Classification of Biomaterials5.1 The pr

40、operties of a biomaterial are a function of whichtype of material they are made from. All materials can beclassified according to their atomic content and bonding aseither a ceramic, polymer, metal, or composite. Ceramicsconsist of ionically or covalently bonded metallic and non-metallic elements su

41、ch as calcium phosphate or aluminumphosphate and include minerals and glasses, sintered or unsin-tered. Polymers consist of a repeating backbone structure.Metals are made of metallic elements bonded together bymetallic bonds. Composites are blends of any of the three maintypes of materials. Even mat

42、erials derived from natural sourcessuch as anorganic bone or chitosan fall into one of these basictypes; anorganic bone is a ceramic and chitosan is a polymer.5.2 To use this guide, first classify the material into one ofthe types above.
