Description

Technical Field

[0001] The invention relates to the field of oral orthodontics, and in particular to a lingual appliance with a separated auxiliary arch tube hole. Background Art

[0002] In the process of lingual correction, before the correction, the doctor will first develop a correction plan that suits the patient's individual needs based on the patient's dental condition. In some correction plans, the patient's front teeth must be aligned. For lingual correction, alignment is difficult and can easily cause clinical phenomena of uneven incisors of the front teeth. Therefore, an auxiliary arch tube will be added to the correction system to assist in aligning the front teeth.

[0003] As part of the fine adjustment in correction, the stage of aligning the front teeth usually occurs in the later stage of the correction process. At the same time, auxiliary arch tubes need to be added to the brackets to apply force to the teeth through the conduction of the brackets to control the movement of the dentition. This means that when the doctor designs the correction plan in the early stage, he must first determine whether the patient needs to add auxiliary arch tubes in the later stage of correction, so as to design the corresponding bracket structure: if auxiliary arch tubes are needed in the later stage of correction, the installation structure of the auxiliary arch tubes needs to be designed on the brackets in the early stage; if auxiliary arch tubes are not needed, the installation of the auxiliary arch tubes will not be considered in the early stage of the bracket structure design, and only the ordinary bracket structure will be designed.

[0004] This places high demands on the physician's level of correction scheme design. This is because during the correction cycle, although the physician hopes that the correction effect can be achieved as expected through scheme design, the actual correction process often deviates from the expected process due to factors such as the difference between the actual force expression of the correction system and the ideal, individual differences between different patients, and differences in medical levels between different physicians. For example, in some cases, the actual correction process did not meet the initial expectations, and it was not until the later stage of correction that it was discovered that an auxiliary arch tube needed to be temporarily added for alignment or fine adjustment. However, since the corresponding structure was not preset and the corresponding position was not reserved in the early stage of bracket design, the auxiliary arch tube could not be temporarily added to the bracket later, resulting in the inability to make adjustments or alignment later. On the contrary, if the auxiliary arch tube hole is blindly added to the bracket in the early stage of correction, and if the later correction process is as ideal as theoretically expected, the auxiliary arch tube is not actually needed, then the design of the auxiliary arch tube hole on the bracket will appear redundant, increasing the material and manufacturing costs; more importantly, since the auxiliary arch tube hole is convex and its installation position is close to the incisal end of the tooth, there will be a certain occlusal interference with the incisal end of the tooth in the early stage, which will affect the patient's bite and bring unnecessary intraoral discomfort to the patient throughout the correction cycle, resulting in a poor experience of using the orthodontic appliance. Summary of the invention

[0005] To overcome the deficiencies of the prior art, the object of the present invention is to provide a lingual orthodontic appliance with a separable auxiliary arch tube hole, which can solve the problem that the auxiliary arch tube cannot be adjusted in the later stage of the existing lingual orthodontic process.

[0006] The present invention is achieved through the following technical solutions:

[0007] A lingual orthodontic appliance with a separable auxiliary arch tube hole, comprising: a bracket, the bracket having a first bottom surface that fits against the tooth surface, the bracket protruding with a body portion for threading an arch wire, and the bracket not having an auxiliary arch tube hole for installing an auxiliary arch tube; an auxiliary arch tube plate, the auxiliary arch tube plate having a second bottom surface that fits against the tooth surface, the auxiliary arch tube plate being provided with an auxiliary arch tube hole for threading an auxiliary arch tube; the auxiliary arch tube plate being detachably spliced to the bracket, or, the auxiliary arch tube plate being detachably connected to the bracket; correspondingly, the auxiliary arch tube plate is located on the side close to the incisal end of the tooth, and the bracket is located on the side close to the gingival end.

[0008] Further, a first positioning portion is provided on one side of the bracket relative to the auxiliary arch tube plate, and a second positioning portion is provided on one side of the auxiliary arch tube mounting plate relative to the bracket, and the first positioning portion is adapted to be snap-fitted with the second positioning portion to limit the auxiliary arch tube plate.

