Embodiment Construction

[0033] The manufacturing method of oral appliance includes the following steps:

[0034] 1. Establish a database of three-dimensional brackets corresponding to brackets with connecting rods.

[0035] Reference figure 1 , Bracket 1, is a specific structure in the movable wing, suitable for fixing on the labial side of incisors and canines. A connecting rod 11 extends at one end of the base of the bracket 1, and the end of the connecting rod forms a bending hook 111 structure , It can resist on the occlusal surface during assembly, provide a mating reference, and can be reliably embedded in the connecting plate 3, and can withstand sufficient corrective force after the glue is cured. Furthermore, the connecting rod 11 has a plurality of notches 112 on the side of the bracket surface, and the specific height of each bracket 1 bonded to the tooth surface can be known during operation, so as to increase the accuracy of bonding.

[0036] Reference figure 2 , Bracket 2 is a specific struc...

Abstract

The invention relates to an oral cavity appliance manufacturing method. The oral cavity appliance manufacturing method comprises following steps: a bracket database is constructed; an oral cavity teeth three dimensional model is extracted; assembling of the oral cavity teeth three dimensional model with the bracket is carried out; a connecting plate model is constructed; a connecting plate is produced via three dimensional printing; the connecting plate is provided with the bracket, arch wires, and orthodontic force so as to obtain a customized appliance finished product. According to the manufacturing method, three dimensional virtual technology is adopted to complete design and manufacturing of the connecting plate, and the preparation process is simplified greatly.

Description

Technical field: [0001] The invention belongs to the field of orthodontics, and particularly relates to a method for manufacturing an oral appliance. Background technique: [0002] Traditional orthodontic treatment is to paste the brackets and molar tubes on the labial side (outer side) or the lingual side (inner side) of the teeth in the oral cavity, and then insert the orthodontic arch wire. After the arch wire is ligated, the teeth are corrected. force. The process of assembling and adding force of the above components is carried out directly in the patient population, and the operation time is long, which brings a lot of inconvenience to doctors and patients. And due to the influence of the visual field and the tight operation time, errors are very easy to produce, which affects the treatment course and curative effect. [0003] Application No. 201610048837.2 discloses an oral appliance and a manufacturing method thereof, including a plurality of brackets, arch wires and liga...
