Balmer M, et al. - Experts assessed clinically and radiographically the outcome of zirconia oral implants after 3 years in function. They used a linear mixed model to evaluate statistically the influence of prognostic factors on changes in the marginal bone level. High survival rate and a low marginal bone loss were demonstrated by the investigated one-piece zirconia implant after 3 years in function. For single-tooth replacement and 3-unit fixed dental prosthesis (FDP), the implant system was seen to be successful.
