Embodiment 1

[0048] Example 1: Invisible Correction Method for Type 2 Malocclusion

[0049] First prepare the occlusal repositioning device 1. The occlusal repositioning device 1 is a bilateral resin crown with the correct tooth shape. The length of the occlusal repositioning device 1 on both sides is the sum of the correct teeth of 3 or 4 posterior teeth. The height of the repositioning device 1 increases or decreases depending on the rear occlusal distance obtained after the mandible protrudes forward. The upper part of the occlusal repositioning device 1 is provided with a cusp structure 2, such as Figure 6 shown.

[0050] The occlusal repositioning device 1 on both sides is respectively fixed in the posterior teeth of the mandible, and then the upper and lower full-mouth models are taken, and the plaster model is cast and scanned. The obtained STL file is transferred to the invisible orthodontic design software for multi-step invisible orthodontic design , and finally form the STL de...

Embodiment 2

[0064] Example 2: Invisible correction of 3 types of malocclusion

[0065] First prepare the occlusal repositioning device 1. The occlusal repositioning device 1 is a bilateral resin crown with the correct tooth shape. The length of the occlusal repositioning device 1 on both sides is the sum of the correct teeth of 3 or 4 posterior teeth. The height of the repositioning device 1 is different depending on the vertical distance obtained in the posterior teeth after the mandible retreats to the upper and lower anterior teeth to open the locking knot. The lower part of the occlusal repositioning device 1 is provided with a cusp structure 2, such as Figure 13 shown.

[0066] The occlusal repositioning device 1 on both sides is respectively fixed on the bilateral maxillary posterior teeth, and then the full-mouth model of the upper and lower jaw is taken, and the plaster model is cast and scanned. The obtained STL file is transferred to the invisible orthodontic design software fo...

Abstract

The invention discloses an invisible correction method for treating class 2 and class 3 malocclusion by using an occlusion repositioning device, which comprises the following steps: respectively fixing the occlusion repositioning device on the mandibular or maxillary posterior tooth area on both sides, taking a maxillary and mandibular full-mouth model, filling a plaster model, scanning, transmitting an obtained STL file to invisible correction design software, performing multi-step invisible correction design, finally forming an STL design file, outputting the STL design file to a 3D printer to print a female mold, and pressing a transparent high polymer material on the female mold to form the bracket-free invisible corrector. The design process of the invention comprises the following steps: firstly, fixing an occlusion repositioning device to a back tooth area, connecting the back tooth area as a whole, not designing movement, only correcting an anterior tooth area, correcting the back tooth area, and finally finely adjusting the positions of upper and lower jaw teeth, thereby finishing orthodontic treatment of class 2 and class 3 malocclusion.

Description

technical field [0001] The invention relates to a correction method for malocclusion, in particular to an invisible correction method for treating type 2 and type 3 malocclusion by using an occlusal repositioning device. Background technique [0002] The masticatory organ is an integral part of the human body and consists of the neuromuscular system, the temporomandibular joint, and the occlusal structure, and it is evident that this organ performs different functions such as chewing, speech, breathing, swallowing, posture, aesthetics, and pressure-controlled molars Symptoms and clenching teeth. Considering that the oral and jaw system will be in a dynamic situation, if humans want to obtain a stable occlusal relationship, the following four conditions need to be met: 1. Canine control; 2. Sufficient vertical distance at the rear; 3. Gentle occlusal plane or Occlusal curve; 4. Stable cusp-fossa occlusal relationship. [0003] However, the occlusal characteristics of type 2...
