Description

Technical Field

[0001] The present invention relates to the technical field of orthodontics, and particularly to a screw invisible aligner and a method for orthodontic treatment of teeth. Background Art

[0002] Metal bracket aligners are orthodontic appliances with a long history. They are relatively economical in price, but have a high operation difficulty, require a high level of skill from orthodontists, and also a high degree of patient cooperation. Moreover, patients feel very uncomfortable, which affects eating and aesthetics, and it is relatively difficult to perform oral hygiene care during orthodontics. Invisible transparent bracketless aligners overcome the above problems. Patients can remove and wear the aligners by themselves, which is convenient for maintaining oral hygiene and has a higher aesthetic degree. However, when the treatment effect of the invisible aligner reaches about 80%, about 20% of cases cannot be completed. Currently, the invisible aligner has a slow correction speed, a long treatment cycle, the correction force is an intermittent force and cannot achieve a gentle and continuous correction force. In addition, the current invisible aligner mainly corrects by pressing the teeth to move. For various difficult and complex orthodontic cases such as posterior tooth intrusion, posterior tooth distal movement, traction of inclined and rotated teeth, control of root buccolingual movement, and pushing the teeth to move as a whole buccolingually, the treatment effect of the invisible aligner is not good.

[0003] In the process of implementing the present invention, the inventors found the following problems in the prior art: The existing invisible aligners have a long treatment cycle, and the treatment effects on tooth rotation, crossbite, posterior tooth intrusion, protruding mouth, and root control movement are average. It is even more difficult to move the posterior teeth over a long distance, and it is not applicable to complex orthodontic cases either. Summary of the Invention

[0004] The purpose of the present invention is to provide a screw invisible aligner and a method for orthodontic treatment of teeth, so as to solve the problems of average correction effect, long time, difficult root control, and inapplicability to complex orthodontic cases existing in the existing invisible orthodontic technology.

[0005] The technical solutions adopted by the screw invisible aligner and the method for orthodontic treatment of teeth disclosed by the present invention are as follows:

[0006] A screw invisible aligner includes:

[0007] A transparent dental aligner, which is sleeved on the teeth;

[0008] Attachments, which are bonded to the surface of the required teeth on the labial or lingual side through an attachment guide plate;

[0009] A screw forms a thrust by abutting against the tooth surface or the attachment within a screw kit;

[0010] A screw kit, which is arranged at a corresponding position on the labial or lingual side of the transparent dental aligner, and the screw contacts the tooth or the attachment through the screw kit to form a thrust.

[0011] As a preferred solution, the screw has a diameter of 2 MM, a length of 3 MM, and is made of transparent PPS.

[0012] As a preferred solution, the screw stopper kit has a diameter of 3 MM and is made of transparent PPS.

[0013] As a preferred solution, the number of the attachments is multiple, and they are respectively bonded to the teeth to be moved. The number of the screws is multiple, and they are inserted into the screw kit. The number of the screw kits is equal to the number of the screws, and they are respectively bonded to the corresponding transparent dental aligners of each tooth to be moved.

[0014] As a preferred solution, the transparent dental aligner is made of transparent material TPU.

[0015] A method for orthodontics of a screw invisible orthodontic appliance, using the above screw invisible orthodontic appliance for orthodontics, the steps include:

[0016] According to the mouth shape and the shape and size of the teeth, by making dental models, generating 3D images through CBCT scanning, and oral optical scanning to prepare transparent dental aligners;

[0017] According to the mouth shape and the shape and size of the teeth, by making dental models, generating 3D images through CBCT scanning, and oral optical scanning to set the positions of the screws and attachments, as well as the shape of the attachments, and bonding the attachments to the labial or lingual surface of the required teeth through an attachment guide plate with an adhesive, and drilling and bonding the screws and screw kits to the transparent dental aligners;

[0018] Put the transparent dental aligner on the teeth;

[0019] After a correction period, adjust the positions, forms, and numbers of the attachments and screws;

[0020] Repeat the previous step until the correction is completed.

[0021] As a preferred solution, the screw kit is arranged at the corresponding position on the labial or lingual side of the transparent dental aligner, and the screw touches the tooth or the attachment through the screw kit to form a thrust force, so that the tooth moves in the labial or lingual direction.

[0022] As a preferred solution, the attachment is bonded to the labial or lingual side of the required tooth, the screw and the screw kit are arranged at the corresponding position on the labial or lingual side of the transparent dental aligner, and the screw touches the tooth or the attachment through the screw kit to form a thrust force, so that the tooth moves in the horizontal mesial-distal direction.

