Embodiment Construction

[0034] In order to solve the shortcomings of the lack of elasticity and rapid attenuation of the transparent plastic used in traditional invisible aligners without brackets, the present invention uses a TiNi shape memory alloy with good superelasticity as the base 3 of the aligner. The shape memory alloy filament is braided, and then a layer of dentin-colored and gum-colored polymer soft lining material 4 is coated on the corresponding part of the outer surface of the base to achieve the purpose of invisibility.

[0035] In order to make the substrate 3 woven with shape memory alloy filaments have better clinical operability, it can be subjected to specific memory performance heat treatment, so that it has a good shape memory effect; ; the best is 24 degrees) and below it has good flexibility, which is convenient for doctors and patients to take off and wear; the base has good superelasticity at oral temperature (32-37 degrees), which can give full play to the long-lasting and ...

Abstract

The invention discloses a memory alloy non-bracket invisible appliance and a manufacturing method thereof. The memory alloy non-bracket invisible appliance is composed of a base and a silicone rubber covering membrane, wherein the base is made of shape memory alloy filaments, and the silicone rubber covering membrane is coated on the surface of the base and displays dental primary color and gingiva color; the filaments are prepared from TiNi alloys good in shape memory effect, are good in flexibility at room temperature, and good in super elasticity at the oral temperature (32-37 DEG C). The manufacturing method of the appliance includes the steps of firstly obtaining a required original dentition model, processing an entity dentition model, conducting compression molding on a piece of rectangular dense mesh woven by the shape memory alloy filaments by using the entity dentition model to form an initial state base, and conducting heating and sizing; adjusting the phase-transition temperature, covering the base with the silicone rubber covering membrane, according to the complete denture manufacturing process, finishing the membrane to form a tooth-shaped part and a gingiva-shaped part, removing unwanted parts, dyeing the tooth-shaped part into dental primary color and dyeing the gingiva-shaped part into gingiva color. The memory alloy non-bracket invisible appliance has the advantages of being simple, easy to use, and high in orthodontic treatment effect.

Description

technical field [0001] The invention belongs to the field of oral medicine orthodontics, and relates to a shape-memory alloy invisible aligner without brackets and a manufacturing method thereof. Background technique [0002] At present, in the field of orthodontics, the most commonly used is a fixed appliance composed of a dental arch wire and a bracket. Although this appliance can achieve a good orthodontic effect, its disadvantage is that it is neither beautiful nor comfortable. . In this context, bracketless clear aligners appeared. The existing invisible aligners without brackets use transparent elastic polymer materials to make a series of "braces" according to the expected arrangement of teeth. The patient's tooth alignment does not coincide and produces elastic deformation, thereby generating a certain amount of orthodontic force to push the teeth to move, achieving the therapeutic purpose of aligning the teeth. However, the elasticity of this transparent elastic ...
