Blocks, systems and methods for tooth stabilization

Abstract

One object of the present invention is to provide a tooth stabilization device that prevents patients from easily releasing their teeth from the device during dental surgery. To this end, the inventors have proposed a tooth stabilization block that includes internal channels opening onto the surface of the block that contacts the patient's teeth. These internal channels connect to an inlet through which a bite registration material, designed to harden and mold to the patient's teeth, can be injected. This makes it more difficult for the patient to release their teeth from the tooth stabilization block once the bite registration material has hardened and molded around the teeth.

[0053] It is an object of the present invention to provide a dental stabilization device that prevents patients from easily releasing their mouth from the device during dental procedures.

[0054] To this end, the inventors have proposed a dental stabilization block comprising internal channels that open on the face of the block that contacts the patient's teeth. These internal channels are connected to an inlet through which a bite registration material, intended to harden and be molded onto the patient's teeth, can be injected.

[0055] In this way, it becomes more difficult for the patient to release their teeth from the dental stabilisation block when the bite registration material has hardened and moulded around the teeth.

[0056] Therefore, if Figure 1 As shown, the present invention relates to a dental stabilization block 100 .

[0057] In practice, the dental stabilization block 100 is intended to be bitten between the patient's upper and lower molars and / or premolars (hereinafter "teeth") on only one side of the mouth.

[0058] In other words, when the dental stabilizer 100 is in place in the patient's mouth, the patient can bite the dental stabilizer 100 with only his or her upper molars and lower molars, or with only his or her upper premolars and lower premolars, or with his or her upper molars and lower molars and upper premolars and lower premolars.

[0059] In a preferred embodiment of the present invention, tooth stabilization blocks 100 of different sizes may be provided according to the patient's tooth morphology, ie, the arrangement of their teeth on the upper and lower jaws.

[0060] For example, a model for children and a model for adults may be provided.

[0061] However, other arrangements that take into account the patient's dental morphology may be envisioned as desired without requiring substantial modification of the present invention.

[0062] [ Figure 2 ] shows the dental stabilization block 100 when it is located on the lower teeth on the left side of the patient's mouth.

[0063] In fact, the tooth stabilization block 100 makes it possible to keep the patient's mouth open during dental procedures in order to prevent the teeth from meeting.

[0064] Thus, the dental stabilization block 100 allows access to teeth and gums located on opposite sides of the mouth and in the front of the mouth without being significantly obstructed by the dental stabilization block 100 .

[0065] In other words, when the dental stabilization block 100 is in place in the patient's mouth, the dental practitioner performing the procedure can access the teeth and gums located at the front of the mouth and the portion of the mouth located opposite the dental stabilization block 100 within the mouth.

[0066] Thus, in a first example, if the dental stabilization block 100 is positioned on a tooth located on the right side of the patient's mouth, the practitioner can access the teeth and gums disposed in the front of the mouth as well as the teeth disposed on the left side of the mouth.

[0067] Likewise, in the second example, if the dental stabilization block 100 is positioned on a tooth located on the left side of the patient's mouth, the practitioner can access the teeth and gums disposed in the front of the mouth as well as the teeth disposed on the right side of the mouth.

[0068] Returning to the present invention, the dental stabilization block 100 comprises a body 110 that is substantially parallelepiped-shaped.

[0069] Therefore, the main body 110 has a parallelepiped shape, that is, a six-sided polyhedron whose six faces are parallel in pairs.

[0070] In practice, the shape of the body 110 is substantially curved to accommodate the approximate curvature of the upper and lower teeth in a human jaw.

[0071] In particular, as [ Figure 1 ]、[ Figure 3 ]、[ Figure 7 ]and[ Figure 9 ] As shown in FIG, when the dental stabilization block 100 is in place in the patient's mouth, the main body 110 includes an upper wall 111, a lower wall 112, a first side wall 113, a second side wall 114, a front end wall 115 and a rear end wall 116.

