Embodiment 1

[0024] Choose CaF 2 As the coating material, a magnetron sputtering method is used. CaF 2 The powder was ball milled in a ball mill with a speed of 300 rpm for 24 hours, pressed into a Φ60*5 disc, sintered at a high temperature of 1250°C to make a target, and then sputtered on the surface of the orthodontic bracket by radio frequency magnetron sputtering. Sputtering conditions The frequency is 13.56MHz, the sputtering power is 250W, the working argon pressure is 1.5Pa, the target base distance is 65mm, and the sputtering is 3 hours, that is, the CaF-containing 2 slow-release coating.

Embodiment 2

[0026] Choose MgF 2 As a coating material, a sol-gel method is used. MgF 2 Make a sol, immerse the orthodontic bracket in the sol, pull it at a speed of 0.1mm / min, then dry it at 100°C for 1 hour, and heat it at 650°C for 3 hours to get the MgF-containing 2 slow-release coating.

Embodiment 3

[0028] The fluorine-containing hydroxyapatite is selected as the coating material, and the sol-gel method is adopted. First, fluorine-containing hydroxyapatite is made into a sol, and the orthodontic bracket is immersed in the sol, pulled at a speed of 0.5mm / min, then dried at 200°C for 2 hours, and heat-treated at 300°C for 1 hour to obtain fluorine-containing hydroxyapatite Apatite slow-release coating.

Abstract

The method of painting flourous delayed releasing matter onto denture to prevent demineralization of enamel is to paint flourous delayed releasing coating to the surface of the denture through magnetically controlled sputtering process or sol-gel process. The present invention completes functional treatment of denture and has easy operation and obvious effect of preventing demineralization of enamel.

Description

technical field [0001] The invention belongs to the technical field of oral orthodontic treatment, and in particular relates to a method for preventing tooth enamel demineralization in dental orthodontic treatment. Background technique [0002] When performing fixed orthodontic treatment on teeth, due to the long-term use of appliances, as well as the use of brackets, steel wires, ligature wires and other orthodontic accessories, the teeth, especially the tooth surfaces around the brackets, are not easy to clean. Enamel leukoplakia, a manifestation of enamel demineralization caused by poor oral hygiene, is common among patients undergoing orthodontic treatment, and it intensifies as the course of treatment increases, and severe cases may develop into early enamel caries. According to foreign statistical data reports, the incidence rate of enamel leukoplakia in orthodontic patients is about 50-70%. [0003] In recent years, various methods have been adopted to prevent enamel...
