Osseointegrated dental implants.

Endosseous implants of commercially pure titanium have been demonstrated to give success rates of more than 90 per cent over 10 years of follow-up. This high level of clinical function depends on an implant direct anchorage in bone without any interposed soft tissue layers and on a reaction-free soft tissue surrounding the abutments. Provided a correct protocol is followed, such osseointegrated dental implants may be looked upon as a routine procedure in the treatment of edentulousness.
