Background

Dentures are artificial teeth that replace missing natural teeth. Also known as dentures. Partial or even complete loss of dentition can be caused by severe periodontal disease, dental caries, trauma, etc. After the teeth are lost, the functions of face appearance, pronunciation and chewing can be affected, the gastrointestinal burden is increased, if the teeth are not repaired in time, the adjacent teeth can be obliquely displaced, the jaw teeth can be extended, and the occlusion is disordered. The part of dentition is lost, and can be repaired by fixed denture or removable denture, and can be repaired by complete denture without teeth. The denture is often fixed by a base, and the shape of each tooth is not consistent, so that the base is not consistent, and the processing is difficult. And the base will loosen for a long time after being installed, so a denture base is urgently needed.

3D printing is one of the rapid prototyping technologies, which is a technology for constructing an object by using an adhesive material such as powdered metal or plastic and the like in a layer-by-layer printing manner on the basis of a digital model file. The method has the greatest characteristic of realizing personalized customization, namely, realizing the preparation of a complex-shaped structure according to the existing digital model (such as a three-dimensional scanner for realizing the rapid drawing of the shape of the teeth in the oral cavity).
