Description

Orthodontic auxiliary device for anterior teeth and orthodontic device

Technical Field

The utility model belongs to the field of medical equipment, a tooth plastic device is related to, concretely relates to tooth correction auxiliary device and tooth orthotic devices for anterior teeth.

Background

The transparent appliance is a series of transparent appliances manufactured by the steps of scanning the mouth, taking a model, scanning a plaster model or an impression to obtain a digital model of dentition of a patient, dividing the digital dentition model into single movable digital dentition units, rearranging the dentition units to obtain needed corrected dentition, obtaining a series of intermediate digital dentition models by a step-by-step method, printing the intermediate models in a 3D way, and manufacturing a series of transparent appliances by using a thermoplastic molding film-pressing material. The patient corrects the dentition misalignment by wearing these series of transparent appliances.

Transparent appliances present many uncertainties and inaccessible ways of movement for tooth movement. For the transparent appliance, the effect of aligning the dentition is obvious when the crowded cases are corrected, but the whole treatment effect is not as good as that of the fixed appliance, and the occlusion contact is mainly realized. The transparent appliance design is based on a digitized model, and the upper and lower jaw bite positions of the digitized model are based on the initial neutral position of the patient. When the upper dentition and the lower dentition are arranged, the occlusion of the upper dentition, the lower dentition and the dentition can be changed, but the occlusion relation after the tooth arrangement is designed is artificially determined after digital teeth are moved, and the actual occlusion position of a patient cannot be expressed. Meanwhile, the digital model based on which the existing transparent appliance is designed lacks the relation of relative movement positions of the lower jaw when the mouth is opened or closed. Therefore, the transparent appliance is often not good in the occlusion relationship of the posterior teeth after being corrected, and even opens and closes. The transparent appliance corrects the irregular dentition, the upper part and the lower part of the appliance are separated, and the upper dentition and the lower dentition are actually in occlusion relation. The position of the anterior teeth often in turn affects the initial bite position of the patient. In the process of correction, the teeth are often difficult to bite into a stable position along with the change of the positions of the teeth, and finally, the occlusion effect is poor.