[0023] As a preferred embodiment, the attachment is bonded to the labial side or lingual side of the required tooth, and the screw and screw kit are arranged at the corresponding positions on the labial side or lingual side of the transparent braces. The screw contacts the tooth or attachment through the screw kit to form a thrust, so that the tooth moves in the vertical direction.

[0024] As a preferred embodiment, the screws and screw kits are arranged at corresponding positions on the labial side or lingual side of the transparent braces. The screws contact the teeth or accessories through the screw kit to form thrust, causing the teeth to rotate clockwise or counterclockwise.

[0025] As a preferred embodiment, the screws and screw kits are arranged at corresponding positions on the labial side or the lingual side of the transparent braces. The screws contact the teeth through the screw kits to form thrust, and the root apex of the teeth moves toward the labial side or the lingual side through the lever principle.

[0026] The beneficial effects of a screw invisible brace and a teeth correction method disclosed by the present invention are: the screw contacts the teeth or accessories, and the thrust is formed by rotating the screw, thereby providing various continuous, precise, and adjustable correction forces, so that the teeth can move in multiple directions to achieve teeth correction. The device is widely applicable to all correction cases, including malocclusion, tooth gaps, and early childhood correction, especially various difficult and complex oral correction cases that are generally recognized at this stage, such as posterior teeth intrusion, posterior teeth movement to the distal, traction and tilting of teeth, control of buccal and lingual movement of tooth roots, and pushing the entire tooth to move to the buccal and lingual sides.

[0027] The screws contact the teeth or accessories, and the force is increased by rotating the screws to form a thrust, providing greater traction than existing invisible braces and significantly shortening the treatment cycle.

[0028] The screw contacts the tooth or accessory through the kit, and the screw can accurately control the force inside the kit to achieve precise tooth movement.

[0029] The screws contact the teeth or accessories, and the thrust is formed by rotating the screws. Setting multiple screws can make the teeth rotate quickly, solving the problem of invisible braces having no torque on the teeth.

[0030] The screw contacts the tooth or the attachment, and the force is applied by rotating the screw to form a thrust. Setting multiple screws can make the tooth as a whole move from the labial side to the lingual side. Or the crown of the tooth does not move, and the root tip moves from the labial side to the lingual side to achieve root control, solving the problem of insufficient root control of teeth by invisible correction.

[0046] The present invention will be further described and explained below in conjunction with specific embodiments and the accompanying drawings of the specification:

[0047] A screw 3 invisible aligner, comprising a transparent dental appliance 2 and a screw 3. The transparent dental appliance 2 is sleeved on the teeth 1, and the screw 3 is disposed on the labial or lingual side of the transparent dental appliance 2 through drilling and bonding; the screw 3 abuts against the teeth 1 to form a thrust force.

[0048] The transparent dental appliance 2 is the main tool for invisible teeth 1 correction and is inseparable from the correction effect. The transparent dental appliance 2 mainly functions to fix and support the screw 3

[0049] The screw 3 is adhesively disposed on the labial or lingual side of the transparent dental appliance 2, and controlling the force applied to the screw 3 can precisely control the force applied to the teeth 1.

[0050] This embodiment 1

[0051] Please refer to Figure 1 、 Figure 2 and Figure 3 , the screw 3 kit, perpendicular to the surface of the transparent dental appliance 2, is disposed at a position corresponding to the buccal side of the transparent dental appliance 2, and the screw 3 abuts against the buccal surface of the teeth 1 through the screw 3 kit. Tightening the screw 3 generates a thrust force to move the teeth 1 in the lingual direction. The first direction A is the direction of the teeth 1 from the labial side to the lingual side.

[0052] The screw 3 kit, perpendicular to the surface of the transparent dental appliance 2, is disposed at a position corresponding to the lingual side of the transparent dental appliance 2, and the screw 3 abuts against the lingual surface of the teeth 1 through the screw 3 kit. Tightening the screw 3 generates a thrust force to move the teeth 1 in the labial direction. The second direction B is the direction of the teeth 1 from the lingual side to the labial side.

