Objective This review aimed at evaluating the survival and technical complication rates of all‐ceramic implant‐supported single crowns ( SC ). Material and Methods Three electronic databases were searched for clinical studies conducted at ≥ 15 patients examining implant‐supported all‐ceramic SC s over ≥ 12 months. Survival rates of implants and restorations plus technical complication rates of SC s were calculated and tested for statistical correlation with confounding variables. Statistical analysis was performed using a negative binomial distribution model to calculate 5‐ and 10‐year survival and complication estimates. Results Forty‐one included studies reported on implant‐supported SC s made of veneered and monolithic high‐strength oxide ceramics, monolithic, and veneered glass‐based ceramics and of a monolithic resin‐nano‐ceramic ( RNC ). Survival estimates for SC s of 93% (95% CI : 86.6%–96.4%) after 5 years and 94.4% (95% CI : 91.1%–96.5%) after 10 years were calculated, corresponding values for implant survival were 95.3% (95% CI : 90.6%–97.7%) and 96.2% (95% CI : 95.1%–97.1%). Technical complication rates after 5/10 years were as follows: chipping 9.0% (95% CI : 5.4%–14.8%)/2.7% (95% CI : 2.1%–3.5%), framework fractures 1.9% (95% CI : 0.7%–4.9%)/1.2% (95% CI : 1%–1.5%), screw loosening 3.6% (95% CI : 1.6%–8.4%)/5.2% (95% CI : 3.6%–7.5%), and decementations with 1.1% (95% CI : 0.4%–2.8%) after 5 years. Some confounding variables influenced the above‐mentioned estimates significantly. Conclusions All‐ceramic implant‐supported SC s showed—with the exception of a RNC material—high survival rates. However, failures and technical complications occurred which have to be considered when informing patients on the treatment with implant‐supported all‐ceramic SC s.
