Description

Technical Field

[0001] This utility model relates to the field of oral medicine technology, and in particular to an erecting device for uprighting mesial impacted teeth. Furthermore, this utility model also relates to an occlusal pad device for uprighting distal impacted teeth. Background Technology

[0002] Mesial impaction of teeth refers to the phenomenon where teeth fail to erupt normally due to abnormal position or angle, causing the crown to tilt mesially (closer to the midline of the mouth). This is commonly seen in the mandibular second or third molars. Such impacted teeth, especially completely impacted mesial impacted teeth, often cause problems such as pain, infection, and damage to adjacent teeth. To avoid these problems, timely extraction or orthodontic treatment is necessary to correct the impacted tooth.

[0003] Currently, the main orthodontic treatments for mesial impacted teeth at the distal end of the mandibular dental arch include surgical upright orthodontics with force attachments and archwire upright orthodontics. Surgical upright orthodontics with force attachments requires initial oral surgery to expose part of the crown of the impacted tooth. Then, force attachments are bonded to the distal portion of the crown or buccal surface of the impacted tooth. Using implant anchorage at the mandibular ramus or the mandibular arch anchorage, a distal force is applied to the force attachments, thereby guiding the mesial impacted molar to distal upright position. When using upright orthodontics with force attachments for mesial impacted teeth, both the clinical exposure and selection of the force application site and the appropriate direction of force application must be considered. The force attachments used can be buccal tubes, impacted tooth traction chains, or other types of force attachments. This surgical approach for mesial impacted teeth carries the risk of trauma during the initial implantation of the force attachments, as well as the risk of attachment detachment, necessitating a second surgery. Factors leading to the detachment of force-bearing attachments include the operation site being located distal to the dental arch, limited clinical field of vision, limited operating space, and wound bleeding and exudation affecting bonding strength. The archwire upright orthodontic method involves inserting one end of the archwire into the mesial part of the impacted tooth crown (suitable for horizontally impacted teeth) or the fissure on the ulnar surface of the impacted tooth crown (suitable for mesial impacted teeth), while the other end is fixed to the anterior anchorage molar, thus providing distal upright levering force for the impacted tooth. The archwire upright orthodontic method does not require exposure of the impacted tooth crown. However, existing archwire upright orthodontic methods also have drawbacks: most existing archwire fixation devices are relatively large; when fixed on the lingual side of the anchorage tooth, they cause a noticeable foreign body sensation in the tongue; when fixed on the buccal side, they affect the alignment of the anchorage tooth; and when fixed on the occlusal surface of the anchorage tooth, they are easily interfered with by maxillary occlusion. Furthermore, existing archwire fixation devices also present challenges in terms of the difficulty and time required for archwire replacement, affecting patient experience and cooperation.

[0035] Refer to the accompanying drawings in this utility model specification. Figures 1 to 14An erection device for erecting a mesial impacted tooth according to a first embodiment of the present invention is illustrated. It includes an archwire 10 and an archwire fixation member 20. The archwire 10 has a fixed end 11 and a force-applying end 12. The archwire fixation member 20 has a mesial fixation portion 21 and a distal fixation portion 22. The fixed end 11 of the archwire 10 is fixed to the mesial fixation portion 21, and the force-applying end 12 protrudes from the distal fixation portion 22 and is exposed. Accordingly, the archwire fixation member 20 is configured to be fixed to the crown of the anchorage tooth 400 through the mesial fixation portion 21 and the distal fixation portion 22. Accordingly, as shown in the accompanying drawings... Figure 7 and Figure 8 As shown, the mesial fixation portion 21 of the archwire fixation member 20 is configured to be fixed on the mesial side of the crown of the anchorage tooth 400, and the distal fixation portion 22 of the archwire fixation member 20 is configured to be fixed on the distal side of the crown of the anchorage tooth 400. This allows the archwire 10 to be fixed in position by the archwire fixation member 20 and enables the archwire 10 to continuously act on the ulnar surface of the impacted tooth 600 for a preset time. Preferably, the archwire 10 is made of a superelastic nickel-titanium alloy, possessing appropriate elasticity and stability. (See attached figures.) Figure 7 and Figure 8 As shown, in the first embodiment of this utility model, the force-applying end 12 of the archwire 10 for the erection device for erecting mesial impacted teeth can be connected to the ulnar surface of the impacted tooth 600 according to the distribution of the pits and cusps of the impacted tooth 600, so as to apply force to the impacted tooth 600 and to erect the impacted tooth 600 away from the mesial direction. It can be understood that the force-applying end 12 of the archwire 10 is configured to connect to the pits and cusps of the ulnar surface of the impacted tooth 600, so that the force-applying end 12 of the archwire 10 deforms, so as to press against the ulnar surface of the impacted tooth 600 and pull the impacted tooth 600 away from the mesial direction to erect it.

