Brandt S, et al. - Investigators assessed the survival rates of zirconia-based tooth/implant restorations among 126 telescopic overdentures. They measured survival rates and modifying factors by Kaplan-Meier analysis, log-rank testing, and Cox regression analysis. A 5-year prosthesis survival of 96.9 ± 2.2% was recorded. Overall, they considered the concept of conical zirconia telescoping into electro-formed gold, a viable alternative to other telescopic designs used for removable dental prostheses. They suggested the concept well adapted for tooth/implant-supported prosthetic restoration.
