But as today there are really only three basic biomaterials that have proven consistently effective and easily manufactured with a relatively low incidence of complications in human facial implantation use. These biomaterials are silicone, polyethylene (Medpor) and polytetrafluoroethylene. (PTFE) None of them are perfect and each have their own distinct advantages and disadvantages. By far silicone is the most widely used facial implant material around the world followed by Medpor at a very distant second.

The least well known facial biomaterial is that of PTFE even though it has been used in the face for over thirty years in various forms, most commonly for soft tissue augmentation. PTFE implants are made of carbon and fluorine molecular chains (CF2-CF2) that create a synthetic polymer that is compl...
