Long-Term Survival and Peri-Implant Health of Titanium Implants with Zirconia Abutments: A Systematic Review and Meta-Analysis.

Implants with zirconia abutments may have an acceptable performance on peri-implant health compared with all-titanium implants; however, the implant survival rate of implants with zirconia abutments is slightly lower than all-titanium implants in the long-term follow-up. Additional studies are needed to explain this dichotomy.
