and the cover member 300 may be made of a third material and a third thickness. Alternatively, the dental treatment assisting device 4000 may be manufactured by a double injection method, in which the outer frame 100 and the inner frame 200 are pre-fabricated and then placed in a mold to form the cover member 300. In one embodiment, a marker may be provided on the outer frame 100. A situation may arise in which the center of the dental treatment assisting device 4000 needs to be identified during the process of inserting the dental treatment assisting device 4000 into the oral cavity or during treatment. In such cases, a marker may be used. In one embodiment, the marker may be implemented as a color marking portion 151 that is a portion of the outer frame 100 divided into different colors. In another embodiment, the marker may be implemented as a protrusion 152 formed to protrude from the outer frame 100.

[0068] 18, the inner frame 200 side of the dental treatment auxiliary device 4000 can be inserted into the patient's oral cavity with the outer frame 100 positioned outside the lips. Next, the suction 500 can be positioned as needed and fixed using the holder 240. In this state, as shown in (b) and (c) of FIG. 18, the patient can perform an opening process to widen the gap between the upper and lower teeth, or a closing process to bring the upper and lower teeth into contact.

[0069] Although the representative embodiments of the present invention have been described above in detail, those skilled in the art will understand that various modifications can be made to the above-described embodiments without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the following claims as well as equivalents thereof. [Industrial Applicability]

[0070] The dental treatment assistant according to one embodiment of the present invention is a consumable item used during dental treatment, and therefore can be used in the fields of treatment and medicine, and in particular, can be used in industries to solve problems caused by a shortage of dental treatment assistants.