[0036] As shown in the attached image. Figures 1 to 14 As shown, according to the first embodiment of the present invention, the archwire fixation member 20 for an erection device for mesial impacted teeth forms an archwire channel 200, wherein the archwire channel 200 has an archwire inlet 201 and an archwire outlet 202, wherein the archwire inlet 201 of the archwire channel 200 is formed in the mesial fixation portion 21 of the archwire fixation member 20, and the archwire outlet 202 is formed in the distal fixation portion 22 of the archwire fixation member 20, wherein the archwire channel 200 is configured such that the force-applying end 12 is adapted to enter the archwire channel 200 from the archwire inlet 201 and exit from the archwire outlet 202 of the archwire channel 200.

[0037] As shown in the attached image. Figures 1 to 14As shown, the archwire fixation member 20 of the erection device for erecting mesial impacted teeth according to the first embodiment of this utility model further includes a buccal fixation part 23 and a lingual fixation part 24, wherein the buccal fixation part 23 and the lingual fixation part 24 are respectively disposed between the mesial fixation part 21 and the distal fixation part 22. Accordingly, as shown in the figure... Figure 7 and Figure 8 As shown, the buccal fixation portion 23 of the archwire fixation member 20 is configured to be fixed to the buccal side of the crown of the anchorage tooth 400, and the lingual fixation portion 24 of the archwire fixation member 20 is configured to be fixed to the lingual side of the crown of the anchorage tooth 400. The buccal fixation portion 23 and the lingual fixation portion 24 of the archwire fixation member 20 help to fix the mesial fixation portion 21 and the distal fixation portion 22 to the mesial and distal sides of the crown of the anchorage tooth 400. Preferably, the vertical height of the buccal fixation portion 23 and the lingual fixation portion 24 is not less than 2 mm to facilitate the user's fixation operation and prevent them from falling off under force. More preferably, the vertical height of the buccal fixation portion 23 and the lingual fixation portion 24 is not less than 5 mm. Preferably, the buccal fixation portion 23, the lingual fixation portion 24, the mesial fixation portion 21, and the distal fixation portion 22 are integrally formed to form a sleeve-like structure. Accordingly, the buccal fixing part 23 of the archwire fixation member 20 of the upright device for upright mesial impacted teeth of this utility model can provide a welding or embedding site for the buccal tube, so that the archwire fixation member 20 of the upright device for upright mesial impacted teeth of this utility model can be used as part of the orthodontic braces. This not only allows the patient to undergo upright treatment of mesial impacted teeth and overall orthodontics at the same time, but also disperses the reaction force of the impacted teeth on the anchor teeth through the braces, ensuring the fixation of the archwire fixation member 20 and the positioning of the archwire 10.

[0038] As shown in the attached image. Figure 7 and Figure 8 As shown, when the force-applying end 12 of the archwire 10 of the present invention for the erection device for erecting mesial impacted teeth is bent and abutted against the ulnar surface of the impacted tooth 600, the deformation force of the force-applying end 12 of the archwire 10 acts on the impacted tooth to form an erection effect on the impacted tooth.

[0039] It is worth noting that this invention addresses the shortcomings of existing archwire orthodontics by fixing the archwire 10 to the archwire fixation member 20. Firstly, by fixing the archwire through the mesial fixation part 21 and the distal fixation part 22, the drawback of archwires easily falling out when fixed to the uvial surface of the anchorage tooth is solved. Furthermore, since the mesial fixation part 21 and the distal fixation part 22 are located on the mesial and distal sides of the anchorage tooth, respectively, the distance between them can be set as far as possible, avoiding the limitation on archwire elasticity when the fixation member is placed on the uvial surface of the anchorage tooth (excessive archwire elasticity leads to reduced rigidity, which is not conducive to providing the force required to upright mesial impacted teeth). Secondly, existing fixation members placed on the uvial surface of the anchorage tooth require a certain thickness to ensure archwire fixation, which significantly raises the occlusion and reduces patient comfort. This invention, by fixing the archwire through the mesial fixation part 21 and the distal fixation part 22, can minimize the thickness of the uvial surface of the anchorage tooth, ensuring patient comfort during occlusion.

