Abstract:The results of study on titanium artificial implants of dental root which dated from 1989 have been introduced. It was confirmed through clinical application that titanium has a good biocompatibility with the bone tissues and therefore is a potential candidate for dental materials. The morphologies of the implants can be leafy, spiral and stepped, and can also be divided into the whole and the separable styles. It was pointed out that the composite titanium , artificial implants of dental root should be developed in future.
Key words: titanium artificial implant biocompatibility