[0072] In fact, the upper wall 111 has an upper outer fastening surface designed to come into contact with the upper teeth.

[0073] In a particular embodiment of the upper outer fastening surface, such as [ Figure 1 ]、[ Figure 3 ]、[ Figure 4 ]、[ Figure 5 ]、[ Figure 6 ]、[ Figure 7 ]and[ Figure 9 ] As shown in FIG, the upper outer fastening surface includes an upper edge 1111.

[0074] In particular, upper peripheral edge 1111 is configured to retain bite registration material as described below.

[0075] In a particular embodiment of the upper outer fastening surface, such as [ Figure 1 ]、[ Figure 3 ]、[ Figure 4 ]、[ Figure 5 ]、[ Figure 6 ]、[ Figure 7 ]and[ Figure 9 ] As shown in FIG, the upper outer fastening surface is provided with a plurality of fluid flow interference ribs 1112.

[0076] In practice, each fluid flow disruption rib 1112 is configured to cause a disruption in the flow of fluid across the upper outer fastening surface when the dental stabilization block 100 is in place in the patient's mouth.

[0077] In a first example of this particular embodiment, the fluid flow disrupting ribs 1112 extend from the upper outer fastening surface toward the top.

[0078] In a second example of this particular embodiment, the fluid flow disrupting rib 1112 extends through the fluid flow axis of the upper outer fastening surface.

[0079] In a third example of this particular embodiment, the fluid flow disrupting rib 1112 has an upper outer turbulent surface selected from the group consisting of: a stepped surface, a ridged surface, a dimple surface, or a roughened surface.

[0080] In addition, as [ Figure 1 ]、[ Figure 3 ]、[ Figure 4 ]and[ Figure 5 ] As shown, the upper outer fastening surface includes at least one first outlet opening 1113.

[0081] In one embodiment of the first outlet orifice 1113, as [ Figure 4 ] As shown in FIG, the first outlet orifice 1113 includes a peripheral inner recess 1113a so as to form at least a first peripheral separation surface, which is arranged below the upper outer fastening surface.

[0082] Similar to the upper wall 111 , the lower wall 112 has a lower outer fastening surface designed to contact the lower teeth.

[0083] In one embodiment of the lower outer fastening surface, the lower outer fastening surface is provided with a plurality of fluid flow disrupting ribs similar to the fluid flow disrupting ribs 1112 of the upper outer fastening surface.

[0084] In a first example of this particular embodiment, the fluid flow disrupting ribs extend downwardly from the lower outer fastening surface.

[0085] In a second example of this particular embodiment, the fluid flow disrupting rib extends through the fluid flow axis of the lower outer fastening surface.

[0086] In a third example of this particular embodiment, the fluid flow disrupting rib has a lower outer turbulent surface selected from the group consisting of: a stepped surface, a ridged surface, a dimple surface, or a roughened surface.

[0087] Furthermore, the lower outer fastening surface comprises at least one second outlet aperture 1123 .

[0088] like[ Figure 5 ] As shown in FIG, similar to the first outlet orifice 1113, in a specific embodiment of the second outlet orifice 1123, the second outlet orifice 1123 includes a peripheral internal recess to form at least a second peripheral separation surface, which is arranged below the lower outer fastening surface.

[0089] like[ Figure 2 ], about [ Figure 1 ]、[ Figure 3 ]、[ Figure 4 ]、[ Figure 5 ]、[ Figure 6 ]、[ Figure 7 ]and[ Figure 9 ], when the tooth stabilization block 100 is in place in the patient's mouth:

[0090] - a first side wall 113 oriented towards the interior of the oral cavity,

[0091] The second side wall 114 is oriented toward the inner cheek surface, particularly toward the inner cheek surface on the side of the mouth where the dental stabilization block 100 is installed. Thus, if the dental stabilization block 100 is installed on the right side of the patient's mouth, the second side wall 114 is oriented toward the inner surface of the patient's right cheek. Furthermore, if the dental stabilization block 100 is installed on the left side of the patient's mouth, the second side wall 114 is oriented toward the inner surface of the patient's left cheek.