[0040] As shown in the attached image. Figures 1 to 14 As shown, in the first embodiment of the present invention, the mesial fixation portion 21 of the archwire fixation member 20 for erecting mesial impacted teeth forms a guide groove 203, wherein the guide groove 203 communicates with the archwire inlet 201 of the archwire channel 200, and the guide groove 203 extends from the archwire inlet 201 to the outer side adjacent to the lingual fixation portion 24 and is exposed. Accordingly, the guide groove 203 allows a user (e.g., a dentist) to insert the force-applying end 12 of the archwire 10 into the archwire inlet 201 of the archwire channel 200 and further through it to exit from the archwire outlet 202 of the archwire channel 200. Preferably, the outer opening of the guide groove 203 is wedge-shaped to facilitate the removal of the archwire fixation member 20 after the erection treatment of the impacted tooth is completed.

[0041] As shown in the attached image. Figures 1 to 14As shown, preferably, the guide groove 203 is formed on the outer surface of the mesial fixation part 21, and the guide groove 203 and the archwire channel 200 form a figure-7 shape. In other words, the guide groove 203 of the mesial fixation part 21 of the archwire fixation member 20 of the present invention for the erection device for erecting mesial impacted teeth not only facilitates the user to insert the archwire 10 into the archwire channel 200, but also facilitates the fixation of the fixed end 11 of the archwire 10. For example, the fixed end 11 and the force-applying end 12 of the archwire 10 can be set at an appropriate angle (preferably perpendicular). Accordingly, when the force-applying end 12 of the archwire 10 passes through the archwire outlet 202 of the archwire channel 200 and is abutted against the ulnar surface of the impacted tooth 600, the fixed end 11 of the archwire 10 will press against the mesial fixation part 21, thereby keeping the archwire 10 in the proper position. Furthermore, after the archwire 10 is inserted into the archwire channel 200, the fixation of the archwire 10 can be strengthened by applying adhesive material or filling resin to the guide groove 203, and the fixed end 11 of the archwire 10 can be hidden to prevent the fixed end 11 from being bitten or touched, which could cause the archwire 10 to loosen. Thus, the uprighting device of this invention for uprighting mesial impacted teeth does not require additional or specialized archwire fixation components or elements on the anchoring tooth surface, and does not increase the occlusal height, ensuring that the fixed end 11 of the archwire 10 is fixed, thereby simplifying the entire surgical procedure for uprighting impacted teeth and improving the patient's surgical experience.

[0042] As shown in the attached image. Figures 1 to 14As shown, the archwire fixation member 20 of the erection device for erecting mesial impacted teeth according to the first embodiment of the present invention further includes a pit and fissure fitting portion 25, wherein the pit and fissure fitting portion 25 is surrounded by the mesial fixation portion 21, the distal fixation portion 22, the buccal fixation portion 23, and the lingual fixation portion 24, and the mesial fixation portion 21, the distal fixation portion 22, the buccal fixation portion 23, the lingual fixation portion 24, and the pit and fissure fitting portion 25 are integrally formed. Preferably, the pit and fissure fitting portion 25 has a forming side 251 and a fixing side 252 opposite to the forming side 251, wherein the forming side 251 is recessed downward to form a groove 2510, and the fixing side 252 is protruding outward to at least partially fit the pit and fissure of the crown of the anchorage tooth 400. It can be understood that, according to the patient model, the shape of the pit and fissure fitting portion 25 matches the pit and fissure morphology of the patient's occlusal surface. Accordingly, the forming side 251 of the fissure fitting 25 should avoid the occlusal position of the anchorage tooth 400 and the corresponding maxillary tooth as much as possible to avoid increasing the occlusal height of the anchorage tooth 400. It is worth noting that the forming side 251 of the fissure fitting 25 is concave downward, which can improve occlusion and increase patient comfort during distal upright treatment of impacted teeth. In addition, since the fixing side 252 protrudes outward, when the fixing side 252 of the fissure fitting 25 is coated with adhesive, it can be at least partially adhered to the protruding part of the crown of the anchorage tooth 400 (e.g., the location of the cusp), thereby increasing the contact surface between the archwire fixation member 20 and the crown of the anchorage tooth 400 and ensuring that the archwire fixation member 20 is fixed to the anchorage tooth 400.