[0009] Further, the first positioning portion is a positioning groove, and the second positioning portion is a matching positioning buckle; or, the first positioning portion is a positioning buckle, and the second positioning portion is a positioning groove.

[0010] Further, the shape of the positioning groove is any one of a rectangular groove, a wavy groove, a circular groove, a semi-circular groove, an elliptical groove, a horseshoe-shaped groove, a trapezoidal groove, a triangular groove, a polygonal groove, a star-shaped groove or an irregular special-shaped groove.

[0011] Further, the auxiliary arch tube plate and the bracket are connected by fasteners.

[0012] Further, the bracket is a 3D printed part, and the first bottom surface is printed based on the patient's tooth surface morphology; the auxiliary arch tube plate is a 3D printed part, and the second bottom surface is printed based on the patient's tooth surface morphology; when the auxiliary arch tube plate is connected to the bracket, the first bottom surface and the second bottom surface are combined into a surface and jointly adhere tightly to the tooth surface.

[0013] Further, the auxiliary arch tube hole is a strip-shaped through hole; both ends of the strip-shaped through hole in the axial direction are through ends, and it is completely closed in the radial direction; or, both ends of the strip-shaped through hole in the axial direction are through ends, and it has an opening in the radial direction, and the opening is located at the top of the auxiliary arch tube plate in the thickness direction.

[0014] Further, the lingual appliance with a split auxiliary arch tube hole further comprises: an auxiliary arch tube; the auxiliary arch tube is simultaneously passed through the auxiliary arch tube holes of a plurality of the auxiliary arch tube plates.

[0015] Further, the lingual appliance with a split auxiliary arch tube hole further comprises: an arch wire; an arch wire groove is formed on the body of the bracket, and the arch wire is clamped in the arch wire groove.

[0016] Further, the auxiliary arch tube is slidably passed through the auxiliary arch tube plate.

[0017] Compared with the prior art, the beneficial effects that the present invention can achieve are as follows:

[0018] In the past, when designing an auxiliary arch tube hole on a bracket, considering the requirements for the stable formation of the bracket and the certain wall thickness of the auxiliary arch tube hole itself, the auxiliary arch tube hole would protrude in the thickness direction relative to the bracket base plate. At the same time, the auxiliary arch tube hole is close to the incisal end of the tooth, which is likely to cause occlusal interference and bring a strong foreign body sensation.

[0019] In the present invention, regardless of whether it is determined in the early stage of formulating the orthodontic treatment plan that the auxiliary arch tube will be used in the later stage, during the structural design stage of the bracket, there is no need to consider the installation structure and installation position for reserving the auxiliary arch tube hole. Only a first positioning structure needs to be set on one side of the bracket close to the incisal end of the tooth, and a second positioning structure is correspondingly set on the auxiliary arch tube plate. Since the auxiliary arch tube plate and the bracket are assembled or connected in the tooth surface direction, the first positioning structure will only be reflected in the length direction of the bracket, rather than in the thickness direction of the bracket. That is, there will be no height protrusion or thickness increase on the bracket base plate, so that it is not easy to affect the patient's occlusion after the bracket is bonded and will not bring a strong foreign body sensation.

[0020] In the early stage of orthodontic treatment, the doctor only needs to bond the bracket of the present invention to the tooth surface, and the auxiliary arch tube plate does not need to be bonded. As the orthodontic treatment progresses, the doctor continuously observes the movement of the dental arch throughout the process. Until multiple sets of arch wires are replaced, in the later stage of orthodontic treatment, a secondary evaluation can be made according to the actual orthodontic treatment effect at present: if it is necessary to add an auxiliary arch tube to align the anterior teeth after the secondary evaluation, apply an adhesive on the second bottom surface of the auxiliary arch tube plate, fit the auxiliary arch tube plate to the bracket to obtain a unique determined position (since the volume of the auxiliary arch tube plate is too small, it will be difficult to accurately position if directly bonded or bonded through a positioning guide plate), and bond it tightly to the patient's tooth surface, and then pass the auxiliary arch tube through the auxiliary arch tube hole, so as to achieve the alignment of the anterior teeth or the fine movement of the dental arch in the later stage of orthodontic treatment. If the goal of aligning the anterior teeth can be achieved in advance before the end of orthodontic treatment, the auxiliary arch tube plate can be removed from the tooth surface in advance, so that the patient is affected as little as possible by the foreign body sensation and occlusal interference of the auxiliary arch tube hole.

