Description

Technical Field

[0001] The present invention relates to the technical field of medical supplies, and in particular to a dental orthodontic appliance. Background Art

[0002] In addition to affecting chewing function or overall appearance, crooked teeth can also cause oral health problems such as tooth decay, periodontal disease or abnormal tooth wear. Severe cases can lead to deformation of the alveolar bone, jaw or face. For this reason, more and more people are undergoing orthodontic treatment for the beauty and health of their teeth.

[0003] There are many situations that lead to uneven teeth. The first situation is that the teeth that have grown and are neat are missing, and no remedial measures such as dentures are taken in time, which makes other teeth loose, and eventually leads to uneven teeth. This is because the teeth on both sides of the missing teeth are subjected to the bite force during the occlusion process, causing the teeth on both sides to tilt toward the gap formed by the missing teeth, and the teeth on both sides will also stretch, resulting in malocclusion. Further development will affect the chewing function, and even prevent the use of remedial measures such as dentures for the missing parts in the future.

[0004] The second situation is: the user's congenital deciduous teeth are generally neat, but during the period of tooth replacement, the loss of deciduous teeth causes other deciduous teeth to become loose, making the width of the tooth gap between the deciduous teeth smaller than the width of the permanent teeth to grow. At this time, the permanent teeth are squeezed by the deciduous teeth, so the permanent teeth grow crooked, which leads to uneven teeth. If the situation is serious, it will also affect the normal development of the user's alveolar bone and jawbone.

[0005] The third situation is: the user's congenital misaligned deciduous teeth cause the permanent teeth that grow out during the tooth replacement period to be squeezed by the deciduous teeth, the alveolar bone or the jawbone, etc., causing the permanent teeth to grow crookedly and resulting in misaligned teeth.

[0006] For the first problem mentioned above, the common solution at present is to have users with missing teeth get dentures or dental implants as soon as possible. However, if the users with missing teeth cannot get dentures or dental implants in time due to other reasons, the teeth may become uneven. The existing technical means can only correct the teeth when they are uneven, and cannot prevent the situation where the teeth that have grown and are neatly arranged become uneven due to missing teeth.

[0007] In response to the second and third problems mentioned above, the existing technical means usually wait until the teeth grow out before correcting the teeth, and the common way to correct teeth is to adhere the braces to the surface of each tooth, and then install the correction wire on each brace. Further, pull the correction wire to change the arrangement of the teeth, thereby changing the overall appearance of the teeth and changing the malocclusion. However, the above-mentioned technical means of teeth correction require users to wear them for a long time, and it is easy for food residues to remain around the braces, which leads to problems such as long correction period, unsightly and unhygienic. Moreover, the above-mentioned existing teeth correction technology cannot prevent users and adults from having uneven teeth. Therefore, the existing teeth correction technology cannot fundamentally solve the problems of crooked teeth and uneven teeth. Summary of the invention

[0008] The present invention provides a dental orthodontic appliance to solve the problem that the existing dental orthodontic appliances cannot fundamentally solve the problem of crooked teeth and uneven teeth arrangement.

[0009] The present application provides a dental brace, a correction brace and one or more tooth gap space occupying blocks arranged on the correction brace;

[0010] The corrective braces are arranged according to the shape of the teeth to be corrected and can play a corrective role on the teeth to be corrected; the tooth gap placeholders are arranged correspondingly and matchingly according to the position, shape and size of the tooth gaps of the teeth to be corrected, so that when the dental braces are worn, the tooth gap placeholders enter and occupy the corresponding tooth gaps.

[0011] Optionally, the tooth gap includes a gap formed by missing teeth.

[0012] Optionally, the material of the tooth gap placeholder includes resin material.

[0013] Optionally, the material of the orthodontic braces includes resin material.

[0014] Optionally, the material of the orthodontic braces includes elastic polymer material.

