Zirconia implants have become a very promising alternative to conventional titanium implants for oral rehabilitation with superior biological and esthetical properties. An electronic search through PubMed about zirconia dental implants has been performed in the English language. Zirconium dioxide implants demonstrate excellent biocompatibility, gingival adhesiveness and esthetic benefits. The evidence for one-piece ceramic implants has become strong enough that these implants have a similar range of indications as titanium implants and can be used in the same situations. However, lack of evidence for long-term success of two piece zirconia Implants above 5 years are considered to be a drawback.
