A tooth surface treatment method and device based on plasma technology

Abstract

The invention discloses a tooth surface treatment method and a tooth surface treatment device based on a plasma technique. The device comprises a gas storage container, a plasma generator, a power supply and a spray gun, wherein the gas storage container is used for containing a working gas; the plasma generator is used for receiving the working gas from the gas storage container and used for outputting plasma flow after the working gas is subjected to plasma treatment; the power supply is used for supplying power to the plasma generator; the spray gun is communicated with the plasma generator and is used for applying the plasma flow to the surface of a tooth. According to the tooth surface treatment method and the tooth surface treatment device based on the plasma technique, the low-temperature acid etching plasma flow is utilized, the security and the comfort are improved, secondary pollution of diffusate is avoided, the stain on the surface of the tooth can be removed, an etching effect is achieved, and thus the bonding strength of the tooth with a support groove or a mounting material is improved.

Description

technical field [0001] The invention relates to the technical field of tooth treatment, in particular to a method and a treatment device for treating tooth surfaces by using plasma. Background technique [0002] During the orthodontic process, the surface of the tooth needs to be treated to increase the bonding strength between the bracket and the tooth. In addition, in the cosmetic process of tooth veneer, it is sometimes necessary to etch the tooth surface to improve the bonding strength with the veneer material. [0003] At present, the method of tooth surface treatment in orthodontics or veneer cosmetic process mainly adopts acid etching technology. [0004] The traditional acid etching technology includes successively using acid etchant and adhesive for treatment. After acid etching, the surface of the enamel is washed with water under a certain pressure to wash away the residual acid treatment solution and the flowable calcium salt deposited on the surface of the enam...

AI Technical Summary

Problems solved by technology

Although the self-etching agent can reduce the steps of clinical treatment, it is essentially the same as the acid etching, except that the acid etching agent and the binder in the traditional acid etching are mixed together to make the steps of acid etching and primer coating combined. Two into one, it is still unavoidable to need high-pressure water washing and other steps after acid etching

[0010] Treating the tooth surface with the current acid etching technology for bonding cannot meet the requirements of simple operation, reduced enamel damage, and safety without using any chemicals