[0092] - the front end wall 115 is oriented towards the front of the oral cavity, and

[0093] - The rear end wall 116 is oriented towards the back of the oral cavity.

[0094] In addition, as [ Figure 5] As shown in FIG, the main body 110 includes at least a first internal channel 117, at least a second internal channel 118 and a first internal joining area 119.

[0095] In particular, the first internal channel 117 located inside the body 110 opens towards the outside of the body 110 at the level of at least the first outlet orifice 1113 and / or at least the second outlet orifice 1123 .

[0096] In other words, the first internal passage 117 may open toward the exterior by passing through only the first outlet aperture 1113 , or by passing through only the second outlet aperture 1123 , or by passing through both the first outlet aperture 1113 and the second outlet aperture 1123 .

[0097] Furthermore, the first internal passageway 117 defines a flow path configured to be passed through by a bite registration material that is intended to at least harden and be molded onto the teeth.

[0098] In a first embodiment of the bite registration material, the bite registration material is selected from wax.

[0099] For example, it can be selected from mineral waxes (e.g. alkanes such as paraffin wax), waxes of natural origin (e.g. esters such as carnauba wax, beeswax), waxes of synthetic origin (e.g. polyethylene wax, polyethylene glycol wax, hydrogenated or halogenated hydrocarbon waxes) and any combination thereof.

[0100] In a second embodiment of the bite registration material, the bite registration material is selected from zinc oxide-eugenol paste.

[0101] In a third embodiment of the bite registration material, the bite registration material is selected from addition silicone elastomers.

[0102] In a fourth embodiment of the bite registration material, the bite registration material is selected from polyester elastomers.

[0103] However, as required, it is conceivable to use other dental materials which are capable of deforming under occlusal stress, registering this deformation and recovering this deformation without modification, without substantial modification of the invention.

[0104] The second internal channel 118 located inside the body 110 opens towards the outside of the body 110 at the level of the inlet orifice 1131 .

[0105] The inlet aperture 1131 is configured to receive at least an end portion of a device for injecting bite registration material.

[0106] In one example, the end portion according to the invention is a mixing tip of a bite registration syringe of known type.

[0107] In one embodiment of the inlet orifice 1131, as [ Figure 5 ]and[ Figure 8 ] As shown in FIG. 1 , the inlet orifice 1131 includes a shoulder 1132 against which the end of the device for injecting bite registration material can rest.

[0108] Furthermore, in the present invention, the inlet opening 1131 is provided on the outer surface of the first side wall 113 and / or the front end wall 115 .

[0109] In other words, the inlet opening 1131 may be provided only on the outer surface of the first side wall 113 , or only on the outer surface of the front end wall 115 , or on both the outer surfaces of the first side wall 113 and the front end wall 115 .

[0110] Finally, the first interior joining region 119 is configured to establish fluid communication between the first interior passage 117 and the second interior passage 118 .

[0111] Thus, when the snap-in material is injected into the inlet aperture 1131 , the snap-in material may come out at the level of the outlet apertures 1113 , 1123 .

[0112] [ Figure 5 ] shows outlet openings 1113, 1123.

[0113] In a first manner of implementing the present invention, the body 110 includes a plurality of first internal channels 117 and a plurality of second internal joining areas.

[0114] In practice, the plurality of first internal channels 117 within the body 110 are arranged such that, in response to injection of bite registration material, the bite registration material appears substantially simultaneously at the level of the outlet apertures 1113 , 1123 .

[0115] Furthermore, the plurality of second internal joining regions are arranged such that each second internal joining region establishes fluid communication between at least two first internal channels 117 .

