Embodiment 1

[0045] like Figure 7 , 9, 10, the technical solution adopted by the present invention is: a kind of traction element for assisting invisible orthodontic treatment of mesial molars, the traction element 3 has a traction element arm 31 and a bonding part 32, and one end of the traction element 3 passes through The bonding portion 32 is fixed on the molar 5 to be moved, and the traction member arm 31 and the bonding portion 32 are fixedly connected, so that the traction member arm 31 and the bonding portion 32 become a rigid body, and the traction member One end of the arm 31 is provided with a mesial hook 34, and the other end is provided with a distal hook 33, and the bonding portion 32 is arranged between the proximal hook 34 and the distal hook 33, and the bonding portion 32 is arranged on Near one end of the far middle hook 33, the near middle hook 34, the far middle hook 33 and the adhesive part 32 are integrally formed, which can be welded or integrally formed. The near ...

Embodiment 2

[0055] like Figure 8-10 As shown, the bonding portion 32 is a hollowed-out metal bottom plate, the hollowed-out metal bottom plate is circular or elliptical, and its lower end is welded to the puller arm 31, and the bonding portion 32 is bonded to the molar by an adhesive. 5, the mouthpiece 1 is provided with a mouthpiece window 6 at the bonding part 32, that is, part of the mouthpiece material is removed, and the size of the mouthpiece window 6 is slightly larger than the hollow metal bottom plate, which can avoid interference with the adhesive when removing and wearing the mouthpiece. The connecting portion 32 will not affect the firmness of the bonding portion 32, and the adhesive is preferably a photocurable composite resin.

Embodiment 3

[0057] like Figure 11-13 As shown, the bonding part 32 is a metal short arm, which is welded or integrally formed with the puller arm. The bonding part 32 is bonded to the buccal surface of the molar 5 through an adhesive, and then the dental brace 1 The metal short arm is wrapped as a whole, eliminating the step of reprocessing the braces, and the adhesive is preferably light-cured composite resin.

[0058] like Figure 14 as shown,

[0059] Also provided is a treatment method using a molar-assisted mesial movement device, the steps of which are as follows:

[0060] a: Obtaining or dental data in the oral cavity;

[0061] b: Determine the impedance center where the molars need to be moved mesially;

[0062] c: design and manufacture invisible aligners and traction parts as mentioned above;

[0063] d: fix the traction member to the patient's mesially moved molars, and at the same time, determine whether to perform cancellous bone resection as required;

[0064] e: Wear...

Abstract

The invention discloses a device for assisting in invisibly correcting to carry out mesial movement of a molar, which comprises a tooth socket, an orthodontic elastic attachment and a traction piece.The traction piece is provided with a traction piece arm and a bonding part; a mesial hook is arranged at one end of the traction piece arm; a distal hook is arranged at the other end of the tractionpiece arm; the bonding part is arranged between the mesial hook and the distal hook; the tooth socket is arranged on upper and lower dentitions in a sleeving mode; a tooth socket opening is formed onthe tooth socket of the opposite jaw dentitions of the mesial moved molar; the tooth socket opening is disposed in the mesial direction of the molar; one end of the orthodontic elastic attachment is connected with mesial hook and the distal hook; and the other end of the orthodontic elastic attachment is connected to the tooth socket opening of the opposite jaw dentitions. The tooth socket can generate a correcting force on teeth, meanwhile, a traction force can also be applied to the traction piece, and under the action of the two forces, the molar can be guaranteed not to be deflected when being moved. The device solves the technical problem that in the prior art, in the process of invisibly correcting to carry out long-distance mesial movement of the molar, mesial inclination of the molar is liable to occur, and the device has a good correcting effect.

Description

technical field [0001] The invention relates to the technical field of oral medicine, in particular to a device and an orthodontic method for assisting invisible orthodontic treatment of mesial molars. Background technique [0002] Orthodontic treatment often encounters the situation that the first molar is missing or seriously damaged and cannot be preserved, such as figure 1 Shown is a schematic representation of missing mandibular first or second molars. When it is clear that the third molar tooth germ exists and is well developed, when designing the orthodontic plan, when choosing the tooth position for tooth extraction, it is often considered to extract the unsuitable first molar, move the second and third molar mesially, and close the first molar Clearance. In addition, for cases of subtractive extraction, moderate molar anchorage and minimal anchorage, it is also necessary to move the molars mesially to close the extraction gap. For the mandible, due to the dense b...
