Novel oral cavity orthodontic appliance

Abstract

The invention provides a novel oral cavity orthodontic appliance, wherein the appliance comprises a tooth socket body, and a orthodontic bench is arranged on the tooth socket. The orthodontic bench is arranged on a lingual side of incisors or a lingual sides of incisors and canine teeth of the tooth socket body, and comprises a contact surface and a holding surface, wherein one end of the contact surface is connected with the tooth socket body, the other end of the contact surface is connected with the holding surface, and the orthodontic bench is a plat bench or a sloping bench, when the orthodontic bench is a plat bench, the contact surface matches with a occlusalf surface of maxillary-mandibular teeth, when the orthodontic bench is a sloping bench, the contact surface is in parallel with a lingual side of the a occlusalf surface of maxillary-mandibular teeth, or the contact surface and the a occlusalf surface of maxillary-mandibular teeth form an included angle. According to the invention, an ordinary tooth socket and a flat bite plate or an inclined bite plate are integrated into one body to replace the clasp and the flat bite plate or the inclined bite plate with adjacent hook-type retention. The appliance provided in the invention enlarges indication scope of orthodontic invisable aligner technique, and the appliance can be applied in a bracket treatment system. The appliance has characteristics of comfortable wear, transparentness and beautiful look, and is made of an elastic polymer material. The appliance can give continuous elastic force to the tooth that needs to be intruded or led, so that the orthodontic effect is better.

Description

technical field [0001] The invention relates to a new type of appliance, in particular to a polymer material tooth cover with flat guide or oblique guide function, which belongs to the field of orthodontics. Background technique [0002] As an emerging orthodontic technology, invisible orthodontics without brackets are generally made of polymer materials. The orthodontic principle is to rely on the movement of polymer orthodontic braces to drive the patient's teeth to move accordingly to achieve the purpose of orthodontic treatment. At present, it is a big problem to depress the teeth by a large distance or guide the mandibular forward for deep overbite and deep coverage cases, and it is necessary to use flat or oblique guides together. At present, the production of flat guides or oblique guides is to obtain the retaining force through snap rings and adjacent hooks, etc., and to pave with self-curing resin. Since the self-curing resin needs to wrap and fix the snap rings, fl...

AI Technical Summary

Problems solved by technology

At present, the production of flat guides or oblique guides is to obtain the retaining force through snap rings and adjacent hooks, etc., and to pave with self-curing resin. Since the self-curing resin needs to wrap and fix the snap rings, flat guides or oblique guides are very difficult. Thick and hard, which greatly affects the comfort and curative effect of patients wearing