[0015] Optionally, the orthodontic braces are used for orthodontic treatment of users in the period of replacement teeth, and the tooth gap spacer is set at the position of the erupting tooth, and its size is set so as not to contact the gingival end surface of the erupting tooth. Optionally, the tooth gap spacer can be adaptively cut as the erupting tooth grows to avoid contact with the erupting tooth. Optionally,

[0016] The tooth gap space-occupying block has a layered structure, and the layers toward the erupting teeth are removed according to the growth height of the erupting teeth. The number of removed layers can prevent the space-occupying block from interfering with the erupting teeth.

[0017] Optionally, the connection method of the tooth gap placeholders with a hierarchical structure includes: the hierarchical structures are connected by nesting layer by layer.

[0018] Optionally, the connection method of the tooth gap space occupying block with a layered structure includes: the layered structures are connected layer by layer by screw connection.

[0019] Compared with the prior art, the present invention has the following advantages: the dental brace of the present invention comprises: a correction brace and one or more tooth gap placeholders arranged on the correction brace; the correction brace is arranged according to the shape of the teeth to be corrected and can correct the teeth to be corrected; the tooth gap placeholders are arranged correspondingly and matchingly according to the position, shape and size of the tooth gap of the teeth to be corrected, so that when the dental brace is worn, the tooth gap placeholders enter and occupy the corresponding tooth gap. When using the dental brace provided by the present invention, by setting the tooth gap placeholders at the corresponding tooth gap position during correction, the adverse effects of the tooth gap on the correction can be avoided, and the correction effect can be improved. Moreover, using the dental brace provided by the present invention, the user can take it off and put it on as needed. For example, the user can take it off when eating and put it on after washing, which is convenient and hygienic.

[0020] In the preferred embodiment of the present application, correction can also be performed for users who have uneven teeth during the tooth replacement period, by setting a tooth gap placeholder at the position of the erupting tooth, and its size is set so as not to contact the gingival end surface of the erupting tooth; in a further preferred scheme, the placeholder is also designed to be adaptively cut according to the growth progress of the erupting tooth, so as to avoid contact with the erupting tooth. The above-mentioned braces can better meet the needs of tooth correction during the tooth replacement period, manage the tooth gaps for users in the tooth replacement period, and avoid the situation where the user has uneven teeth due to too small tooth gaps during the tooth replacement process, so that the user has neatly arranged teeth when the teeth grow, and the user's teeth are beautiful and natural after they grow. Therefore, the present invention can correct the teeth of the user during the tooth replacement period, effectively prevent the user's teeth from growing crooked during the tooth growth process, and fundamentally solve the problems of crooked teeth and uneven teeth.

[0024] Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited to the specific implementation disclosed below.

[0025] The present application provides a dental brace. The dental brace of the present invention is described in detail below in conjunction with specific embodiments and drawings.

[0026] In daily life, there are many situations in which gaps appear between grown teeth. For example, gaps appear between grown teeth due to missing teeth, such as Figure 1 As shown, Figure 1 This is a schematic diagram of the deformation of teeth when a user has missing teeth. Or due to tooth decay, gaps formed after bacteria corrode the teeth, etc.; there are many other situations that cause gaps in already grown teeth, which will not be repeated here. The dental brace provided in this application is provided with a tooth gap placeholder at the position corresponding to the tooth gap to improve the correction effect of the dental brace.

[0027] Figure 2 FIG. 1 is a schematic diagram of a dental brace according to a first embodiment of the present invention.

[0028] like Figure 2 As shown, the dental brace 1 of this embodiment includes a correction brace 12 and a tooth gap placeholder 13. The correction brace 12 constitutes the main part of the dental brace 1, and can also be called the dental brace body; in this application, the dental brace is used to refer to the entire correction brace provided in this embodiment including the tooth gap placeholder 13, and the correction brace specifically refers to the main part of the dental brace except the tooth gap placeholder, and this way of referring is only for the convenience of expression.

