Abstract:
The aim of this study was to evaluate the 5 year success rate of ZrO2 implants with three different kinds of surfaces. One-piece zirconia dental implants (CeraRoot, Barcelona, Spain) with 1 of 3 different roughened surfaces were designed and manufactured for this study: Coated (C), Non-Coated (NC) and the ICE (acid-etched). Five different implant designs were manufactured. Standard or flapless surgical procedures were used for implant placement. Simultaneous bone augmentation or sinus elevation was performed in the cases where bone height or width was insufficient. Definitive all-ceramic restorations were placed 4 months after implant placement (8 months or more for implants where bone augmentation or sinus elevation was performed). The implants were followed up to 5 years (mean=3,40±0,21). Results: A total of 831 implants were placed in 378 patients with a mean age of 48 years. The overall implant success rate after 5 year follow-up was 95% (92,77 % for the N-C; 93,57% for the C; and 97,60% for the ICE). The success rate of the ICE surface group was significantly better than the other two. From this mid-term investigation, it can be concluded that zirconia dental implants with roughened surfaces might be a viable alternative for tooth replacement. Further follow-up is needed to evaluate the long-term success rates of the implant surfaces studied.