[0053] Embodiment 2

[0054] There are multiple screw 3 kits and the corresponding number of screws 3. The first screw 3 kit, perpendicular to the surface of the transparent dental appliance 2, is disposed at a position corresponding to the mesial side near the midline on the labial side of the transparent dental appliance 2, and the screw 3 abuts against the lingual surface of the teeth 1 through the screw 3 kit. The second screw 3 kit is disposed at a position corresponding to the distal side of the midline on the lingual side of the transparent dental appliance 2, and the screw 3 abuts against the lingual surface of the teeth 1 through the screw 3 kit. Tightening the screw 3 generates a thrust force to rotate the teeth 1 in the mesial clockwise direction. The third direction C is the direction of the teeth 1 rotating in the mesial clockwise direction.

[0055] A plurality of screw 3 kits and a corresponding number of screws 3 are required. The first screw 3 kit is perpendicular to the surface of the transparent braces 2 and is set at a position corresponding to the mesial of the midline on the lingual side of the transparent braces 2. The screw 3 is pressed against the lingual surface of the tooth 1 through the screw 3 kit. The second screw 3 kit is set at a position corresponding to the distal of the midline on the labial side of the transparent braces 2. The screw 3 is pressed against the labial surface of the tooth 1 through the screw 3 kit. Tightening the screw 3 generates thrust, causing the tooth 1 to rotate counterclockwise toward the mesial. The fourth direction D is the counterclockwise rotation of the tooth 1 toward the mesial.

[0056] like Figure 4 and Figure 5 As shown, a plurality of screws 3 are arranged on the lingual side and labial side of the corresponding teeth 1 to be corrected by the transparent braces 2, and the screws 3 contact the mesial and distal positions of the teeth 1, and at the same time push the teeth 1 to form a rotational force.

[0057] Example 3

[0058] The attachment 4 is bonded to the labial surface of the required tooth 1, and the screw 3 set is parallel to the surface of the transparent braces 2 and is set at a position corresponding to the mesial of the attachment 4 on the labial side of the transparent braces 2. The screw 3 is pressed against the surface of the attachment 4 through the screw 3 set. Tightening the screw 3 generates a thrust to move the tooth 1 in the direction distal to the midline. The fifth direction E is the direction distal to the midline of the tooth 1.

[0059] The attachment 4 is bonded to the labial surface of the required tooth 1, and the screw 3 set is parallel to the surface of the transparent braces 2 and is set at a position corresponding to the distal end of the attachment 4 on the labial side of the transparent braces 2. The screw 3 is pressed against the surface of the attachment 4 through the screw 3 set. Tightening the screw 3 generates a thrust to move the tooth 1 toward the mesial direction of the midline. The sixth direction F is the direction of the tooth 1 from the mesial direction of the midline.

[0060] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the attachment 4 is bonded to the labial side or the lingual side of the tooth 1 that needs to be corrected, and the screw 3 is bonded to the position of the transparent brace 2 corresponding to the attachment 4. The screw 3 contacts the attachment 4 to move the tooth 1 in the horizontal direction.

[0061] Example 4

[0062] Attachment 4 is bonded to the labial surface of the required tooth 1. The screw 3 kit is parallel to the surface of the transparent dental appliance 2 and is set at the corresponding position on the labial side of the transparent dental appliance 2 between the attachment 4 and the occlusal surface of the tooth 1. The screw 3 abuts against the surface of the attachment 4 through the screw 3 kit. Tightening the screw 3 generates a thrust force to move the tooth 1 in the direction parallel to the midline and towards the root tip. The seventh direction G is the direction of the tooth 1 from the occlusal surface towards the root tip.

[0063] Attachment 4 is bonded to the labial surface of the required tooth 1. The screw 3 kit is parallel to the surface of the transparent dental appliance 2 and is set at the corresponding position on the labial side of the transparent dental appliance 2 between the attachment 4 and the gingiva. The screw 3 abuts against the surface of the attachment 4 through the screw 3 kit. Tightening the screw 3 generates a thrust force to move the tooth 1 in the direction parallel to the midline and towards the occlusal surface. The eighth direction H is the direction of the tooth 1 from the root tip towards the occlusal surface.

[0064] As Figure 11 、 Figure 12 and Figure 13 shown, the attachment 4 is set to be bonded to the labial or lingual side of the tooth 1 to be corrected, and the screw 3 is bonded to the position on the transparent dental appliance 2 corresponding to the attachment 4. The screw 3 abuts against the attachment 4 to move the tooth 1 in the vertical direction.

