AI Technical Summary

Technical Problem

Existing muscle activators cannot fit snugly between the upper and lower braces, affecting the orthodontic effect, and are also bulky and uncomfortable.

Method used

The design incorporates a muscle activator that links the upper and lower teeth. Through the detachable connection between the upper and lower invisible braces and the setting of V-shaped bending connecting strips or clips, it achieves the alignment and correction of the upper and lower teeth. An angle-forming plate is used to reserve space for the growth of posterior molars, and the structure is optimized to facilitate the user's adaptation to the biting action.

Benefits of technology

It achieves close coordination between the upper and lower teeth, improves the orthodontic effect, reduces the feeling of foreign objects, and enhances comfort and convenience.

Abstract

The utility model relates to the technical field of dentistry. The utility model relates to a muscle agonist for linked correction of upper and lower teeth. The muscle agonist comprises an upper invisible tooth socket and a lower invisible tooth socket, wherein the upper invisible tooth socket is sleeved outside upper teeth; the lower invisible tooth socket is sleeved outside lower teeth; the incisor part of the lower invisible tooth socket is detachably connected with the incisor part of the upper invisible tooth socket; the occlusal surface at the molar position of the lower invisible tooth socket is connected or detachably connected with the occlusal surface at the molar position of the upper invisible tooth socket through a V-shaped bent connecting strip; an angle forming plate is clamped between the upper invisible tooth socket and the lower invisible tooth socket, and the angle forming plate is positioned on the occlusal surface of at least one of the upper invisible tooth socket and the lower invisible tooth socket. According to the utility model, by optimizing the structure of the muscle agonist, the upper invisible tooth socket can be conveniently matched with upper teeth, and after the upper invisible tooth socket is matched with lower teeth, the incisor part of the lower invisible tooth socket is detachably connected with the incisor part of the upper invisible tooth socket, so that the alignment of an upper jaw and a lower jaw is realized, and the correction of dentition deformity of relative protuberance of the upper jaw and retroduction of the lower jaw is realized.
