Abstract

The invention discloses a method for removing a falling orthodontic bracket baseplate binding agent by means of ultrashort pulse laser scanning. A device which is used in the method comprises an ultrashort pulse laser device with visible indicating light, a round polarizing mirror system, a galvanometer scanning system, an orthodontic bracket clamp, a realtime monitoring system with a filtering unit, and a control system unit. Scan removing of he binding agent left on an orthodontic bracket baseplate is completed by using the ultrashort pulse laser device under different process parameters through the galvanometer scanning system. Attractiveness of a ceramic bracket is not damaged by utilizing cold ablative removing, on a material, of ultrashort pulse laser, so that the method has extremely high clinic application value. The whole method is simple and convenient, no any extra process is not needed, time for removing a single binding agent left on the orthodontic bracket baseplate is about one minute at the soonest, and the method is safe, environment friendly and efficient. Due to an unstressed binding agent removing mode, completeness of a whole orthodontic bracket substrate and a baseplate fixing structure is guaranteed.

Description

technical field

[0001] The invention relates to a method for removing the binder of the base plate of the orthodontic bracket by means of ultrashort pulse laser scanning. Background technique

[0002] As a very efficient orthodontic technology, orthodontic bracket bonding technology can complete orthodontic treatment for various complex and diverse dental malocclusion situations, so it has a very wide range of applications in orthodontic treatment. As the core part of orthodontic bracket bonding technology, orthodontic brackets often fall off during orthodontic treatment, and there are many factors that affect their falloff, such as the difference in the degree of patient cooperation, oral cavity Differences in the environment will increase the probability of orthodontic brackets falling off. Studies have shown that the rate of orthodontic bracket loss during orthodontic treatment can be as high as 54.3% ("Discussion on the Causes of Orthodontic Bracket Loss". "Shanghai Sto...
