Existing orthodontics are typically customized according to the current orthodontic stage of the patient, with the fixed structure orthodontic slot provided on the appliance and conforming to the target orthodontic tooth profile desired in the current orthodontic stage.

However, when the patient enters the next orthodontic stage, the original customized orthodontic slot loses its orthodontic function and requires the replacement of the orthodontic appliance to be newly customized. Therefore, the orthodontic slot of the fixing structure in the existing orthodontic appliance can only be suitable for a single orthodontic stage, and the problem of great medical material waste and high medical cost can be caused in the whole orthodontic process.

In order to solve the above problems, the present utility model provides an orthodontic appliance. The dental appliance is provided with different dental socket parts, the different dental socket parts are connected with each other by a connecting structure, and all the dental socket parts corresponding to the different dental socket parts are combined into a complete dental socket. Meanwhile, an adjusting component is arranged in the connecting structure, and can change the combined shape of the complete straightening groove, so that the complete straightening groove can be matched with different target straightening tooth shapes, the dental appliance can be suitable for a plurality of different dental straightening stages, medical materials are saved, and medical cost is reduced.

In order to facilitate understanding of the structure of the dental appliance, please refer to fig. 1, fig. 1 is a schematic diagram of a first structure of the dental appliance according to the present embodiment. As shown in fig. 1, the dental appliance 10 includes: a first shell section 11, a second shell section 12, and a connection structure 13 connecting the first shell section 11 and the second shell section 12;

the first shell portion 11 includes a first correction slot portion 112 that mates with a first segment of the tooth segment to be corrected, and the second shell portion 12 includes a second correction slot portion 122 that mates with a second segment of the tooth segment to be corrected;

the connecting structure 13 comprises an adjusting assembly 14, the adjusting assembly 14 can adjust the combined shape of the first dental socket subsection 11 and the second dental socket subsection 12; by adjusting the adjustment assembly 14 to the first state, the complete correction slot 115 formed by the combined shape of the first shell section 11 and the second shell section 12 can be made to coincide with the first target correction tooth profile desired to be achieved for the tooth segment to be corrected; the method comprises the steps of,

by adjusting the adjustment assembly 14 to the second state, the complete correction channel 115 formed by the combined shape of the first shell section 11 and the second shell section 12 can be changed from being in line with the first target correction profile to being in line with the second target correction profile to be achieved for the tooth segment to be corrected; wherein the first target correction tooth form and the second target correction tooth form correspond to different correction phases for the tooth segment to be corrected, respectively.

Wherein the first and second shell sections 11, 12 are adjacent and are structurally specific to the first and second segments of the tooth segment to be corrected, respectively. The specific structures of the first dental socket part 11 and the second dental socket part 12 are similar, specifically, a first dental socket part body 111 of the first dental socket part 11 is provided with a first correction groove part 112 matched with a first section of a tooth section to be corrected, and a second dental socket part body 121 of the second dental socket part 12 is provided with a second correction groove part 122 matched with a second section of the tooth section to be corrected. And, when the first and second shell sections 11 and 12 are coupled to each other by the coupling structure 13, the first and second socket sections 112 and 122 together constitute a complete socket 115 for rectifying the tooth segment to be rectified.

Wherein, the correction groove shape of the first correction groove and the second correction groove is matched with the tooth shape of the tooth section to be corrected of the patient. And, the first orthodontic slot and the second orthodontic slot may be personalized according to different tooth shapes and orthodontic medical plans.

For example, the first correction slot subsection 112 and the second correction slot subsection 122 may be configured differently according to different dividing manners of the first segment and the second segment of the tooth segment to be corrected, and the specific dividing manners are as follows: the division between incisors and cuspids, the division between cuspids and molars, and the like are not particularly limited herein.

The first orthodontic slot subsection 112 and the second orthodontic slot subsection 122 can also be set based on the degree of abrasion caused by the tooth segment to be corrected to the tooth segment to be corrected only causes abrasion to a certain orthodontic slot subsection, so that only the worn tooth shell subsection needs to be replaced after the tooth segment is worn by the tooth, and the whole tooth segment does not need to be replaced, thereby avoiding material waste caused by abrasion replacement. For example, if a certain section of molar will cause greater wear to the dental appliance, the tooth shell is divided into sections corresponding to the section of molar, and the section of molar will only wear the correction slot sections on the tooth shell section corresponding to the section of molar, but will not wear the correction slot sections of other tooth shell sections, and when the wear is serious, only the tooth shell section corresponding to the section of molar needs to be replaced.

