Problems solved by technology

[0002] Mercury filling materials commonly used clinically as tooth defect restoration materials have problems of mercury pollution and toxicity, while commonly used composite resins cannot fully meet clinical needs due to their low strength and poor wear resistance.
Light-curing composite resin materials are widely used in filling and repairing tooth defects, and one of the necessary links is the removal of composite resin materials; clinically, sterilized filling instruments are often used to remove composite resin materials, but after composite resin materials are taken out, in It will cure slowly under light, and it is easy to be affected by external pollution and affect the performance of the material

Abstract

The invention relates to the technical field of medical supplies, in particular to a medical composite resin filling material. The medical composite resin filling material is prepared from, by mass, 10-20 parts of titanium powder, 3.6-8 parts of modified epoxide resin, 1.2-4.8 parts of titanate, 10-30 parts of EP glue, 10-20 parts of ceramic powder, 1.3-4 parts of quartz powder, 5-8 parts of glasspowder, 0.6-3 parts of adhesive and 0.2-0.6 part of curing initiator. According to the medical composite resin filling material, the ceramic powder, the quartz powder and the glass powder are added,so that the hardness and abrasion resistance of the filling material are greatly improved, and the service life is prolonged; meanwhile, the added raw material components are simple and easy to obtain, and have no toxic or side effects after being mixed for use, and the use safety is improved.
