Bracket-free invisible orthodontic appliance produced based on tooth multi-position overlapping model and manufacturing method of bracket-free invisible orthodontic appliance

Abstract

The invention provides a bracket-free invisible orthodontic appliance produced based on a tooth multi-position overlapping model and a manufacturing method of the bracket-free invisible orthodontic appliance, and belongs to the field of invisible orthodontic appliances in an orthodontic technology. The orthodontic appliance comprises a dental cast and a tooth socket which covers the surface of the dental cast and is matched with the dental cast. After a digital tooth jaw model of a patient is obtained, one or more teeth are allowed to overlap in a plurality of design positions; an overlapping body is obtained through model Boolean operation; and the tooth socket is directly printed on the overlapping body tooth model or is obtained through indirect hot-pressing mold forming. Compared with a traditional invisible orthodontic appliance, the invisible orthodontic appliance of the invention has the following advantages that: the tooth socket has certain gaps on certain tooth surfaces, buccal lingual surfaces or mesiodistal middle surfaces, the tooth socket has more changeable shapes, and navigation of tooth movement or effective anchorage management by adjusting the orthodontic force is facilitated, so that the orthodontic efficiency of the invisible tooth socket is improved; and tooth eruption can be guided, the inter-jaw relationship is adjusted through locking of the teeth, and a certain growth improvement effect is achieved.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to a bracketless invisible appliance and a manufacturing method thereof, which are mainly used in orthodontic treatment to optimize the stress performance of the appliance, to adjust the magnitude of the orthodontic force at different parts, and to Teeth move for navigation. Background technique [0002] Bracket-free clear aligners are favored by patients because of their aesthetics, comfort, and ease of oral hygiene maintenance. More and more patients choose unbracket-free clear aligners to replace traditional fixed aligners for orthodontic treatment. Bracketless invisible aligners are a series of invisible braces obtained by scanning the patient's dentition to generate a digital dentition model, computer-aided design of the tooth movement sequence, 3D printing the dentition model of each step of the movement, and finally pressing the film to form a series of invisible braces....

AI Technical Summary

Problems solved by technology

At present, the existing methods include intermaxillary apron traction, braces lateral wing protrusion, braces noodle Pads, braces combined with the Forsus mandibular leading device can be used to adjust the intermaxillary relationship, but these methods rely on the patient's cooperation, poor comfort, adverse effects of tooth tilting, and the adjusted intermaxillary relationship is unstable and easy to relapse.