The shapes of the straightening grooves of the first straightening groove section 112 and the second straightening groove section 122 may be set in a matching manner for each tooth to be straightened, may be set according to a standard tooth form, may be set as a simple straightening shape such as a guide groove, or may be set so that the whole straightening groove takes a standard tooth form or a simple straightening shape, and the shapes of the straightening grooves corresponding to the individual teeth may be set in a matching manner, without limitation.

The manner and materials of construction of the first and second orthotic groove sections 112, 122 may be selected according to the requirements. For example, the manufacturing method may be 3D printing or die manufacturing, and the material may be resin, silica gel, metal, alloy, etc., which is not limited herein.

Wherein, connection structure 13 can make first facing subsection 11 and second facing subsection 12 stable connection, promptly under connection structure 13's effect, first correction groove and second correction groove can make up and form stable complete correction groove 115 for after tooth card goes into complete correction groove 115, complete correction groove 115 can not produce the deformation under the effect of tooth, thereby guarantees the normal realization of correction function. To achieve this effect, the connection structure 13 may be made of a material with high strength and high rigidity, or the connection structure 13 may be provided with a structure with stable bearing force, which is not limited herein.

The adjustment function of the complete orthotic tank 115 is then performed by the adjustment assembly 14 comprised by the connection structure 13. Specifically, the adjusting component 14 acts on the first dental socket part 11 and the second dental socket part 12 simultaneously, so that the combined shape between the first dental socket part 11 and the second dental socket part 12 can be relatively changed, and the relative positions of the first correction groove and the second correction groove are driven to be changed, so that the combined shape of the complete correction groove 115 is adjusted.

The basic dental appliance 10 provided above for the present embodiment, the dental appliance 10 connects the first dental appliance part 11 and the second dental appliance part 12 through the connection structure 13, so that the first dental appliance part and the second dental appliance part are combined to form the complete dental appliance 115, and the adjusting assembly 14 is provided to adjust the combined shape of the complete dental appliance 115, so that the complete dental appliance 115 can be changed to coincide with different target dental appliances, such as from coincide with the first target dental appliance to coincide with the second target dental appliance intended to be corrected. The arrangement of the adjustable structure enables the dental appliance to be suitable for different dental correction stages, thereby avoiding material loss caused by replacement of the dental appliance and reducing medical cost. Meanwhile, the sectional structure of the dental appliance is convenient to replace, when the teeth are worn, only the worn tooth socket parts are needed to be replaced, and the whole dental appliance does not need to be replaced after the teeth are worn, so that material loss is further avoided.

It should be clear that the first target correction tooth profile and the second target correction tooth profile are merely descriptions of two adjacent correction phases represented in correction targets of different phases, and in actual use, generally include a plurality of phases corresponding to different correction targets respectively; the embodiments of the present utility model and the claims obviously cover a variety of situations involving multiple stages of correction. The appliance 10 may be continuously adapted to the corrective objectives of different corrective phases to thereby accommodate the corrective objectives of different corrective phases.

It should be clear that this embodiment is taken as a basic implementation of the dental appliance 10 according to the present utility model, only two adjacent dental socket parts are exemplified, in a specific implementation process, more dental socket parts may be further provided on the basis of the first dental socket part 11 and the second dental socket part 12, and each two adjacent dental socket parts are connected with each other through the connection structure 13, and meanwhile, the shape of the correction slot formed by the correction slot parts of each two adjacent dental socket parts can be adjusted through the adjustment structure, and the specific structure is similar to the basic implementation described above, so that redundant description is not made here.

For example, there may be entirely a three-piece dental appliance comprising a first shell section, a second shell section, and a third shell section; the embodiments or claims of the present utility model now describe the partial structure of the three-stage dental appliance, which is also within the scope of the utility model as contemplated and understood by the present utility model as extracting two adjacent units therefrom for introduction and protection. Further, four-segment, five-segment, N-segment dental appliances are within the broad scope of the present utility model. It is obvious that as the most basic construction form, the two-stage dental appliance can cover all the features of the above-mentioned forms, and thus, other examples are not listed, and the present utility model is merely exemplified by the two-stage dental appliance.