[0021] If no auxiliary arch tube needs to be added after the secondary evaluation, the auxiliary arch tube plate does not need to be bonded throughout the orthodontic treatment. Only the brackets need to be bonded to complete the correction. In this way, the patient will not be affected by the foreign body sensation of the auxiliary arch tube and occlusal interference throughout the process, and the experience will be greatly improved. At the same time, the material and manufacturing costs brought by the redundant auxiliary arch tube plate can be saved.

[0022] When using the lingual orthodontic appliance of the present invention, the accuracy requirements for the design of the preliminary orthodontic treatment plan can be greatly reduced, so that more doctors with different treatment levels or styles can be compatible, giving doctors a greater treatment space. Doctors can flexibly install or remove the auxiliary arch tube plate and auxiliary arch tube at any time during the orthodontic treatment. On the premise of ensuring that the patient can align the anterior teeth and achieve fine movement, the patient is minimally affected by occlusal interference and foreign body sensation, taking into account both the treatment effect and the patient's comfort.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] See also Figures 1-3 The present invention discloses a lingual orthodontic appliance with a detachable auxiliary arch tube hole, comprising: a bracket 10 and an auxiliary arch tube plate 20. The bracket 10 has a first bottom surface that fits the patient's tooth surface shape, and is bonded to the patient's tooth surface by applying an adhesive, and the tooth surface can be the lingual side or the labial side; the bracket 10 does not contain an auxiliary arch tube hole 22 for installing an auxiliary arch tube 30, and its bottom plate is only provided with a body 12 for installing an arch wire 40. The auxiliary arch tube plate 20 has a second bottom surface that fits the patient's tooth surface, and is bonded to the patient's tooth surface by an adhesive; the auxiliary arch tube plate 20 is provided with an auxiliary arch tube hole 22 for passing the auxiliary arch tube 30. The auxiliary arch tube plate 20 can be detachably spliced ​​to the bracket 10, or the auxiliary arch tube plate 20 can be detachably connected to the bracket 10; the relative position relationship between the two is that the auxiliary arch tube plate 20 is located on the side close to the incisal end of the tooth 50, and the bracket 10 is located on the side close to the gingival end.

[0038] The bracket 10 and the auxiliary arch tube plate 20 can be spliced through a positioning structure. Specifically, referring to Figures 4-7 , a first positioning portion 11 is provided on one side of the bracket 10 relative to the auxiliary arch tube plate 20. Correspondingly, a second positioning portion 21 is provided on one side of the mounting plate of the auxiliary arch tube 30 relative to the bracket 10. Alternatively, a first positioning portion 11 is provided on one side of the mounting plate of the auxiliary arch tube 30 relative to the bracket 10, and a second positioning portion 21 is provided on one side of the bracket 10 relative to the mounting plate of the auxiliary arch tube 30.

[0039] Further preferably, the first positioning portion 11 is a positioning groove, and the second positioning portion 21 is a matching positioning buckle; alternatively, the first positioning portion 11 is a positioning buckle, and the second positioning portion 21 is a matching positioning groove. The shape of the positioning groove is not limited and can be any one of a rectangular groove, a wavy groove, a circular groove, a semi-circular groove, an elliptical groove, a horseshoe groove, a trapezoidal groove, a triangular groove, a polygonal groove, a star-shaped groove or an irregular special-shaped groove, and can be any shape that can realize the positioning between the auxiliary arch tube plate 20 and the bracket 10.

