Explanation

Also known as thermosetting resin. It is a resin materials that needs to be heated and coagulated to make denture base. The curing reaction can only occur when the temperature is above 65 ° C. The heat-curing denture base polymer is generally composed of powder and liquid. The trade name of the powder is denture base polymer powder, the main component is polymethyl methacrylate bead polymer, and the trade name of the liquid is denture base water. It is composed of monomer materials suitable for powder. When using, the thermosetting denture base polymer powder and thermosetting denture support water shall be mixed in a certain proportion. polymerization and intermediation are completed by pressure heating treatment process. The principle of polymerization is heat initiated free radical polymerization. Thermosetting denture base resin has stable mechanical strength and appropriate flexural strength in oral cavity. Easy to polish. Stable color. The coefficient of thermal expansion is relatively high. There is a certain degree of shrinkage after polymerization. Soluble in organic solvents. It is a kind of denture base materials widely used in clinic.
