Description

Technical Field

[0001] The present invention relates to the field of oral medicine technology, and in particular to a device for uprighting a mesial impacted tooth. Furthermore, the present invention also relates to a closure device for uprighting a distal impacted tooth. Background Art

[0002] Mesial impaction occurs when a tooth's crown tilts toward the mesial direction (closer to the midline of the mouth) during eruption due to abnormal position and angle, preventing it from erupting normally. This is common in mandibular second or third molars. This type of impaction, especially completely impacted mesial impaction, often causes pain, infection, and damage to adjacent teeth. To avoid these problems, the impacted tooth should be promptly extracted or orthodontically straightened.

[0003] Currently, the main treatments for orthodontic correction of mesial impacted teeth at the distal end of the mandibular arch include surgically combined with force-attachment orthodontics and archwire orthodontics. The surgically combined force-attachment orthodontics method requires oral surgery to expose a portion of the impacted tooth's crown. A force-attachment is then bonded to the distal or buccal portion of the crown. Using implant anchorage on the mandibular ramus or other dental support in the mandibular arch, a distal force is applied to the force-attachment, thereby guiding the mesial impacted molar to distal upright position. When using force-attachment orthodontics for surgical correction of mesial impacted teeth, consideration must be given to both clinical exposure and selection of the force-application site and the appropriate force-application direction. The force-attachment used can be a buccal tube, a tooth traction chain, or other types of force-attachment. This surgical approach for mesial impacted teeth not only involves the trauma of the initial force-attachment implantation but also carries the risk of the bonded force-attachment falling out, necessitating a secondary surgery. Factors that lead to the loss of load-bearing accessories include the operation site being located at the distal end of the dental arch, limited clinical operation field of view, limited operation space, wound bleeding and exudate affecting the bonding strength, etc. Archwire upright orthodontic method is to insert one end of the archwire into the mesial of the impacted crown (suitable for horizontal impaction) or the impacted crown The facial pit and groove (suitable for mesial impaction), and the other end is fixed on the front support molar, thereby providing distal upright prying force for the impacted tooth. Archwire upright orthodontics does not require exposure of the crown of the impacted tooth. However, the existing archwire upright orthodontics also has defects: the existing fixed archwire fixing parts are mostly large in size. When fixed on the lingual side of the support tooth, the tongue feels like a foreign body. When fixed on the buccal side, it affects the alignment of the support tooth. When fixed on the maxillary surface of the support tooth, it is easily interfered with by the occlusion of the maxillary teeth. In addition, the existing archwire fixings also have the problem of high difficulty and long time in changing the archwire, which affects the patient experience and cooperation. Summary of the Invention

[0004] The main advantage of the present invention is that it provides an uprighting device for uprighting mesial impacted teeth, which can strengthen the fixation of the arch wire, prevent the arch wire from falling off and facilitate the replacement of the arch wire.

[0038] Referring to the accompanying drawings of the present invention Figures 1 to 14, the uprighting device for uprighting mesial impacted teeth according to the first embodiment of the present invention is illustrated, which includes an arch wire 10 and an arch wire fixture 20, wherein the arch wire 10 has a fixed end 11 and a force-applying end 12, and the arch wire fixture 20 has a mesial fixing portion 21 and a distal fixing portion 22, wherein the fixed end 11 of the arch wire 10 is fixed to the mesial fixing portion 21, and the force-applying end 12 passes through the distal fixing portion 22 and is exposed. Accordingly, the arch wire fixture 20 is configured to be fixed to the crown of the anchoring tooth 400 through the mesial fixing portion 21 and the distal fixing portion 22. Accordingly, as shown in the accompanying drawings Figure 7 and Figure 8 As shown, the mesial fixing portion 21 of the arch wire fixing member 20 is configured to be fixed on the mesial side of the crown of the supporting tooth 400, and the distal fixing portion 22 of the arch wire fixing member 20 is configured to be fixed on the distal side of the crown of the supporting tooth 400, so that the setting position of the arch wire 10 can be fixed by the arch wire fixing member 20 and the arch wire 10 can continue to act on the impacted tooth 600 within a preset time. Preferably, the arch wire 10 is made of superelastic nickel-titanium alloy, which has appropriate elasticity and stability. Figure 7 and Figure 8 As shown, the force-applying end 12 of the arch wire 10 of the uprighting device for uprighting a mesial impacted tooth according to the first embodiment of the present invention can be connected to the impacted tooth 600 according to the distribution of the pits and cusps of the impacted tooth 600. The force-applying end 12 of the arch wire 10 is configured to be connected to the impacted tooth 600. The grooves on the surface of the tooth are formed so that the force-applying end 12 of the arch wire 10 is deformed so as to be able to press against the impacted tooth 600. The surface and the impacted tooth 600 are pulled upright in the mesial direction away from the center.