In addition, in a specific implementation process, more specific setting can be performed on the basis of the dental appliance 10, or other feasible structures can be added, so that more functions or performances can be obtained, and the requirements of different application scenes can be met. The basic dental appliance 10 illustrated in fig. 1 is described in further detail below based on its construction to provide a thorough understanding of the dental appliance 10 provided by the present utility model.

In the dental appliance 10 shown in fig. 1, the adjusting means 14 adjusts the combined shape of the first and second shell sections 11, 12 based on the connecting structure 13, so that the connecting structure 13 is required to enable both the first and second shell sections 11, 12 to maintain a firm connection and the combined shape of the first and second shell sections 11, 12 to be adjusted so that the combined shape of the complete appliance slot 115 can conform to different target appliance tooth shapes. For ease of adjustment, different forms of specific structures may be provided in the connection structure 13 as adjustment references.

One possible configuration is specifically to use the swivel assembly 15 as an adjustment reference for adjusting the combined shape of the first shell section 11 and the second shell section 12. As shown in particular in fig. 1, the connection structure 13 comprises a rotating assembly 15; the rotation assembly 15 allows the first shell section 11 and the second shell section 12 to be relatively rotated by the adjustment assembly 14 based on the rotation assembly 15 and change the combined shape of the complete appliance 115.

Wherein the rotation assembly 15 may be arranged such that the direction of relative rotation of the first shell section 11 and the second shell section 12 is perpendicular to the occlusal direction of the teeth. Illustratively, the first orthodontic slot segment 112 and the second orthodontic slot segment 122 are both horizontally disposed, the occlusal direction of the teeth is the vertical direction, and the rotating assembly 15 is configured to rotate the relative rotational directions of the first shell segment 11 and the second shell segment 12 horizontally to ensure that the first orthodontic slot segment 112 and the second orthodontic slot segment 122 are engaged with each other to match the completed orthodontic slot 115 with the tooth form to be corrected.

There are many specific implementations of the rotating assembly 15, and as shown in fig. 2, fig. 2 is a schematic view of a second structure of the dental appliance. Wherein the rotation assembly 15 includes a rotation shaft 151; the first tooth socket part 11 and the second tooth socket part 12 are respectively sleeved on the rotating shaft 151 in a rotatable manner; when the adjustment assembly 14 is adjusted, the first shell section 11 and the second shell section 12 are rotated relative to each other based on the axis of the rotation shaft 151. Namely, the first shell portion 11 and the second shell portion 12 are formed to be hinged to each other by the rotation shaft 151.

The connection between the rotation shaft 151 and the first and second dental socket parts 11 and 12 may be set such that the first and second dental socket parts 11 and 12 are rotatably fitted on the rotation shaft 151. The rotation shaft 151 may be fixed to the first shell portion 11 or the second shell portion 12, and the corresponding other shell portion may be rotatably fitted over the rotation shaft 151, for example, the rotation shaft 151 may be integrally formed with the first shell portion 11 or the second shell portion 12, which is not limited thereto.

In addition, a relative fixation of the first shell part 11 and the second shell part 12 can also be achieved by means of the rotation shaft 151. As shown in fig. 3, fig. 3 is a schematic view showing a specific structure of a connection portion of the rotation shaft. The rotation shaft 151 has a thread section 152 provided with threads; the first dental socket subsection 11 is provided with a threaded hole 113, and the second dental socket subsection 12 is provided with a through hole 123; the rotation shaft 151 passes through the through hole 123 on the second dental socket part 12, the threaded section 152 of the rotation shaft is in threaded connection with the threaded hole 113 on the first dental socket part 11, and the second dental socket part 12 can be tightly pressed on the first dental socket part 11, so that the first dental socket part 11 and the second dental socket part 12 are relatively fixed under the action of the rotation shaft 151;

alternatively, the second shell portion 12 is provided with a threaded hole 113, and the first shell portion 11 is provided with a through hole 123; the rotation shaft 151 is in threaded connection with the threaded hole 113 on the second dental socket part 12 through the through hole 123 on the first dental socket part 11, and can press the first dental socket part 11 against the second dental socket part 12, so that the first dental socket part 11 and the second dental socket part 12 are relatively fixed under the acting force of the rotation shaft 151.

