Each participant received four implants in the maxilla (mid\u2010palatal and three anterior crestal implants) and three implants in the mandible (mid\u2010symphyseal and two bilateral distal implants). Conventional loading protocol was followed. Marginal bone remodeling and clinical success of implants were evaluated. The data were statistically analyzed, and risk predictors for implant failures were evaluated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There was no significant difference in the survival rate between the two groups. In the mandible, the survival rate of titanium implants was 95.8% vs. 90.9% for the zirconia implants. The corresponding values in the maxilla were 71.9% and 55%, respectively. Three implants in the zirconia group fractured. Statistically significant less marginal bone loss was observed around titanium implants (0.18\u00a0mm) compared with the zirconia group (0.42\u00a0mm). The prediction model revealed a higher risk for implant failures in the maxilla (<jats:italic>P\u00a0<\/jats:italic>&lt;<jats:italic>\u00a0<\/jats:italic>0.0001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The outcome of this study indicates caution before recommendation can be made for the use of single\u2010piece zirconia implants for overdenture support. Their use should be limited to cases with proven allergy to titanium. This is mainly due to the increased bone loss and higher fracture rate observed for zirconia implants. Future biomaterial research should focus on producing surface characteristics on zirconia implants with outcomes similar to those established for the optimum osseointegration of titanium implants.<\/jats:p><\/jats:sec>","DOI":"10.1111\/clr.12272","type":"journal-article","created":{"date-parts":[[2013,10,12]],"date-time":"2013-10-12T02:32:57Z","timestamp":1381545177000},"page":"1366-1377","source":"Crossref","is-referenced-by-count":77,"title":["Ceramic implants (Y\u2010<scp>TZP<\/scp>): are they a viable alternative to titanium implants for the support of overdentures?
