The role of plastic bracket sanding in the manufacture of complete denture

Frosting in plastic brackets is helpful to the stability of complete denture. In the process of making complete denture, the polished surface is formed by grinding the rubber bracket in the automobile bracket. Polished surface is the contact surface between denture and soft tissues and muscles of lips, cheeks and tongue. The shape of the polished surface consists of different inclined planes. When the inclination of polishing surface, the width of denture edge and the position of buccal tongue of artificial teeth are normal, tongue and buccal tissue can help denture maintain and resist lateral pressure.
