Orthodontic correction auxiliary device used for anterior teeth, and orthodontic correction device

Abstract

The invention discloses an orthodontic correction auxiliary device used for anterior teeth, and an orthodontic correction device. The orthodontic correction auxiliary device is fixed on an orthodonticcorrection device. The orthodontic correction device comprises an upper anterior tooth dental crown cover and a lower anterior tooth dental crown cover. The auxiliary device comprises upper jaw anterior tooth occlusion positioners and lower jaw anterior tooth occlusion positioners, wherein the upper jaw anterior tooth occlusion positioners and lower jaw anterior tooth occlusion positioners are distributed and fixed on the outer walls of the upper anterior tooth dental crown cover and the lower anterior tooth dental crown cover; the upper jaw anterior tooth occlusion positioners are fixed on the outer wall of the palate side of the upper anterior tooth dental crown cover; and under an occlusion state, the center of the contact surface of each upper jaw anterior tooth occlusion positioner and each lower anterior tooth dental crown cover is positioned on a lower anterior tooth occlusion vertical line. Through the transparent correction device provided with the occlusion positioners, an occlusion relationship in a correction process and after correction is improved, a stable occlusion function is obtained for a patient, and the defects in clinical application that due to an occlusionproblem, restarting needs to be carried out, the transparent correction device needs to be manufactured again, or an occlusion problem needs to be corrected through a method that a fixed correction device needs to be clinically utilized can be eliminated.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a tooth shaping device, in particular to a tooth correction auxiliary device and a tooth correction device for anterior teeth. Background technique [0002] The transparent appliance is to obtain the digital model of the patient's dentition by scanning the plaster model or impression after taking the impression, dividing the digital dentition model into a single movable digital dental unit, and rearranging these dental units to obtain the required orthodontic dentition , through a step-by-step method to obtain a series of intermediate digital dentition models, 3D print these intermediate models, and use thermoplastic molding materials to produce a series of transparent aligners. Patients correct their misaligned teeth by wearing these series of clear aligners. [0003] There are many uncertain and difficult-to-achieve movement modes for tooth movement with transparent aligners. F...

Problems solved by technology

During the orthodontic process, as the position of the teeth changes, it is often difficult to occlude into a stable position, which eventually leads to poor occlusal effect
