Bracket-free invisible orthodontic device capable of guiding lower jaw to move by traction and manufacture method thereof

Abstract

A bracket-free invisible orthodontic device capable of guiding the lower jaw to move by traction and a manufacture method thereof are provided. The bracket-free invisible orthodontic device comprises an upper jaw brace, a lower jaw brace and a tractive member; the front tooth region of the upper jaw brace is provided with a hooking point; two cheek sides of the rear tooth region of the upper jaw brace are provided with upper protrusions; the upper protrusions are projected from the upper jaw brace to the cheeks; two cheek sides of the rear tooth region of the lower jaw brace are provided with lower protrusions; the lower protrusions are projected from the lower jaw brace to the cheeks; each lower protrusion is laterally provided with a lug; one end of the tractive member is hooked to the lugs; the other end of the tractive member is hooked to the hooking point of the upper jaw brace. The bracket-free invisible orthodontic device has the advantages that the braces made with transaprent membranes are attractive and well comfortable to wear; the upper jaw and the lower jaw are provided with their braces respectively, and the braces can provide biological forces to guide the lower jaw to move when the upper jaw and the lower jaw are occluded or separated; dentitions are organized at the premise of improving mandibular retrusion, and correction efficiency is high.

Description

technical field [0001] The invention relates to the field of orthodontics, in particular to a tractable invisible orthodontic appliance without brackets for guiding mandibular movement and a manufacturing method thereof. [0002] technical background [0003] The purpose of malocclusion correction is to achieve occlusal beauty and functional stability. The difference between juvenile malocclusion and adult malocclusion is that adolescents are undergoing development and growth. Choosing the most suitable orthodontic treatment position for juvenile maxillofacial structure makes orthodontic treatment The results are in harmony with the developmental growth of adolescents. [0004] For skeletal Class II malocclusion, the best period of correction is the early stage of rapid adolescent growth and / or the rapid growth period of adolescents. During this period, tooth extraction can be avoided, and the mandible can be pulled forward to the normal position through Class II elastic trac...

AI Technical Summary

Problems solved by technology

The Twinblock appliance has the advantages of shorter treatment time, relatively good comfort, and high patient cooperation, but it cannot align the teeth while correcting skeletal problems, and does not have the function of oral function training; the Frankel function adjuster can solve some problems. Early dental and maxillofacial deformities, but require complex craftsmanship, large volume, poor patient compliance, and unattractive metal materials; MA appliance is a non-bracket invisible appliance, invisible and beautiful, but when the patient’s upper and lower jaws are separated, The orthodontic appliance cannot protrude the mandible for correction; the SGTB orthodontic appliance has a jaw pad and needs to be worn by the patient when eating to maintain the protruding state of the mandible, resulting in poor comfort
