Invisible appliance

Abstract

The invention provides an invisible appliance which comprises a single-jaw appliance and / or a double-jaw appliance. The single-jaw appliance comprises a maxillary tooth socket and a functional auxiliary part, and the double-jaw appliance comprises a double-jaw tooth socket and a functional auxiliary part. The double-jaw tooth socket comprises an upper jaw tooth socket, a lower jaw tooth socket anda connecting occlusal plate, the functional auxiliary part is selected from at least one of a palatal side plate, a lingual guide wing, an anterior tooth occlusion opening assembly and an extraoral traction assembly, and the anterior tooth occlusion opening assembly comprises a gingival margin bulge and a stress application pad; the extraoral traction assembly comprises an outer side tube and anextra-oral traction bow, and all parts are made of transparent or semi-transparent materials, so that the appliance is invisible. The appliance has a wide clinical application range, is suitable for malocclusion deformity of bone surface type II malocclusion and mild type III and can provide an efficient correction force system in the three-dimensional direction and especially greatly improve thecorrection efficiency in the vertical direction.

Description

technical field [0001] The invention belongs to the technical field of stomatology, and in particular relates to an invisible appliance. Background technique [0002] Malocclusion is the deformity of teeth and jaws caused by congenital genetic factors and / or acquired environmental factors during the growth and development of children, manifested as uneven teeth, maxillofacial deformities, etc., endangering the health and appearance of patients and function. Skeletal-facial class II and mild class III malocclusions are common clinical malocclusions, the main pathogenesis of which is maladjustment of the upper and lower jaws and / or the sagittal position of the dentition. Among them, the skeletal type II deformity is characterized by underdevelopment of the mandible, with or without overdevelopment of the maxilla; the mild type III malocclusion is characterized by a mild type III relationship between molars, often accompanied by anterior crossbite , with or without a slight m...

AI Technical Summary

Problems solved by technology

The prior art "mandibular guide CN201320028895.0" and "an invisible orthodontic device CN201720697007.2" overcome the weaknesses of traditional fixed orthodontics in terms of treatment duration and comfort, but there are still the following deficiencies: 1. The scope of clinical application is limited, It is only suitable for Angle's class II and bone-facial type II malocclusion, and cannot treat class III malocclusion; 2. It cannot control the growth of the maxilla, and it is accompanied by vertical and / or sagittal development of the maxilla In the case of excessive tendency, the lack of control of maxillary bone growth will significantly affect the curative effect and even lead to treatment failure; 3. The efficiency of depressing the anterior teeth to open the occlusion is low, and the treatment cycle is longer for cases with deep overbite; 4. Nighttime The efficiency of leading the mandible is low. The patient's perioral muscles relax during sleep at night, causing the upper and lower jaws to disengage. At this time, even if they wear an orthotic, they cannot function; and growth hormone is strongly secreted during sleep, which is to guide the growth and development of the jaw. prime time

These deficiencies limit the scope of clinical application and correction efficiency of existing invisible orthodontic devices