[0029] The orthodontic brace 12 is specially modeled and customized according to the use requirements of a specific user, and includes a groove 121, a groove inner wall 122 and a groove outer wall 123. The groove 121 is made according to the position, shape and size of the user's teeth to form an overall inner contour that matches the overall shape of the user's teeth, and the surface of the inner contour is the groove inner wall 122. The groove outer wall 123 forms the outer surface of the orthodontic brace 12, and it is necessary to consider aesthetics and minimize the impact on the use of teeth.

[0030] The dental brace is also provided with a tooth gap placeholder 13. The tooth gap placeholder 13 is provided in the groove 121 of the correction brace 12, and its specific setting position is set according to the position of the user's tooth gap. The shape and size of the tooth gap placeholder 13 are set according to the shape and size of the tooth gap corresponding to the tooth gap placeholder 13. When the user wears the dental brace 1, the tooth gap placeholder 13 enters and occupies the corresponding tooth gap.

[0031] There are many reasons for the formation of tooth gaps. Generally, placeholders are set up to fill the tooth gaps caused by missing teeth due to various reasons. Figure 2 The gap placeholder 13 provided in the orthodontic braces 12 shown is formed for missing teeth, and therefore, its contour shape and size are similar to the contour and size of the missing teeth. Of course, the gap placeholder 13 is not required to be completely complementary to the contour of the gap caused by the missing teeth, because it is technically difficult to achieve, and the gap placeholder 13 needs to be more conveniently embedded in the space of the tooth gap when the orthodontic braces 12 are worn. Making it to be exactly the same in size will make the orthodontic braces 12 difficult to wear; but on the other hand, if the contour of the gap placeholder 13 is too different from the gap, it will affect the correction effect; therefore, the size and contour design of the gap placeholder 13 should take into account the contradictions between the above two aspects and select appropriate intermediate parameters.

[0032] The first embodiment is mainly aimed at the situation where users whose teeth have grown need to wear the dental braces due to missing teeth. Although the user's teeth are neatly arranged, due to some reasons, the user cannot have dentures or implants in time. In order to avoid the situation where the user's teeth are deformed from the tooth gap due to missing teeth, the user needs to wear the dental braces 1. At this time, the groove 121 can be set according to the position, shape and size of each tooth of the user, so that the inner wall 122 of the groove and the outer wall 123 of the groove fit each tooth of the user. The tooth gap placeholder 13 can just contact the teeth on both sides of the tooth gap, avoiding the situation where the teeth of the user are offset in the direction of the tooth gap due to the action of the inter-tooth force while waiting for dentures or implants.

[0033] Optionally, the number of the tooth gap placeholders 13 is one or more. For example, when there is only one tooth gap that needs to be occupied among the teeth of the user, the number of the tooth gap placeholders 13 on the dental brace is set to one. When there are multiple tooth gaps that need to be occupied among the teeth of the user, the number of the tooth gap placeholders 13 on the dental brace is set to multiple.

[0034] When the user has uneven teeth, the groove 121 can be set according to the specific position of the uneven teeth, and the inner wall 122 or the outer wall 123 of the groove can give the uneven teeth an appropriate force to make the uneven teeth shift in the direction of neat arrangement. At this time, the tooth gap placeholder 13 on the dental brace 1 has occupied the tooth gap of the user, and the tooth gap placeholder 13 can just contact the teeth on both sides of the tooth gap, avoiding the situation that the user's teeth are shifted in the direction of the tooth gap due to the force between the teeth during the tooth correction process. Therefore, during the tooth correction process, the user's teeth will not shift in the direction of the tooth gap due to the action of the tooth gap placeholder, and at this time, the uneven teeth will move in the direction of neat arrangement under the action of the force of the inner wall 122 or the outer wall 123 of the groove, so that the roots of the user's teeth will also move in the direction of neat arrangement during the tooth correction process, effectively preventing the user's teeth from growing crooked during the tooth growth process, and thus fundamentally solving the problems of crooked teeth and uneven teeth.