[0039] As shown in the attached figure Figures 1 to 14 As shown, the arch wire fixture 20 of the uprighting device for uprighting a mesial impacted tooth according to the first embodiment of the present invention forms an arch wire channel 200, wherein the arch wire channel 200 has an arch wire inlet 201 and an arch wire outlet 202, wherein the arch wire inlet 201 of the arch wire channel 200 is formed at the mesial fixing portion 21 of the arch wire fixture 20, and the arch wire outlet 202 is formed at the distal fixing portion 22 of the arch wire fixture 20, wherein the arch wire channel 200 is configured such that the force applying end 12 is adapted to pass through the arch wire inlet 201 into the arch wire channel 200 and pass through the arch wire outlet 202 of the arch wire channel 200.

[0040] As shown in the attached figure Figures 1 to 14 As shown in FIG. 1 , the archwire fixing member 20 of the uprighting device for uprighting mesial impacted teeth according to the first embodiment of the present invention further comprises a buccal fixing portion 23 and a lingual fixing portion 24, wherein the buccal fixing portion 23 and the lingual fixing portion 24 are respectively arranged between the mesial fixing portion 21 and the distal fixing portion 22. Figure 7 and Figure 8 As shown, the buccal fixing portion 23 of the archwire fixture 20 is configured to be fixed on the buccal side of the crown of the anchor tooth 400, and the lingual fixing portion 24 of the archwire fixture 20 is configured to be fixed on the lingual side of the crown of the anchor tooth 400. The buccal fixing portion 23 and the lingual fixing portion 24 of the archwire fixture 20 help to fix the mesial fixing portion 21 and the distal fixing portion 22 on the mesial and distal sides of the crown of the anchor tooth 400. Preferably, the vertical height of the buccal fixing portion 23 and the lingual fixing portion 24 is not less than 2 mm to facilitate the user's fixing operation and prevent them from falling off under force. More preferably, the vertical height of the buccal fixing portion 23 and the lingual fixing portion 24 is not less than 5 mm. Preferably, the buccal fixing portion 23, the lingual fixing portion 24, the mesial fixing portion 21 and the distal fixing portion 22 are integrally formed to form a sleeve-like structure. Correspondingly, the buccal fixing portion 23 of the arch wire fixture 20 of the uprighting device for uprighting mesial impacted teeth of the present invention can provide a welding or embedding site for the buccal tube, so that the arch wire fixture 20 of the uprighting device for uprighting mesial impacted teeth of the present invention can be used as a part of orthodontic braces, which not only allows the patient to perform uprighting treatment of mesial impacted teeth and orthodontics of the entire teeth at the same time, but also can disperse the reaction force of the impacted teeth on the anchor teeth through the braces, thereby ensuring the fixation of the arch wire fixture 20 and the positioning of the arch wire 10.

[0041] As shown in the attached figure Figure 7 and Figure 8 As shown, when the force-applying end 12 of the arch wire 10 of the uprighting device for uprighting the mesial impacted tooth of the present invention is bent and abuts against the impacted tooth 600, When the tooth is in the upright position, the deformation force of the force-applying end 12 of the arch wire 10 acts on the impacted tooth to form an upright effect on the impacted tooth.

[0042] It is worth noting that the present invention solves the defects of existing arch wire orthodontics by fixing the arch wire 10 with the arch wire fixing member 20: first, the arch wire is fixed by the mesial fixing part 21 and the distal fixing part 22, which solves the problem of the existing arch wire fixing by the anchoring tooth. The disadvantage of the surface fixing arch wire is that the arch wire is easy to fall off, and since the mesial fixing part 21 and the distal fixing part 22 are respectively located at the mesial side and the distal side of the anchoring tooth, the distance between the two can be set as far as possible to avoid the fixing part being set at the anchoring tooth. When the teeth are facing up, the elasticity of the arch wire is limited (the elasticity of the arch wire is too high, which will reduce its rigidity and is not conducive to providing the force required to straighten the mesial impacted teeth). The surface fixing part needs to have a certain thickness to ensure the arch wire is fixed, which will significantly raise the bite and reduce the patient's comfort. The present invention fixes the arch wire by the mesial fixing part 21 and the distal fixing part 22, which can minimize the support teeth. The thickness of the surface ensures the comfort of the patient when biting.

