Technical Field
The invention belongs to the field of appliances for tooth correction, and particularly relates to a novel invisible orthodontic tooth socket and a manufacturing method thereof.
Background
There are two types of known dental appliances, one being a fixed appliance and the other being a bracket-less concealed appliance. Both appliances correct the teeth by means of a stepwise adjustment, but each has advantages and disadvantages. For users, the fixed appliance has good correction effect, but is not beautiful and not easy to clean. For a user, the bracket-free invisible appliance is attractive and easy to clean, but the bracket-free invisible appliance corrects teeth in a mode that the rigid structure drives the teeth to move, so that in the initial stage of correction, if the teeth of the user are not easy to move, the rigid structure of the invisible appliance cannot provide enough force to correct the teeth, and the teeth cannot be corrected; in addition, if the teeth of the user are too disordered, the invisible appliance cannot be fixed; thirdly, the price of the invisible aligner is higher than that of the dentition aligner; furthermore, because the upper row of teeth and the lower row of teeth of the user are straightened separately by the invisible appliance, the upper row of teeth often cannot be occluded with the lower row of teeth after the orthodontic treatment is completed and the invisible appliance is removed.

When the user has periodontal disease, the teeth can be corrected while protecting the damaged teeth. When a user has temporomandibular joint discomfort symptoms or a sensitive tendency, the teeth can be corrected while muscles are relaxed, mandibular joints are stabilized, occlusion wounds are reduced, and the course of correction treatment is shortened.
The invention also provides a preparation method of the tooth socket, and the tooth socket prepared by the method can effectively improve the condition that the upper row of teeth cannot be occluded with the lower row of teeth after the invisible orthodontic device is removed after the orthodontic operation is finished.
The technical scheme adopted by the invention is as follows: a preparation method of a novel invisible orthodontic tooth socket with stable lower jaw position and occlusion relation comprises the following specific steps: a. collecting three-dimensional data and data of the skull, teeth and bite of the user; designing tooth movement steps of the upper dentition and the lower dentition by planning data and data of the skull, the teeth and the occlusion; according to the tooth moving step, an elastic invisible tooth socket with elastic upper and lower dentitions is made of elastic materials for later use;
b. carrying out occlusion of a molar area of an occlusal surface and incisional guidance design of anterior teeth according to data and data of upper and lower jaws and dentitions;
c. further manufacturing occlusion sleeves of upper and lower dentitions made of hard materials according to the tooth moving steps and the occlusal surface design for later use;
d. and d, sticking the elastic invisible tooth socket with the elastic upper and lower dentitions prepared in the step a on the inner wall of the occlusion socket prepared in the step c, thereby obtaining the novel invisible orthodontic tooth socket with stable lower jaw position and occlusion relation.
Preferably, in the step d of the method for preparing the novel invisible orthodontic braces with stable lower jaw position and occlusion relation, the elastic invisible braces of the upper dentition and the lower dentition are adhered to the inner wall of the occlusion braces by the plasma adhesion technology.
Preferably, the invention relates to a preparation method of a novel invisible orthodontic tooth socket with stable lower jaw position and occlusion relation, wherein the elastic material adopted by the elastic invisible tooth socket of the upper dentition and the lower dentition is ethylene or vinyl acetate copolymer.
Preferably, in the step b, the method adopted for occlusal surface molar area occlusion and anterior tooth incisional guidance design according to the data and the data of the upper jaw and the lower jaw and the dentition is obtained by reconstructing the CAD in Super Virtual software.
The novel invisible orthodontic tooth socket with the stable lower jaw position and occlusion relation, which is prepared by the method, comprises an upper elastic invisible tooth socket coated on an upper dentition and a lower elastic invisible tooth socket coated on a lower dentition; the upper occlusion sleeve and the lower occlusion sleeve are constructed according to the upper jaw, the lower jaw, the upper dentition and the lower dentition, and are made of hard materials; the upper elastic invisible tooth socket is stuck on the inner wall of the upper occlusion sleeve, and the lower elastic invisible tooth socket is stuck on the inner wall of the lower occlusion sleeve.
Preferably, the novel invisible orthodontic tooth socket with the stable lower jaw position and occlusion relation is manufactured by adopting a 3D printing technology.
The invention has the following beneficial effects:
the novel invisible orthodontic braces manufactured by the steps and the method have the personalized occlusion braces, so that the occlusion braces can stabilize temporomandibular joints, relax muscles and reduce occlusion wounds and periodontal tissue injuries. Simultaneously, this novel stealthy tooth cover of straightening elasticity about having elasticity in the tooth cover can cooperate user's interlock to and the mechanical properties of material itself, provide sufficient strength and correct upper and lower dentition simultaneously. In addition, the novel invisible orthodontic tooth socket has the advantages of attractive appearance, easiness in cleaning, difficulty in damaging the oral cavity of a user and the like. Furthermore, if the user has the tooth missing condition, other teeth can be corrected without being influenced by the tooth missing position. Finally, due to the action of the hard occlusion sleeve, the invisible orthodontic sleeve does not influence the occlusion of the upper and lower teeth in the using process; and after the correction is finished, the occlusion of each tooth of the upper and lower teeth is not influenced. Therefore, the soft-hard combined double-layer novel invisible tooth socket effectively overcomes the defects of the existing invisible tooth socket and can realize real effective correction.
