What are the materials for fixed denture

1. Metal materials: high strength, suitable for fixed bridges on more hidden posterior teeth.
2. Porcelain material: combines the mechanical strength of metal and the aesthetic properties of porcelain, but there is a risk of chipping in the long term.
3. All-ceramic materials: hard, chemically stable, biocompatible, aesthetic and comfortable.
4. Resin material: low hardness, easy to wear, chemically unstable, generally suitable for temporary fixed bridges.