[0043] As shown in the attached figure Figures 1 to 14 As shown, the mesial fixing portion 21 of the archwire fixture 20 of the uprighting device for uprighting mesial impacted teeth according to the first embodiment of the present invention forms a guide slot 203. The guide slot 203 is connected to the archwire inlet 201 of the archwire channel 200 and extends from the archwire inlet 201 to the outside of the lingual fixing portion 24, where it is exposed. Accordingly, the guide slot 203 allows a user (e.g., a dentist) to insert the force-applying end 12 of the archwire 10 through the guide slot 203 into the archwire inlet 201 of the archwire channel 200 and further pass it through the archwire outlet 202 of the archwire channel 200. Preferably, the outer opening of the guide slot 203 is wedge-shaped to facilitate removal of the archwire fixture 20 after the impacted tooth uprighting treatment is completed.

[0044] As shown in the attached figure Figures 1 to 14 As shown, preferably, the guide groove 203 is formed on the outer surface of the mesial fixing portion 21, and the guide groove 203 and the arch wire channel 200 form a 7-shape. In other words, the guide groove 203 of the mesial fixing portion 21 of the arch wire fixing member 20 of the uprighting device for uprighting mesial impacted teeth of the present invention not only facilitates the user to insert the arch wire 10 into the arch wire channel 200, but also facilitates the fixation of the fixed end 11 of the arch wire 10. For example, the fixed end 11 and the force-applying end 12 of the arch wire 10 can be set to form an appropriate angle (preferably perpendicular to each other). Accordingly, when the force-applying end 12 of the arch wire 10 passes through the arch wire outlet 202 of the arch wire channel 200 and is abutted against the impacted tooth 600, When the arch wire 10 is inserted into the arch wire channel 200, the fixed end 11 of the arch wire 10 will press against the mesial fixed portion 21, so that the arch wire 10 is kept in a proper position. In addition, after the arch wire 10 is inserted into the arch wire channel 200, the fixation of the arch wire 10 can be strengthened by coating the guide groove 203 with adhesive material or filling resin, and the fixed end 11 of the arch wire 10 can be hidden to prevent the fixed end 11 from being bitten or touched, causing the arch wire 10 to loosen. In this way, the uprighting device for uprighting mesial impacted teeth of the present invention is used in the support teeth. The surface does not require additional or special arch wire fixing parts or elements, and does not increase the occlusal height, and can ensure that the fixed end 11 of the arch wire 10 is fixed, thereby simplifying the entire impacted tooth uprighting surgery and improving the patient's surgical experience.

[0045] As shown in the attached figure Figures 1 to 14 As shown, the archwire fixture 20 of the uprighting device for uprighting mesial impacted teeth according to the first embodiment of the present invention further includes a groove adaptor 25, wherein the groove adaptor 25 is surrounded by the mesial fixing portion 21, the distal fixing portion 22, the buccal fixing portion 23, and the lingual fixing portion 24, and the mesial fixing portion 21, the distal fixing portion 22, the buccal fixing portion 23, the lingual fixing portion 24, and the groove adaptor 25 are integrally formed. Preferably, the groove adaptor 25 has a forming side 251 and a fixing side 252 opposite the forming side 251, wherein the forming side 251 is recessed downward to form a groove 2510, and the fixing side 252 is convex outward to at least partially adapt to the groove of the crown of the anchor tooth 400. It can be understood that, according to the patient model, the outer shape of the groove adaptor 25 matches the groove morphology of the patient's occlusal surface. Accordingly, the forming side 251 of the groove adapter 25 should avoid the occlusal position of the support tooth 400 and the corresponding maxillary tooth as much as possible to avoid increasing the occlusal height of the support tooth 400. It is worth noting that the forming side 251 of the groove adapter 25 is concave downward, which can improve the occlusion and increase the patient's comfort during the distal upright treatment of the impacted tooth. In addition, since the fixed side 252 is convex outward, when the fixed side 252 of the groove adapter 25 is coated with adhesive, it can be at least partially adhered to the crown of the support tooth 400. The protruding part of the surface (such as the position of the tooth cusp) is increased to increase the contact surface between the arch wire fixture 20 and the crown of the anchor tooth 400 and ensure that the arch wire fixture 20 is fixed to the anchor tooth 400.

