Zirconia materials are widely used in dental restorations. At present, the main dental restoration methods can be divided into the following three categories according to the degree of tooth damage from small to large:
1. Inlay repair, suitable for partially damaged teeth, filling with inlays to protect and repair teeth. Commonly used inlay repair materials are mainly resin, metal and ceramics;
2. Crown repair, suitable for the case of large tooth defect or disease, but the root of the tooth is still there. Commonly used crown materials are alloys, porcelain and all-ceramic;
3. Denture restoration, suitable for missing teeth or extracted teeth.
From the perspective of the industrial chain, the upstream of zirconia dental materials is the supplier of zirconia raw materials, providing composite nano-zirconia ceramic powder. Midstream is a dental material manufacturer that manufactures zirconia ceramic blocks for teeth. In the downstream, due to the particularity of the industry, dental laboratories, dental hospitals or clinics are required to process the materials according to the conditions of different patients, and form the final finished denture, which is then assembled into the patient's mouth.