[0040] As an alternative implementation, the auxiliary arch tube plate 20 and the bracket 10 can also be connected by fasteners. For example, corresponding insertion posts and insertion holes are provided on the bracket 10 or the auxiliary arch tube plate 20, or two clamping portions and a clamped member, etc., as long as the structure that can realize the detachable connection between the two can be used.

[0041] In the past, when formulating a treatment plan in the early stage of orthodontics, if it was considered that the patient needed to use the auxiliary arch tube 30 to align the anterior teeth in the later stage, it was necessary to design an auxiliary arch tube hole 22 on the bracket 10. For example, through the process of 3D printing or metal casting, the bracket 10 containing the auxiliary arch tube hole 22 was integrally formed. Considering the requirements for the stable formation of the bracket 10 and the certain wall thickness of the auxiliary arch tube hole 22 itself, the auxiliary arch tube hole 22 would protrude in the thickness direction relative to the bottom plate of the bracket 10. At the same time, the auxiliary arch tube hole 22 was close to the incisal edge of the tooth 50, which was likely to cause occlusal interference and bring a large sense of foreign body. In this way, the patient's occlusion would be affected throughout the orthodontic treatment, and the auxiliary arch tube hole 22 could not be cancelled halfway. In some other cases, when formulating a treatment plan in the early stage, theoretically, the auxiliary arch tube 30 was not needed in the later stage. In order to ensure that the patient's occlusion was not affected and to take into account comfort, the doctor usually did not consider the auxiliary arch tube 30 in the design stage of the bracket 10; however, as the orthodontic treatment progressed, sometimes it was found that the treatment effect did not proceed as expected. It was temporarily found in the later stage of orthodontics that the auxiliary arch tube 30 needed to be worn for adjustment, but since the installation structure and installation position of the auxiliary arch tube 30 were not designed on the bracket 10 in the early stage, the patient could not wear the auxiliary arch tube 30, and the purpose of aligning the anterior teeth could not be achieved.

[0042] In the present invention, when formulating a treatment plan in the early stage, regardless of whether an auxiliary arch tube 30 is needed in the later stage of orthodontics, during the structural design stage of the bracket 10, there is no need to consider the installation structure and installation position of the auxiliary arch tube hole 22. Only a first positioning portion 11 needs to be provided on one side of the bracket 10 close to the incisal edge of the tooth 50. Correspondingly, a second positioning portion 21 is provided on the auxiliary arch tube plate 20. Since the auxiliary arch tube plate 20 and the bracket 10 are joined or connected in the tooth surface direction, the first positioning portion 11 will only be reflected in the length direction of the bracket 10 and will not be reflected in the thickness direction of the bracket 10. That is, the bottom plate of the bracket 10 will not have any height protrusion or thickness increase, so that it is not easy to affect the patient's occlusion after the bracket 10 is bonded and will not cause a large foreign body sensation.

[0043] In the early stage of orthodontics, the dentist only needs to bond the bracket 10 of the present invention to the tooth surface, and the auxiliary arch tube plate 20 does not need to be bonded temporarily (see Figure 8 ), as the orthodontic treatment progresses, the dentist continuously observes the movement of the dental arch throughout the process. Until multiple arch wires 40 are replaced, in the later stage of orthodontics, a secondary evaluation can be made according to the actual orthodontic effect at present: if it is necessary to add an auxiliary arch tube 30 to align the anterior teeth during the secondary evaluation, then an adhesive can be applied to the second bottom surface of the auxiliary arch tube plate 20 at this time, and the auxiliary arch tube plate 20 is fitted to the bracket 10 to make the auxiliary arch tube plate 20 obtain a unique determined position (since the volume of the auxiliary arch tube plate 20 is too small, it will be difficult to accurately locate if the bonding position is directly determined by visual observation or indirectly bonded through a positioning guide plate), and it is tightly bonded to the patient's tooth surface, and then the auxiliary arch tube 30 is inserted into each auxiliary arch tube hole 22, so that the anterior teeth can be aligned or the dental arch can be finely moved in the later stage of orthodontics. If the goal of aligning the anterior teeth is achieved in advance before the end of orthodontics, the auxiliary arch tube plate 20 can be removed from the tooth surface in advance, so that the patient is less affected by the foreign body sensation of the auxiliary arch tube hole 22 and occlusion interference.

