An invisible metal orthodontic bracket

Abstract

The invention relates to an invisible metal orthodontic bracket. Existing orthodontic brackets are extremely conspicuous and cannot achieve an invisible effect so as to affect use of users. The invisible metal orthodontic bracket is characterized in that a coating similar to the teeth in color is coated on the outer surface of the orthodontic bracket and is made of fluoride-free organic materials, the coating only covers the surface and the upper bottom surface of a base plate, and the lower bottom surface adhered with the teeth does not need to be coated. The invisible metal orthodontic bracket substitutes for orthodontic brackets made of stainless steel, ceramic and plastics on the current market, so that the orthodontic bracket retains the strength and toughness of the metal orthodontic bracket and has an invisible effect so as not to be perceived easily. Besides, the invisible metal orthodontic bracket has high smoothness, low friction enables a patient to feel more comfortable during orthodontic treatment, and the orthodontic treatment time can be shortened for the patient. The invisible metal orthodontic bracket is simple in coating process, convenient to operate and easy for industrial popularization.

Description

technical field [0001] The invention belongs to the field of oral orthodontic materials, in particular to an invisible metal orthodontic bracket. Background technique [0002] The orthodontic bracket is an important part of the fixed appliance, and the force is transmitted to the orthodontic bracket through the arch wire to make the teeth move according to the clinically designed plan. Clinically, brackets are required to have good mechanical properties, low friction, qualified biological properties, comfortable and beautiful to wear. The existing orthodontic brackets are divided into three types: stainless steel, ceramics (polycrystalline, single crystal), and plastic. Although the mechanical properties and other indicators of stainless steel brackets are very good, this kind of brackets are very conspicuous, and some adults are not easy to accept this easily noticeable metallic color; ceramic (polycrystalline) can achieve a certain invisible effect , but this kind of bra...

AI Technical Summary

Problems solved by technology

Coatings are divided into inorganic coatings and organic coatings. Inorganic coatings have high hardness but rough surfaces, high friction, and weak bonding, which cannot meet the requirements of the bracket. Organic coatings have low friction and high smoothness. Rich in color and beautiful to wear

However, most of the existing organic coatings are fluorine-containing resins, because of their advantages such as temperature resistance, corrosion resistance, low friction, and easy processing, but the raw materials for the production of fluorine resins may cause cancer. In the production process, it will cause serious pollution. If the separation of raw materials is not complete, there will be a great risk when it is applied to medical devices.
