In recent years, the field of stomatology in our country has been booming, especially the clinical application of various new oral materials has been advancing at an unprecedented pace, which has greatly promoted the development of stomatology. How to select and use various restorative materials well is the guarantee of successful oral restoration.

Whether it is the application of titanium materials and titanium scaffold dentures, or the application from polymethyl methacrylate to composite resin, as well as the application from porcelain-fused-to-metal materials to castable ceramic materials and cut-able ceramics, the development of oral application materials science has played an irreplaceable role in improving the quality of oral restoration.

The development of nanoceramics, especially the application of nanomaterials in oral restoration, will greatly improve the biocompatibility, strength, toughness, weight and corrosion resistance of materials, and is expected to become ideal materials for oral restoration.

The biological properties of the oxide film on the surface of metallic materials can enhance the biocompatibility of the materials, enabling the acquisition of more biological repair materials and making bionic repair possible.