[0043] As shown in the attached image. Figure 6 and Figure 12 As shown, in the first embodiment of the present invention, the archwire channel 200 of the archwire fixation member 20 for an erection device for mesial impacted teeth is partially exposed at the bottom 2511 of the groove 2510 on the forming side 251 of the fissure adapter 25, so that the archwire 10 is partially exposed. Accordingly, the partial exposure of the archwire 10 within the groove 2510 allows the user to observe the archwire 10 during replacement while ensuring that the archwire 10 installed in the archwire channel 200 is not bitten. Furthermore, the partial exposure of the archwire 10 within the groove 2510 also allows the user (or dentist) to place or apply bonding material through the groove 2510 to further secure the archwire 10. (See attached figures.) Figure 6 and Figure 12As shown, the portion between the fixed end 11 and the force-applying end 12 of the archwire 10 is only partially exposed through the groove 2510, while the remaining portion is hidden within the archwire channel 200. This prevents the portion of the archwire 10 directly opposite the anchoring tooth surface from being loosened or dislodged by biting.

[0044] As shown in the attached image. Figures 1 to 14 As shown, in the first embodiment of this utility model, the portion of the archwire channel 200 of the archwire fixation member 20 used to partially expose the archwire 10 is located at the bottom 2511 of the groove 2510 of the fissure fitting portion 25. This is to prevent the anchorage tooth 400 from biting the archwire 10 when it occludes with the maxillary tooth, thus preventing the archwire 10 from falling off or deforming and affecting its uprighting effect on the impacted tooth 600. Furthermore, the downward-concave forming side 251 and outward-convex fixing side 252 of the fissure fitting portion 25 also maximize the adaptation to the crown shape of the anchorage tooth 400 and ensure the archwire fixation member 20 is fixed to the crown of the anchorage tooth 400 without affecting the occlusion of the maxillary tooth.

[0045] As shown in the attached image. Figure 6 , Figure 13 and Figure 14 As shown, the erection device for erecting mesial impacted teeth according to the first embodiment of the present invention further includes a push spring 30, wherein the push spring 30 is adapted to be inserted through the force-applying end 12 of the archwire 10, and the natural length of the push spring 30 (the length naturally extended when not under external force) is greater than the length of the force-applying end 12 of the archwire 10, so that when the support end 32 of the push spring 30 is supported on the ulnar surface of the impacted tooth 600, the deformation force of the push spring 30 can act on the ulnar surface of the impacted tooth 600 to form traction on the impacted tooth 600 and to erect the impacted tooth 600 in a direction away from the mesial.

[0046] It is worth noting that the natural length of the push spring 30 in the erection device for erecting mesial impacted teeth of this utility model is greater than the length of the force-applying end 12 of the archwire 10. Therefore, when the support end 32 of the push spring 30 is supported on the ulnar surface of the impacted tooth 600, the push spring 30 is compressed. The push spring 30 passes through the force-applying end 12 of the archwire 10, which helps to keep the push spring 30 in the proper position.

[0047] As shown in the attached image. Figure 6 , Figure 13 and Figure 14As shown, the push spring 30 of the erection device for erecting mesial impacted teeth according to the first embodiment of the present invention has a support end 31 and a threaded end 32. The distal fixing portion 22 of the archwire fixing member 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 helix of the threaded end 32 of the push spring 30 can be fixed in the threaded hole 221 without affecting the push spring 30 passing through the force-applying end 12 of the archwire 10. Preferably, the shape and size of the threaded hole 221 are adapted to the helix of the threaded end 32 of the push spring 30, so that the helix of the threaded end 32 of the push spring 30 can be threaded into the threaded hole 221. It is worth noting that the helix of the threaded end 32 of the push spring 30 is threaded into the threaded hole 221. This facilitates the user's rotation and compression of the push spring 30 and rotational positioning of the threaded end 32 of the push spring 30 when the push spring 30 is pressed against the ulnar surface of the impacted tooth 600. Furthermore, it makes the position of the threaded end 32 of the push spring 30 more reliably fixed. It can be understood that the push spring 30 of this utility model's uprighting device for mesial impacted teeth is generally only used for distal uprighting traction of the impacted tooth after eruption.