[0046] As shown in the attached figure Figure 6 and Figure 12As shown, the arch wire channel 200 of the arch wire fixture 20 of the uprighting device for uprighting mesial impacted teeth according to the first embodiment of the present invention is partially exposed at the bottom 2511 of the groove 2510 of the forming side 251 of the pit and fissure adapter 25, so that the arch wire 10 is partially exposed. Accordingly, the arch wire 10 is partially exposed in the groove 2510, which can ensure that the user can avoid the arch wire 10 installed in the arch wire channel 200 from being bitten, while facilitating the user to observe the arch wire 10 during the process of replacing the arch wire 10. In addition, the arch wire 10 is partially exposed in the groove 2510, which also allows the user (or dentist) to place or set adhesive material on the arch wire 10 through the groove 2510 to further fix the arch wire 10. As shown in the accompanying drawings Figure 6 and Figure 12 As shown, accordingly, only a portion of the portion between the fixed end 11 and the force-applying end 12 of the arch wire 10 is exposed through the groove 2510, and the remaining portion is hidden in the arch wire channel 200, which can prevent the arch wire 10 from facing the support tooth. The facial part is loose or falling off due to biting.

[0047] As shown in the attached figure Figures 1 to 14 As shown, the archwire channel 200 of the archwire fixture 20 of the uprighting device for uprighting a mesial impacted tooth according to the first embodiment of the present invention is used to partially expose the archwire 10 and is set at the bottom 2511 of the groove 2510 of the groove adapter 25 to prevent the anchor tooth 400 from biting the archwire 10 when occluding with the maxillary teeth, causing the archwire 10 to fall off or deform, thereby affecting the uprighting effect of the archwire 10 on the impacted tooth 600. In addition, the forming side 251 of the groove adapter 25 is concave downward and the fixing side 252 is convex outward, which also adapts to the crown shape of the anchor tooth 400 and ensures that the archwire fixture 20 is fixed to the crown of the anchor tooth 400 to the greatest extent without affecting the occlusion of the maxillary teeth.

[0048] As shown in the attached figure Figure 6 、 Figure 13 and Figure 14 As shown, the uprighting device for uprighting a mesial impacted tooth according to the first embodiment of the present invention further comprises a push spring 30, wherein the push spring 30 is adapted to be threaded through the force-applying end 12 of the arch wire 10, and the natural length of the push spring 30 (the length naturally extended when not subjected to external force) is greater than the length of the force-applying end 12 of the arch wire 10, so that the supporting end 32 of the push spring 30 is supported on the impacted tooth 600. When the surface is pressed, the deformation force of the push spring 30 can act on the impacted tooth 600. The surface is used to form traction on the impacted tooth 600 and make the impacted tooth 600 stand upright in the direction away from the mesial.

[0049] It is worth noting that the natural length of the push spring 30 of the uprighting device for uprighting the mesial impacted tooth of the present invention is greater than the length of the force-applying end 12 of the arch wire 10. Therefore, when the support end 32 of the push spring 30 is supported on the impacted tooth 600, the push spring 30 is in a state of being pushed forward. When the surface is pressed, the push spring 30 is compressed, and the push spring 30 is inserted into the force-applying end 12 of the arch wire 10, which helps to keep the push spring 30 in a proper position.

[0050] As shown in the attached figure Figure 6 、 Figure 13 and Figure 14 As shown, the push spring 30 of the uprighting device for uprighting a mesial impacted tooth according to the first embodiment of the present invention has a supporting end 31 and a threaded end 32. The distal fixing portion 22 of the archwire fixture 20 forms a threaded hole 221, wherein the threaded hole 221 is disposed around the archwire outlet 202 of the archwire channel 200 so that the thread of the threaded end 32 of the push spring 30 can be fixed within the threaded hole 221 without affecting the threading of the push spring 30 through the force-applying end 12 of the archwire 10. Preferably, the shape and size of the threaded hole 221 are adapted to the thread of the threaded end 32 of the push spring 30 so that the thread of the threaded end 32 of the push spring 30 can be threaded within the threaded hole 221. It is worth noting that the thread of the screw connection end 32 of the push spring 30 is screwed with the screw connection hole 221, which makes it convenient for the user to make the push spring 30 abut against the impacted tooth 600. When the push spring 30 is rotated and compressed, the screw-connected end 32 of the push spring 30 is rotated and positioned, and on the other hand, the position of the screw-connected end 32 of the push spring 30 is fixed more reliably. It can be understood that the push spring 30 of the uprighting device for uprighting mesial impacted teeth of the present invention is generally only used for distal uprighting of impacted teeth after eruption.

