Abstract

The invention discloses a preparation method of composite resin for filling teeth. Graphene oxide modified acrylic monomer is used to prepare acrylic resin, using this resin as the main raw material, 600~1500 mesh quartz powder, 500~5000 mesh white corundum powder, 0.5mm chopped micro glass fiber, polymerization inhibitor, photoinitiator and defoaming agent, dental filling composite resin prepared by dispersion stirring, vacuum treatment, etc. The preparation method of the invention is simple, the equipment is simple, and it is easy to be popularized on a large scale. The prepared composite resin for filling teeth has good biocompatibility, is not prone to allergies, and has better adhesion, wear resistance, durability and anti-aging The service life can be extended by 5-10 years.

Description

technical field [0001] The invention belongs to the technical field of medical polymers, in particular to a preparation method of composite resin for filling teeth. Background technique [0002] The advent of dental filling composite resin is a breakthrough in the history of dental materials. The biggest feature of composite resin for dental fillings is beautiful color, coordinated with natural tooth color, good chemical stability, insoluble in saliva, and various varieties. There are composite resins for filling anterior teeth, composite resins for posterior teeth, and composite resins for both anterior and posterior teeth. . The restored teeth can be completely confused with the real ones, and it is difficult for a professional dentist to determine the authenticity without careful identification. As soon as it was born, it was accepted by dentists and patients. [0003] However, composite resins for dental fillings also have some problems, such as susceptibility to alle...
