Description

Tooth appliance

Technical Field

The utility model belongs to the technical field of orthodontic appliances, concretely relates to tooth unscrambler.

Background

In the present society with abundant substances, people pay more and more attention to the appearance of the people, the appearance image formed by the color and the shape of teeth becomes an important index for evaluating the personal appearance, the malocclusion deformity not only affects the teeth, but also affects the bone structure of the face, and finally affects the beauty of the face of the patient, so that the patient loses confidence on the appearance of the patient in daily life and becomes self-closed and unwilling to communicate with the people. Deformities of teeth have a great influence not only on the appearance of an individual but also on the physical health of the individual. The malformation of teeth can not normally chew food, resulting in dyspepsia, and the malformation of teeth can not clean food residue during tooth brushing, resulting in oral diseases. At present, the most common tooth socket is a steel wire tooth socket which is manufactured by a high-quality stainless steel wire, the cross section of the steel wire tooth socket is in a diamond shape, and the steel wire tooth socket is mechanically rolled into a spring-shaped thread. The diameter of the steel wire tooth socket is larger than that of the screw hole, when the steel wire tooth socket is installed, the steel wire tooth socket is compressed and tightened, the steel wire tooth socket rebounds to the original shape after installation is completed, and the steel wire tooth socket is permanently fixed in the screw hole. The bracket-free invisible braces which appear in the last 40 th century are novel malocclusion correcting braces, a series of movable correcting devices made of transparent materials are utilized to move teeth in a small range to correct malocclusion, and the bracket-free invisible braces have the advantages of attractiveness, convenience, predictable curative effect and the like, but have the defects of complex treatment process (the braces in one stage need to be replaced in two weeks), long period and the like.
