Self-locking orthodontic bracket for tooth orthodontics

Abstract

The invention relates to a dentognathic malformation correction technology, and aims at providing a self-locking orthodontic bracket for tooth orthodontics. The product comprises a basal plate shaped as a cambered surface and a bracket body connected with the basal plate. The bracket body is divided into two parts by a penetrating main arch wire groove, the two parts are respectively provided with a cover sheet inserting port and a cover sheet locking port. A cover sheet is shaped like a Chinese character shan (as shown in figure 5) and is made of nickel-titanium material or stainless steel, protruding portions of the cover sheet are shaped as three parallel rectangles, the inner side of the end of each of the protruding portions at two sides is oppositely provided with a horned part, and the protruding portion in the middle has a downward recess shape. The self-locking orthodontic bracket can enable a clinic oral cavity orthodontic doctor to place a dental arch wire into the arch wire groove of the bracket, can achieve active ligation and passive ligation without a ligation wire, can enable teeth to be rapidly moved during a treatment process, and also can accurately control torsional teeth. The self-locking orthodontic bracket can effectively shorten a clinic operation time of the orthodontic doctor, and simultaneously can shorten a treatment cycle of a patient.

Description

technical field [0001] The invention relates to correction technology of dento-jaw deformities, in particular to a self-locking orthodontic bracket used for tooth correction, which can realize active ligation and passive ligation of main arch wire in clinical practice. Background technique [0002] At present, the existing orthodontic brackets on the market at home and abroad can be divided into active ligation brackets from the clinical ligation method (active ligation type: the ligation wire is used to ligate the arch wire and the bracket, so that the dental arch wire and the bracket arch The wire slots are in close contact, and the existing common brackets are basically active ligation type) and passive ligation type brackets (passive ligation type: the dental arch wire does not need to be ligated with ligation wire, and the relationship between the dental arch wire and the bracket arch wire slot is basically Without restraint, self-ligating brackets basically belong to t...

AI Technical Summary

Problems solved by technology

Since the passive self-locking has almost no binding force on the dental arch wire, although the teeth can be moved quickly during the stage of using the thin arch wire to correct the teeth, the control force on the twisted teeth becomes weak because the control force generated by the thin arch wire is too weak. Poor, it becomes difficult to correct twisted teeth

[0003] China's invention patent application for "self-binding orthodontic brackets". Although the product has an active self-locking function and can use thick arch wires, the structure of the product is very complicated due to the use of hinge pins and latches, which is difficult for manufacturing and processing. bring high precision requirements