[0044] If it is not necessary to add an auxiliary arch tube 30 during the secondary evaluation, then the auxiliary arch tube plate 20 does not need to be bonded throughout the orthodontic treatment, and only the bracket 10 needs to be bonded to complete the correction. In this way, the patient is not affected by the foreign body sensation of the auxiliary arch tube 30 and occlusion interference throughout the process, and the experience is greatly improved. At the same time, the material and manufacturing costs brought by the redundant auxiliary arch tube plate 20 can be saved.

[0045] When using the lingual orthodontic appliance of the present invention, the accuracy requirement for the early orthodontic treatment plan design can be greatly reduced. In this way, more dentists with different treatment levels or styles can be compatible, giving the dentists a greater treatment space. The dentist can flexibly install or remove the auxiliary arch tube plate 20 and the auxiliary arch tube 30 at any time during the orthodontic treatment. On the premise of ensuring that the patient can align the anterior teeth and achieve fine movement, at the same time, the patient is less affected by occlusion interference and foreign body sensation, taking into account both the treatment effect and the patient's comfort.

[0046] Preferably, the bracket 10 is a 3D printed part, and its first bottom surface is printed and formed based on the tooth surface morphology of the patient, which is a design customized for the patient; the auxiliary arch tube plate 20 is also a 3D printed part, and its second bottom surface is printed and formed based on the tooth surface morphology of the patient, which is also a personalized customized design. When the auxiliary arch tube plate 20 is connected to the bracket 10, the first bottom surface and the second bottom surface are joined together to form a surface and jointly adhere closely to the tooth surface. The bracket 10 and the auxiliary arch tube plate 20 are two parts independently printed and formed by 3D. Therefore, the bracket 10 can be printed separately in the early stage of orthodontics. If the auxiliary arch tube 30 does not need to be installed in the later stage of orthodontics, the printing of the auxiliary arch tube plate 20 can be cancelled, saving material costs and printing costs.

[0047] Preferably, the auxiliary arch tube hole 22 is a strip-shaped through hole, and there are two embodiments of the structural form of the strip-shaped through hole. Embodiment 1: Both ends of the strip-shaped through hole in the axial direction are through ends for passing through the auxiliary arch tube 30; the strip-shaped through hole is completely closed in the radial direction. Embodiment 2: Both ends of the strip-shaped through hole in the axial direction are also through ends, and there is an opening in the radial direction. The opening is located at the top end of the auxiliary arch tube plate 20 in the thickness direction; when installing the auxiliary arch tube 30, the auxiliary arch tube 30 can be gently pressed into the auxiliary arch tube hole 22 from the upper opening.

[0048] Of course, in the orthodontic system, an auxiliary arch tube 30 is also included; refer to Figure 9 , the auxiliary arch tube 30 is simultaneously passed through the auxiliary arch tube holes 22 of multiple auxiliary arch tube plates 20. Further preferably, the auxiliary arch tube 30 is slidably passed through the auxiliary arch tube plate 20. During the alignment of the anterior teeth, the anterior teeth will move, and there is also a relative sliding relationship between the auxiliary arch tube and the bracket.

[0049] Of course, the orthodontic system also includes an arch wire 40. An arch wire groove is provided on the body 12 of the bracket 10, and the arch wire 40 is clamped in the arch wire groove. The arch wire 40 plays a role in applying the main orthodontic force, while the auxiliary arch tube 30 plays an auxiliary force application role. The two form a double-wire structure to jointly control the movement of the dental arch and achieve fine adjustment.

[0050] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required by the present invention.