[0065] Embodiment 5

[0066] As Figure 14 shown, multiple screws 3 are set on the lingual and labial sides of the teeth 1 to be corrected corresponding to the transparent dental appliance 2. The first screw 3 abuts against the occlusal end of the labial side of the tooth 1 to be corrected, and the second screw 3 abuts against the root tip towards the gingival end of the lingual side of the tooth 1 to be corrected. Using the lever principle, the two screws 3 apply force simultaneously to keep the occlusal end of the tooth 1 stationary and move the root tip towards the labial side.

[0067] As Figure 14 shown, multiple screws 3 are set on the lingual and labial sides of the teeth 1 to be corrected corresponding to the transparent dental appliance 2. The first screw 3 abuts against the root tip towards the gingival end of the lingual side of the tooth 1 to be corrected, and the second screw 3 abuts against the occlusal end of the labial side of the tooth 1 to be corrected. Using the lever principle, the two screws 3 apply force simultaneously to keep the occlusal end of the tooth 1 stationary and move the root tip towards the lingual side.

[0068] Different from the prior art, the above technical solutions have the following technical effects:

[0069] 1. Through the thrust force generated by the screw 3 on the tooth 1 and the attachment 4, a continuous, gentle, precise, and controllable thrust force is applied to the tooth 1, greatly shortening the patient's correction time and precisely controlling the movement of the tooth 1.

[0070] 2. Through the thrust force generated by the screw 3 on the attachment 4, a vertical thrust force is applied to the tooth 11, solving the problem that invisible correction cannot push down or raise the tooth 1.

[0071] 3. Even multiple screws 3 can be used such that the crown of the tooth 1 does not move, while the root moves towards the labial or lingual side, solving the pain point of root control in existing arch wire correction and invisible correction.

[0072] 4. The screw 3 can be adjusted by itself. The patient can adjust the correction force of the tooth 1 to a comfortable force for themselves, increasing the comfort of wearing.

[0073] In some other embodiments, the screw 3 has a diameter of 2 MM and a length of 3 MM. The material is transparent PPS, the Chinese name is polyphenylene sulfide. The inner diameter of the screw 3 kit is 2 mm and the outer diameter is 3.4 MM, and the material is transparent PPS, the Chinese name is polyphenylene sulfide

[0074] In some other embodiments, the attachment 4 is made of resin and is bonded to the labial or lingual side of the tooth 1. The length is 2 mm, the width is 2 mm, and the height is 2 mm

[0075] The transparent dental appliance 2 needs to be customized according to the individual oral data of the case: first, obtain the dental and jaw data model of the case, generate a step-by-step orthodontic data model through software simulation, then obtain the physical target models at different stages during the orthodontic process through three-dimensional printing or rapid prototyping technology, and finally press the transparent dental appliance 2 by the method of vacuum hot pressing, and deliver it to the patient after cutting and polishing.

[0076] In the existing orthodontic appliances, it is difficult to push and traction the tooth 1 to move by external force. This solution overcomes the problem of the source of the orthodontic force, and uses the thrust between the screw 3, the tooth 1 and the attachment 4 to continuously push the tooth 1 to move. By turning the screw 3 to change the length of the screw 3 and change the distance between the screw 3, the tooth 1 and the attachment 4, the magnitude of the thrust between the screw 3, the tooth 1 and the attachment 4 can be adjusted, thereby adjusting the magnitude of the acting force for correcting the tooth 1; by adjusting the position and angle of the screw 3, the direction of the thrust for correcting the tooth 1 can be adjusted. Specifically, the screw 3 is fixedly bonded to the transparent dental appliance 2 and can be adjusted accordingly according to the orthodontic cycle and orthodontic effect. The attachment 4 is fixedly bonded to the tooth 1 and the position is fixed.

[0077] By the thrust of the screw 3, the tooth 1 and the attachment 4, a gentle and continuous traction force or thrust is applied to the tooth 1. Using the thrust, the tooth 1 can be pushed in the lingual, labial, vertical, horizontal, clockwise, counterclockwise directions. The crown of the tooth 1 does not move, and the root moves in the lingual and labial directions and other multi-directions. It is applicable to various difficult and complex oral cases such as crossbite of the tooth 1, raising or lowering the tooth 1, rotation of the tooth 1, arch expansion, and bone fenestration. The application range of the indication is wide. This solution applies three different techniques of invisible correction, lingual correction and labial correction, makes use of advantages and avoids disadvantages, and develops a new orthodontic technique.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
