Abstract

The invention discloses a multicolor integrated dental repair material and a preparation method thereof and relates to the technical field of denture repair materials. The multicolor integrated dentalrepair material and the preparation method thereof can solve the problem that false teeth made of existing repair materials are different in color from real teeth and unattractive in appearance. Themulticolor integrated dental repair material is composed of raw materials including, by weight part, 60-70 parts of polymethyl methacrylate, 30-40 parts of methyl methacrylate, 0.03-0.06 part of 2, 6-di-tert-butyl-4-methylphenol, 0.02-0.04 part of N, N-dimethyl-p-toluidine, 0.02-0.04 part of glycol dimethacrylate and 0.2-0.6 part of color master batch. According to the preparation method of the multicolor integrated dental repair material, through interaction of catalysts, cross-linking agent and polymerization inhibitor, curing speed can be controlled; through a casting manner, the multilayercolor-gradient dental repair material can be prepared. The multicolor integrated dental repair material is high in simulation, attractive in appearance, wide in applicability, capable of meeting people's demand on color-gradient dentures and improving the denture processing efficiency, high in interfacial strength, less prone to separation when under cutting force during processing and good in impact resistance.

Description

technical field [0001] The invention relates to the technical field of denture restoration materials, more specifically, it relates to a multi-color integrated dental restoration material and a preparation method thereof. Background technique [0002] Dental restoration materials are biomaterials used in the human body, which not only require implantation in the human oral cavity, but also require long-term stable function in the specific environment of the oral cavity. Therefore, dental materials need to have good biocompatibility, be able to resist the corrosion of oral saliva, and have good mechanical properties, including strength, hardness, toughness, and wear resistance. In addition, with the application of CAD / CAM technology, a method of replacing traditional wax casting with CNC machine tool machining has been formed, which requires dental restoration materials to be able to be machined. [0003] In the Chinese invention patent with the publication number CN10682300...
