Q. Enumerate different implant materials?
Biomaterials fall into four categories: metal and metal alloys, ceramics (carbon included in this group) synthetic polymers, and natural materials.
Alloys and Metals
Alloys such as stainless steel, Cobalt-Chromium and metals such as Titanium (Cp Ti), Ti-6Al-4V, Ti-6Al-4V (ELI), Tantulum, the Co-Cr alloys e.g. Co-Cr- Mo or Co-Cr-W-Ni.
Ceramics
The principal ceramic materials used experimentally at present for implants are Ca3(PO4)2, MgAl2O4, Ca aluminates, Ca3(PO4)2 -bonded Al2O3 and glass ceramics.
Polymers: Examples of polymeric dental implant materials include polymethyl methacrylate (PMMA),silicone rubber, polyethylene, Poly-Lactic Acid, polysulfone and poly tetrafluoroehtylene. "Bioresorbable" polymers (Poly Lactic Acid) are used as temporary implant materials that induce healing and bony ingrowth.
