Laser-based method for non-deformation quantitatively adjusting of abrasion resistance of artificial dental crown occlusal surface

Abstract

The invention relates to a laser-based method for non-deformation quantitatively adjusting the abrasion resistance of an artificial dental crown occlusal surface, which comprises the following steps of: 1) preparing a plurality of micropores on the artificial dental crown occlusal surface by using laser; 2) coating liquid photosensitive resins on the surface of the micropores; 3) using an ultrasonic vibration head to abut against the area outside the micropores so as to completely fill all the micropore cavities with the liquid photosensitive resins; 4) irradiating a micropore area by using aphotosensitive curing lamp, and removing redundant impurities formed by the liquid photosensitive resins outside the micropores after the liquid photosensitive resins are preliminarily cured; 5) irradiating with the photosensitive curing lamp again until all the liquid photosensitive resins are completely cured; and 6) polishing the surface. According to the laser-based method for non-deformationquantitatively adjusting the abrasion resistance of the artificial dental crown occlusal surface, on the premise of not changing the existing occlusal contact of the artificial dental crown, the abrasion resistance of the occlusal surface of the dental crown can be quickly and quantitatively adjusted, so that the occlusal surface of the dental crown is adapted to the individual jaw teeth, and thebonding strength between the reinforcing material and the body material of the occlusal surface of the dental crown is greatly improved.

Description

technical field [0001] The invention relates to a method for quantitatively adjusting the wear resistance of the occlusal surface of a tooth crown, in particular to a quantitative adjustment method for the wear resistance of the occlusal surface of an artificial tooth crown based on laser without deformation. Background technique [0002] In the prior art, the method of adjusting the wear resistance of the occlusal surface of the crown needs to change the macroscopic three-dimensional shape of the existing occlusal surface of the crown and the occlusal contact relationship, which is often not suitable for the individual opposing teeth, and cannot quickly and quantitatively adjust the occlusal surface of the crown The surface wear resistance cannot solve the problem of the bonding strength between the strengthening material and the body material of the occlusal surface of the crown. Contents of the invention [0003] The purpose of the present invention is to provide a lase...