[0048] As shown in the attached image. Figure 3 and Figure 5 As shown, in the first embodiment of the present invention, the archwire fixation member 20 of the erection device for erecting mesial impacted teeth has a mesial fixation groove 21 formed by the mesial fixation part 210 and a distal fixation groove 22 formed by the distal fixation part 220, so that adhesive material can be applied to the groove walls of the mesial fixation groove 210 and the distal fixation groove 220, and the mesial fixation part 21 and the distal fixation part 22 are fixed to the mesial and distal sides of the crown of the anchorage tooth 400 by adhesive.

[0049] As shown in the attached image. Figure 3 and Figure 5 As shown, in the first embodiment of the present invention, the buccal fixing part 23 of the archwire fixing member 20 for the erection device for erecting mesial impacted teeth forms a buccal fixing groove 230, and the lingual fixing part 24 forms a lingual fixing groove 240, so that an adhesive material (adhesive or glue) can be applied to the groove wall of the buccal fixing groove 230 and the groove wall of the lingual fixing groove 240, and the buccal fixing part 23 and the lingual fixing part 24 are fixed to the buccal and lingual sides of the anchorage tooth 400 by adhesive.

[0050] Preferably, the mesial fixation part 21, the distal fixation part 22, the buccal fixation part 23, and the lingual fixation part 24 are integrally formed, and the mesial fixation groove 210, the distal fixation groove 220, the buccal fixation groove 230, and the lingual fixation groove 240 are connected end to end, thereby forming a through groove. In this utility model, the archwire fixation part 20 for an erecting device for impacted mesial teeth has its mesial fixation part 21, distal fixation part 22, buccal fixation part 23, and lingual fixation part 24 integrally formed, thus making the archwire fixation part 20 a single unit and allowing it to be fixed to the crown of the anchorage tooth 400 in one go. The surface shape of the valvular surfaces of teeth, especially molars, generally varies among different individuals. The mesial fixation groove 210, distal fixation groove 220, buccal fixation groove 230, and lingual fixation groove 240 forming a continuous groove helps to better fit the valvular surface of the anchorage tooth 400. Furthermore, when adhesive is applied to the groove walls of the mesial fixation groove 210, distal fixation groove 220, buccal fixation groove 230, and lingual fixation groove 240, uneven application of the adhesive or glue is possible. The continuous groove formed by the mesial fixation groove 210, distal fixation groove 220, buccal fixation groove 230, and lingual fixation groove 240 also helps the adhesive to flow and distribute evenly along the groove walls under pressure during fixation, thus better securing the archwire fixation member 20 to the crown of the anchorage tooth 400.

[0051] Attached image Figure 15 and Figure 16The image shown is an optional embodiment of an erection device for mesial impacted teeth according to the first embodiment of the present invention. It includes an archwire 10 and an archwire fixation member 20A. The archwire 10 has a fixing end 11 and a force-applying end 12. The archwire fixation member 20A has a mesial fixation part 21A, a distal fixation part 22A, a buccal fixation part 23A, and a lingual fixation part 24A. The buccal fixation part 23A and the lingual fixation part 24A are respectively disposed between the mesial fixation part 21A and the distal fixation part 22A. The mesial fixation portion 21A, distal fixation portion 22A, buccal fixation portion 23A, and lingual fixation portion 24A of the archwire fixation member 20A form a cavity 200A. The mesial fixation portion 21A forms an archwire inlet 201A, and the distal fixation portion 22A forms an archwire outlet 202A. Both the archwire inlet 201A and the archwire outlet 202A are connected to the cavity 200A, thereby forming an archwire channel 204A. Furthermore, since the mesial fixation portion 21A, distal fixation portion 22A, buccal fixation portion 23A, and lingual fixation portion 24A of the archwire fixation member 20A are arranged around the cavity 200A, the archwire fixation member 20A has a sleeve-like structure. It is worth noting that the cavity 200A formed by the archwire fixation member 20A can prevent the archwire fixation member 20A from interfering with occlusion. Preferably, the vertical height of the buccal fixation part 23A and the lingual fixation part 24A is not less than 2mm to facilitate the user's fixation operation and prevent them from falling off under force. More preferably, the vertical height of the buccal fixation part 23A and the lingual fixation part 24A is not less than 5mm.

[0052] As shown in the attached image. Figure 15 and Figure 16 As shown, in the first embodiment of the present invention, the fixed end 11 of the archwire 10 for the erection device for erecting mesial impacted teeth is fixed to the mesial fixing part 21A of the archwire fixing member 20A, and the force-applying end 12 passes through the distal fixing part 22A and is exposed.

[0053] As shown in the attached image.