[0035] Optionally, when the misaligned teeth are close to the neat position, the groove 121 can be directly set at a position where the teeth can be neatly arranged. At this time, the user can correct the misaligned teeth with one dental brace. When the misaligned teeth are far from the neat position, multiple different dental braces 1 can be used to gradually correct the teeth. The grooves 121 of the multiple different dental braces are closer to the neat position. According to the user's tooth arrangement, the multiple different dental braces can be 2, 3 or N. During the teeth correction process, the user can gradually replace the multiple different dental braces to make the user's teeth closer and closer to the neat position until the teeth are neatly arranged.

[0036] Optionally, the tooth gap placeholder and the orthodontic braces may be formed at one time by 3D printing technology or a similar technology, or the tooth gap placeholder and the orthodontic braces may be connected by an anchoring process.

[0037] Optionally, the material of the tooth gap placeholder includes resin material.

[0038] Optionally, the material of the orthodontic braces includes resin or elastic polymer material.

[0039] In the second embodiment, when the user is in the period of tooth replacement, the tooth gap may also be the gap between the user's deciduous teeth or the gap formed by the loss of deciduous teeth during the period of tooth replacement. At this time, the dental brace sets a tooth gap placeholder 13 according to the gap between the user's deciduous teeth and the gap formed by the loss of teeth. The tooth gap placeholder 13 is set in accordance with the position, shape and size of the tooth gap of the teeth to be corrected. When the dental brace 1 is worn, the tooth gap placeholder 13 just enters and occupies the corresponding tooth gap. And the tooth gap placeholder 13 does not contact the user's gums. If the erupted teeth of the user in the period of tooth replacement are not aligned,

[0040] The groove 121 can be designed according to the specific position of the unevenly arranged teeth, so that the inner wall 122 or the outer wall 123 of the groove can give the unevenly arranged teeth appropriate force, so that the unevenly arranged teeth are shifted in the direction of neat arrangement. At this time, the tooth gap placeholder 13 on the dental brace 1 has occupied the tooth gap of the user, and the tooth gap placeholder 13 can just contact the teeth on both sides of the tooth gap, avoiding the situation that the user's teeth are shifted in the direction of the tooth gap due to the force between the teeth during the tooth correction process. Therefore, during the tooth correction process, the user's teeth will not be shifted in the direction of the tooth gap due to the action of the tooth gap placeholder. At this time, the uneven teeth will be moved in the direction of neatly arranged teeth under the action of the force of the inner wall 122 or the outer wall 123 of the groove, and the roots of the teeth will also move in the direction of neat arrangement, thereby correcting the user's jaw.

[0041] Optionally, when the misaligned teeth are close to the neat position, the tooth groove 121 can be directly set at a position where the teeth can be neatly arranged. At this time, the user can correct the misaligned teeth with one dental brace. When the misaligned teeth are far away from the neat position of the teeth, a multi-stage dental brace 1 can be used. The multi-stage dental brace is a dental brace with multiple tooth grooves 121 getting closer and closer to the neat position of the teeth. According to the user's tooth arrangement, the multi-stage dental brace can be 2, 3 or N. During the teeth correction process, the user can gradually replace the multi-stage dental brace to make the user's teeth closer and closer to the neat position of the teeth until the teeth are neatly arranged. When the tooth gap placeholder 13 is in the position of the gap caused by the tooth falling, the tooth gap placeholder at this position can be cut according to the growth height of the erupting teeth to avoid contact with the erupting teeth. Thereby, the growth of the erupting teeth will not be affected. Moreover, when users in the period of replacement teeth use the dental brace 1, the gaps between the teeth of the users can be effectively managed, and the situation that the size of the erupted teeth is larger than the original size of the deciduous teeth and squeezes the adjacent deciduous teeth can be avoided. The teeth of users in the period of replacement teeth can be further effectively corrected, and the situation that the teeth of users in the process of tooth growth can be effectively prevented, thereby fundamentally solving the problems of crooked teeth and uneven tooth arrangement.

