Clinical performance of one ‐piece zirconia dental implants: A systematic review

AbstractThe aim of the present review was to evaluate the clinical and radiographic performance of one ‐piece zirconia implants (O‐PZI). This review followed the PRISMA (Preferred Reporting Items for Systematic Review and Meta‐Analysis) guidelines that addressed the following focused question: What is the overall clinical and radiographic performance of O‐PZI? The MEDLINE, EMBASE, Cochrane Ce ntral Register of Controlled Trials, and Cochrane Oral Health Group Trials Register databases were searched. Six clinical studies were included. For studies evaluating O‐PZI compared with one‐piece titanium implants, zirconia implants showed higher crestal bone loss (CBL) in both the studies. Ho wever, one study demonstrated a high failure rate compared to titanium dental implants, while one study demonstrated comparable survival rates between zirconia and titanium dental implants. For studies evaluating O‐PZI for the restoration of single crown and fixed dental prostheses, O‐PZI showed comparable bone loss and survival rates for single crowns and fixed dental prostheses. Two studies were included that compared O‐PZI with two‐piece zirconia (T‐PZI). One study showed a higher CBL and low survival rate for O‐PZI compared to T‐PZI, whereas the other study demonstrated compa rable CBL and survival rates between O‐PZI and T‐PZI. It is still debatable whether O‐PZI demonstrate better clinical performance when compared with titanium implants or two‐piece design...