[0051] As shown in the attached figure Figure 3 and Figure 5 As shown, the mesial fixing portion 21 of the arch wire fixing member 20 of the uprighting device for uprighting mesial impacted teeth according to the first embodiment of the present invention forms a mesial fixing groove 210, and the distal fixing portion 22 forms a distal fixing groove 220, so that the bonding material can be coated on the groove wall of the mesial fixing groove 210 and the groove wall of the distal fixing groove 220, and the mesial fixing portion 21 and the distal fixing portion 22 are fixed to the mesial side and distal side of the crown of the support tooth 400 by glue.

[0052] As shown in the attached figure Figure 3 and Figure 5 As shown, the buccal fixing portion 23 of the arch wire fixing member 20 of the uprighting device for uprighting mesial impacted teeth according to the first embodiment of the present invention forms a buccal fixing groove 230, and the lingual fixing portion 24 forms a lingual fixing groove 240, so that the bonding material (adhesive or glue) can be coated on the groove wall of the buccal fixing groove 230 and the groove wall of the lingual fixing groove 240, and the buccal fixing portion 23 and the lingual fixing portion 24 are fixed to the buccal side and the lingual side of the anchor tooth 400 by adhesive.

[0053] Preferably, the mesial fixing portion 21, the distal fixing portion 22, the buccal fixing portion 23 and the lingual fixing portion 24 are integrally formed, and the mesial fixing groove 210, the distal fixing groove 220, the buccal fixing groove 230 and the lingual fixing groove 240 are connected end to end, so that the mesial fixing groove 210, the distal fixing groove 220, the buccal fixing groove 230 and the lingual fixing groove 240 form a through groove. The mesial fixing portion 21, the distal fixing portion 22, the buccal fixing portion 23 and the lingual fixing portion 24 of the arch wire fixing part 20 of the uprighting device for uprighting mesial impacted teeth of the present invention are integrally formed, so that the arch wire fixing part 20 forms a whole and can be fixed to the crown of the supporting tooth 400 at one time. Teeth of different people Surface, especially molars The surface shapes of the surfaces are generally different. The mesial fixing groove 210, the distal fixing groove 220, the buccal fixing groove 230 and the lingual fixing groove 240 form a through groove, which helps to better adapt to the anchor tooth 400. In addition, when the adhesive is applied to the groove walls of the mesial fixing groove 210, the distal fixing groove 220, the buccal fixing groove 230, and the lingual fixing groove 240, the adhesive or glue may be unevenly applied. The formation of a through groove by the mesial fixing groove 210, the distal fixing groove 220, the buccal fixing groove 230, and the lingual fixing groove 240 also helps the adhesive to flow and be evenly distributed along the groove walls under extrusion during the fixation process, so as to better fix the arch wire fixture 20 to the crown of the anchor tooth 400.

[0054] Attached Figure 15 and Figure 16The figure shows an optional implementation of the uprighting device for uprighting mesial impacted teeth according to the first embodiment of the present invention, which includes an arch wire 10 and an arch wire fixture 20A, wherein the arch wire 10 has a fixing end 11 and a force-applying end 12, and the arch wire fixture 20A has a mesial fixing portion 21A, a distal fixing portion 22A, a buccal fixing portion 23A and a lingual fixing portion 24A, wherein the buccal fixing portion 23A and the lingual fixing portion 24A are respectively arranged between the mesial fixing portion 21A and the distal fixing portion 22A, wherein the The mesial fixing portion 21A, the distal fixing portion 22A, the buccal fixing portion 23A, and the lingual fixing portion 24A of the arch wire holder 20A surround a cavity 200A. The mesial fixing portion 21A forms an arch wire entrance 201A, and the distal fixing portion 22A forms an arch wire exit 202A. Both the arch wire entrance 201A and the arch wire exit 202A communicate with the cavity 200A, thereby forming an arch wire passage 204A with the arch wire entrance 201A, the arch wire exit 202A, and the cavity 200A. Furthermore, because the mesial fixing portion 21A, the distal fixing portion 22A, the buccal fixing portion 23A, and the lingual fixing portion 24A of the arch wire holder 20A are disposed around the cavity 200A, the arch wire holder 20A has a sleeve-like structure. It is worth noting that the cavity 200A formed by the archwire anchor 20A can prevent the archwire anchor 20A from interfering with occlusion.