[0116] In other words, each second internal joining region may establish a fluid connection between two, three, four, or more than four first internal channels 117 .

[0117] In a second manner of implementing the present invention, the first side wall 113 and the second side wall 114 are designed to extend beyond the upper outer fastening surface and / or the lower outer fastening surface toward the top and / or bottom of the oral cavity, respectively.

[0118] In other words, in the second way of implementing the present invention, the first side wall 113 and the second side wall 114 either extend only toward the roof of the mouth, or extend only toward the bottom of the mouth, or extend toward both the roof and the bottom of the mouth.

[0119] This arrangement allows the dental stabilization block 100 to cover the upper teeth and / or lower teeth when it is in place in the patient's mouth so as to form an upper enclosure and / or lower enclosure of U-shaped cross-section, in which the bite registration material and the upper teeth and / or lower teeth can be retained.

[0120] In other words, when the first side wall 113 and the second side wall 114 extend only toward the roof of the mouth, they form an upper enclosure. Additionally, when the first side wall 113 and the second side wall 114 extend only toward the floor of the mouth, they form a lower enclosure. Finally, when the first side wall 113 and the second side wall 114 extend toward both the roof and the floor of the mouth, they form both an upper enclosure and a lower enclosure.

[0121] In particular, as [ Figure 6 ] As shown in the upper enclosure 1114 and the lower enclosure, the base of the U-shaped portion of the upper enclosure 1114 or the lower enclosure includes an upper outer fastening surface or a lower outer fastening surface, respectively.

[0122] Furthermore, the wings of the U-shaped portion of the upper enclosure 1114 or the lower enclosure include a first side wall 113 and a second side wall 114 , respectively.

[0123] Thus, the upper enclosure 1114 has a U-shaped cross-section, the base of which comprises the upper outer fastening surface, and the wings of which comprise the first side wall 113 and the second side wall 114 .

[0124] Furthermore, similar to the upper enclosure 1114 , the lower enclosure has a U-shaped cross-section, the bottom of which includes a lower outer fastening surface, and the wings of which include a first side wall 113 and a second side wall 114 .

[0125] In a specific embodiment, as [ Figure 1 ]、[ Figure 3 ]、[ Figure 4 ]and[ Figure 6 ] As shown in FIG, the second side wall 114 extends higher than the first side wall 113.

[0126] In a third embodiment of the present invention, the second side wall 114 is provided with a cheek retractor portion 130 , which is used to retract the inner cheek surface of the second side wall 114 .

[0127] In particular, as [ Figure 1 ]、[ Figure 2 ]、[ Figure 3 ]、[ Figure 6 ]、[ Figure 7 ]、[ Figure 8 ]and[ Figure 9 ] As shown in FIG. 1 , the cheek retractor portion 130 protrudes from the second side wall 114 toward the inner cheek surface.

[0128] In addition, as [ Figure 7 ]and[ Figure 9 ] As shown in FIG, when the dental stabilization block 100 is in place in the patient's mouth, the cheek retractor portion 130 has an L-shape with a circular bend 131.

[0129] In practice, such as [ Figure 7 ]and[ Figure 9 ] As shown in FIG, one of the branches of the cheek retractor portion 130, hereinafter referred to as the "support branch" 132 and the circular curved portion 131 are supported on the inner cheek surface.

[0130] Furthermore, another branch of the cheek retractor portion 130 , hereinafter referred to as the “cantilever branch” 133 , is cantilevered and at least partially supported on the rear end wall 116 .

[0131] In the first embodiment of the third mode of implementing the present invention, as [ Figure 8 ] As shown in FIG, the cheek retractor portion 130 includes at least one third internal channel 134, which is at least partially disposed within the circular curved portion 131.

[0132] In the first embodiment of the first embodiment of the third way of carrying out the present invention, the internal passage 134 is provided in the circular bend 131 and in the support branch 132 .

