Personalized customized fixed-function appliance for mandibular protrusion

Abstract

The present invention provides a fixed-function appliance for customizing and guiding mandibular protraction, which includes an upper orthodontic assembly and a lower orthodontic assembly. The upper orthodontic assembly adopts an integrated upper orthodontic assembly. The left upper metal crown, the upper right metal crown on the right maxillary first molar, and the maxillary protrusion guiding device respectively installed on the buccal side of the left upper metal crown and the right upper metal crown; The metal crown, the lower right metal crown set on the right mandibular first molar, and the mandibular distance adjustment devices respectively set on the buccal sides of the metal crowns on both sides of the mandible. The overall structure of the appliance is stable, which can ensure an effective orthodontic effect, avoid the problem that parts fall off and separate and affect the orthodontic effect, and can precisely control the distance of mandibular protruding. At the same time, the appliance is small in size, simplified in structure, and the upper and lower jaw components are separated, which can reduce the patient's discomfort without affecting eating and chewing.

Description

technical field [0001] The invention relates to a fixed-function appliance that can be personalized and customized to guide mandibular protraction. Background technique [0002] Angle II 1 The main characteristics of patients with quasi-mandibular retrusion are that the mandible and lower dental arch are in the distal position, the molars are in a distal relationship, and the maxillary anterior teeth are labially oriented, and ANB>5°, such as figure 1 . Clinically, currently for Angle II 1 Patients with mandibular retrusion mainly use two types of fixed function appliances: [0003] The first type is the Herbst appliance. The Herbst appliance commonly used in clinical practice can inhibit the growth of the maxilla to a certain extent, which is unfavorable for Angle II patients with normal maxilla and retracted mandible. The molars and mandibular incisors are vertically depressed to a certain extent, resulting in a clockwise rotation of the occlusal plane, that is, t...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a fixed-function appliance that can be personalized and customized to guide mandibular protraction to solve the existing MARA appliance (i.e. mandibular leading appliance) with many parts, which are retained by elastic rubber rings, rubber The ribs are easy to fall off, easy to fall off, the structure is unstable, it is difficult to guarantee the correction effect, and the production process is complicated
