Abstract

The invention relates to an abrasion-resistant tooth restoration material. The abrasion-resistant tooth restoration material is prepared from the following components in parts by weight: 95 to 100 parts of polymethyl methacrylate, 1 to 3 parts of oxidized cubic zirconia powder, 1.5 to 4.5 parts of trace rare earth element, 0.2 to 2.5 parts of nanometer aluminum oxide, and 0.2 to 0.5 part of nanometer quartz powder. Compared with the frequently used material in the prior art, the prepared abrasion-resistant tooth restoration material has the advantages that the indexes of strength, aging resistance, luster, abrasion-resistant degree, plasticizing and the like are respectively improved, the material cost is low, and the economic and practical effects are realized.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a wear-resistant tooth restoration material. 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] The application of composite resin materials began in the 1970s, and they are very popular because of their beautiful appearance and simple operation. Th...
