Enumerate different implant materials with their pros and cons

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.

Carbon based materials- Solid or porous vitreous carbon has been used.