[0042] Optionally, when the tooth gap placeholder 13 is located at the gap created by tooth loss, the user can perform adaptive cutting according to the growth progress of the erupting tooth so that the placeholder will not conflict with the user's erupting tooth, thereby not affecting the growth of the erupting tooth.

[0043] Optionally, when the tooth gap placeholder 13 is at the position of the gap caused by tooth falling, a layered structure is set for the tooth gap placeholder 13 at this position, and the user can remove the layer toward the erupting tooth according to the growth height of the erupting tooth. The number of removed layers can ensure that the tooth gap placeholder 13 will not conflict with the erupting tooth, thereby not affecting the growth of the erupting tooth.

[0044] Optionally, the connection method of the layered structure of the tooth gap placeholders 13 includes connection by nesting layer by layer, and the specific method of the layer-by-layer nested connection is to set a protrusion on the groove 121 of the corrective braces 12 and at a position corresponding to the user's tooth gap, and to respectively set a groove matching the protrusion and a protrusion matching the groove on both sides of each layer of the tooth gap placeholders with the layered structure, so that the tooth gap placeholders with the layered structure are connected layer by layer in a nested manner.

[0045] Optionally, the layered structure of the tooth gap spacer 13 is connected by screwing layer by layer, such as Figure 3As shown, in this embodiment, the number of layers of the tooth gap placeholders is three layers, and the layer-by-layer screw connection method of the three layers is specifically as follows: a threaded blind hole 1211 is set on the groove 121 of the correction brace 12 and at a position corresponding to the user's tooth gap, and a stud 1312 matching the threaded blind hole 1211 on the groove 121 is set on the first layer of tooth gap placeholders 131 with a layered structure and on the side facing the groove 121. When the stud 1312 of the first layer of tooth gap placeholders 131 is tightened with the threaded blind hole 1211 of the groove 121, the first layer of tooth gap placeholders 131 is just fitted with the groove 121, and a stud 1312 matching the threaded blind hole 1211 on the first layer of tooth gap placeholders 131 is set on the second layer of tooth gap placeholders 132 with a layered structure and on the side facing the first layer of tooth gap placeholders 131. A stud 1322 matching the threaded blind hole 1311 of the second-layer tooth gap placeholder 132 is provided. When the stud 1322 of the second-layer tooth gap placeholder 132 is tightened with the threaded blind hole 1311 of the first-layer tooth gap placeholder 131, the second-layer tooth gap placeholder 132 is just fitted with the first-layer tooth gap placeholder 131. A stud 1332 matching the threaded blind hole 1321 on the second-layer tooth gap placeholder 132 is provided on the side of the third-layer tooth gap placeholder 133 having a layered structure and facing the second-layer tooth gap placeholder 132. When the stud 1332 of the third-layer tooth gap placeholder 133 is tightened with the threaded blind hole 1321 of the second-layer tooth gap placeholder 132, the third-layer tooth gap placeholder 133 is just fitted with the second-layer tooth gap placeholder 132. The three-layer tooth gap placeholders are connected layer by layer by the above-mentioned screw connection method, so that the size of the connected tooth gap placeholders 13 is just not in contact with the gingival end surface of the erupting tooth. When the number of layers of the tooth gap placeholders is other numbers, each layer of tooth gap placeholders is connected layer by layer by the above-mentioned screw connection method until the size of the connected tooth gap placeholders does not contact the gingival end surface of the erupting tooth, and the thickness of the studs, threaded blind holes and each layer of tooth gap placeholders is determined according to actual conditions.

[0046] Although the present invention is disclosed as above in the form of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art may make possible changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims of the present invention.
