Complete denture is a kind of restoration for patients with missing teeth, and its restoration materials include the following three aspects: 1, the base part: the general material is pressed methacrylic acid; 2, the base within the reinforcement part: this part of the commonly used materials, including cobalt chrome material or pure titanium material, cobalt chrome material is relatively softer and heavier, so it is not the preferred choice. It is generally recommended to choose pure titanium material, pure titanium material has higher strength, can be made relatively thin and lighter than cobalt chrome, so it is more comfortable to wear; 3, artificial teeth part: including resin teeth and steel teeth, resin teeth are relatively low wear-resistant, not wear-resistant, and steel teeth are relatively more wear-resistant.
