At present, commonly used dental materials can be divided into three categories: metal, dental composite resin and ceramic materials. Each category includes many kinds of materials.

For example, nickel-chromium alloy, cobalt-chromium alloy, titanium alloy, pure titanium and gold alloy are commonly used as metal materials.

The chemical composition of composite resin is basically the same, which is based on diacrylate resin and added with different components. Different brands of composite resins have similar chemical composition.

Commonly used ceramic materials are feldspar ceramics, alumina ceramics and zirconia ceramics.
