Abstract

The invention discloses a denture material composition. The denture material composition is prepared from, by weight, 75-100 parts of methyl methacrylate, 85-100 parts of thermosetting denture base acrylic resin powder, 0.05-0.1 part of polysulfone resin, 0.2-0.3 part of plasticizer, 1.5-3.5 parts of tooth-making pigment and 5-15 parts of zirconium oxide. The denture material composition has the advantages that the thermosetting denture base acrylic resin powder and zirconium oxide are added into the composition, residual acrylate monomers are fewer, polymers absorb less water and fewer plasticizer and the like dissolve; the tooth-making pigment is added to satisfy the requirements of patients on tooth color; parameters of the denture material composition are optimized; dentures prepared from the denture material composition are excellent in stimulation, highly transparent, attractive and elegant without color change, low in cost and high in adaptability.

Description

technical field [0001] The invention belongs to the field of medical materials, in particular to a composition of denture materials. Background technique [0002] Dentures are what people often call "false teeth". Just like "prosthetic legs" and "prosthetic limbs" are called "prosthetic limbs", "dentures" mean teeth that perform "duties" for human beings. In medicine, it is a general term for restorations made after partial or complete loss of upper and lower teeth. There are three types of dentures: removable, fixed, and implants. Fixed dentures (commonly known as "fixed dentures") cannot be taken and worn by patients themselves, while removable dentures (commonly known as "movable dentures") can be easily taken and worn by patients. Dental implants are a relatively new technology that has developed rapidly in recent years. The method is to implant implants in the alveolar bone. After the implants and the alveolar bone form osseointegration, the teeth are placed on the i...