That is, after the complete correction slot 115 is adjusted to conform to the desired target correction profile by the adjustment assembly 14, the rotation shaft 151 is tightened such that a compressed state is formed between the first shell portion 11 and the second shell portion 12, the force of the rotation shaft 151 providing sufficient friction between the first shell portion 11 and the second shell portion 12 to relatively secure the first shell portion 11 and the second shell portion 12. When the combined shape of the complete correction groove 115 needs to be adjusted again, the rotation shaft 151 is unscrewed, so that the compressed state between the first dental socket part 11 and the second dental socket part 12 can be released, the first dental socket part 11 and the second dental socket part 12 can relatively rotate, and after the first dental socket part 11 and the second dental socket part are rotated to the proper positions, the rotation shaft 151 is screwed again, so that the first dental socket part 11 and the second dental socket part 12 can be relatively fixed again.

The portion where the rotation shaft 151 and the through hole 123 are fitted may be an optical axis or may be a screw section 152. More specifically, the rotation shaft 151 may be a bolt, a screw, or the like. In order to further enhance the effect of the relative fixation, other parts such as a spacer and a nut may be added to the combined structure of the first and second shell parts 11 and 12 and the rotation shaft 151.

In addition, other specific structures may be provided in addition to the adjustment reference by the rotation unit 15, such as a sliding structure for relatively translating the first and second shell portions 11 and 12, and the like, and the present utility model is not limited thereto.

In addition to the fact that the specific structure of the adjusting assembly 14 can take many different forms, the structure of the adjusting assembly 14 itself can be implemented in many different ways, and two specific adjusting assemblies 14 are provided below.

As shown in fig. 4 and 5, fig. 4 is a schematic structural view of one possible adjusting assembly, and fig. 5 is a schematic structural view of the first screw and the second screw. The adjustment assembly 14 includes a threaded sleeve 1411, a first screw 1412, and a second screw 1413; the first screw 1412 and the second screw 1413 each include a threaded rod 1414 and a hinged ball 1415; the threaded rod 1414 of the first screw 1412 and the threaded rod 1414 of the second screw 1413 are respectively in threaded connection with the threaded sleeve 1411; the articulation ball 1415 of the first screw 1412 and the articulation ball 1415 of the second screw 1413 form a ball-and-socket joint with the first shell section 11 and the second shell section 12, respectively;

when the threaded sleeve 1411 is rotated in a first direction, the threaded rod 1414 of the first screw 1412 and the threaded rod 1414 of the second screw 1413 are unthreaded out of the threaded sleeve 1411, causing the combined shape of the complete orthotic slot 115 to change as the threaded sleeve 1411 is rotated in the first direction; when the threaded sleeve 1411 is rotated in a second direction opposite the first direction, the threaded rod 1414 of the first screw 1412 and the threaded rod 1414 of the second screw 1413 are threaded into the threaded sleeve 1411 such that the combined shape of the complete orthotic slot 115 changes as the threaded sleeve 1411 is rotated in the second direction.

In this type of adjustment assembly 14, the threaded sleeve 1411, the first screw 1412 and the second screw 1413 together form a support rod that abuts between the first shell portion 11 and the second shell portion 12, and when the threaded sleeve 1411 is rotated in a first direction, the threaded rods 1414 at both ends of the threaded sleeve 1411 extend, lengthening the support rod formed by the threaded sleeve 1411, the first screw 1412 and the second screw 1413, and abutting the first shell portion 11 and the second shell portion 12 away from each other, thereby changing the combined shape of the complete correction slot 115. When the threaded sleeve 1411 is rotated in the second direction, the threaded rods 1414 at both ends of the threaded sleeve 1411 are retracted, shortening the support rod formed by the threaded sleeve 1411, the first threaded rod 1412, and the second threaded rod 1413, and drawing the first shell section 11 and the second shell section 12 toward each other, thereby changing the combined shape of the complete correction slot 115.
