All the materials used in medicine are safe. The law requires them to have certificates, marks, permits, approval, etc., issued by various governmental and EC bodies for their use in each of the countries where they are sold. They must also have gone through research and development processes in which their safety and quality are tested.
Despite all this, some materials are better quality than others. Your doctor should advise you about everything available on the market and you have to choose the material you want. It should not be the doctor who tries to convince you to have a particular kind of implant as though he or she is getting commission for selling them. The doctor’s role here is informative and of course they want to treat you with the best materials available, but he or she should never become a kind of pharmaceutical mercenary.