[0133] In the second embodiment of the first embodiment of the third way of carrying out the present invention, the internal passage 134 is provided within the circular bend 131 and within the cantilever branch 133 .

[0134] In a third embodiment of the first embodiment of the third way of carrying out the invention, the internal passage 134 is provided within the circular bend 131 , within the support branch 132 , and within the cantilever branch 133 .

[0135] In practice, the third internal channel 134 opens towards the outside of the body of the support branch 132 at the level of the suction orifice 1341 and at the level of the discharge orifice 1342 .

[0136] In particular, as [ Figure 8 ] As shown in FIG, the suction orifice 1341 is arranged on the cantilever branch 133 upstream of the rear end wall 116 relative to the patient's mouth.

[0137] Furthermore, a discharge orifice 1342 is provided on the support branch 132 downstream of the suction orifice 1341 relative to the patient's mouth.

[0138] In a specific implementation of the first embodiment of the third mode of implementing the present invention, as [ Figure 8 ] As shown in FIG. 1 , the support branch 132 includes a suction sleeve guide portion 1321, which opens in the direction of the second side wall 114 and extends axially from the discharge orifice 1342 to the free end of the support branch 132.

[0139] In the second embodiment of the third mode of implementing the present invention, as [ Figure 9 ] As shown in FIG. 1 , the tooth stabilization block 100 further includes an extension branch 140, which extends obliquely or vertically from the free end of the supporting branch 132 toward the outside of the oral cavity.

[0140] In practice, the extension branches 140 are designed to form a direction-changing region 141 that presents an outer surface covering the labial commissure of the oral cavity when the extension branches 140 are deflected to exit the patient's oral cavity.

[0141] Furthermore, at least one free end region of the extension branch 140 comprises at least one supporting element 142 , 143 adapted to support at least one position reference element.

[0142] In the present invention, the position reference element is designed to be used as a guide element of a navigation system for dental surgery of known type.

[0143] A "navigation system for dental surgery" refers to a computer-assisted navigation system that makes it possible to provide visual assistance to the physician during dental surgery. Several guidance techniques exist (e.g., by optical or electromagnetic fluoroscopy), but the goal remains the same, namely to provide accurate feedback of the position of the dental stabilization block 100 using medical imaging.

[0144] In practice, when the position referencing element moves in response to at least one movement of the patient's head, the position referencing element is adapted to trigger a registration of one or more dental images associated with the patient based on the movement of the patient's head.

[0145] The present invention also includes a first tooth stabilization system.

[0146] In practice, the first dental stabilization system includes the dental stabilization block 100 according to the second embodiment of the third way of implementing the present invention and the position reference element as described above.

[0147] In particular, the position reference element is configured as at least one support element 142 , 143 coupled to a free end region of the extension branch 140 .

[0148] The present invention also includes a second tooth stabilization system.

[0149] In practice, the second dental stabilization system comprises two dental stabilization blocks 100 according to any of the variants of the present invention.

[0150] In particular, the two dental stabilization blocks 100 of the second dental stabilization system are configured to be positioned on opposite sides of the patient's mouth.

[0151] Finally, as [ Figure 10 ] As shown, the present invention includes a method 200 for tooth stabilization during dental surgery.

[0152] First, the method 200 includes the step of installing 210 at least one tooth stabilization block 100 according to any variation of the present invention on the patient's upper and lower molars and / or premolars (hereinafter referred to as "teeth") in the patient's mouth.

[0153] The method 200 then comprises the step of introducing 220 into the inlet orifice 1131 an end portion of a device for injecting a bite registration material intended to at least harden and be moulded on the teeth.

[0154] Finally, the method 200 includes the step 230 of injecting a bite registration material into the inlet aperture 1131 .

[0155] The present invention has been described and illustrated. However, the invention is not limited to the embodiments presented. Indeed, many combinations of variations, alternatives, embodiments, and implementations are conceivable without substantially modifying the invention.
