Posterior Implant-Supported Modified Monolithic Zirconia and Metal-Ceramic Single Crowns: 5 Years Study : Randomized Controlled Clinical Trial to Compare Posterior Implant-Supported Modified Monolithic Zirconia and Metal-Ceramic Single Crowns: 5 Years Study
The outcome of implant therapy has been presented in the majority of clinical studies by focusing only on implant survival without providing detailed information on the reconstructions . However, for decision making, it is important to know the survival rates and the incidence of biological and technical complications not only for the implants but also for the reconstructions. Thus, the selection of restoration materials should be based on proper optical characteristics in addition to biocompatibility and sufficient strength of materials. Monolithic zirconia has been used in posterior region, especially for single crowns, in order to eliminate the veneer cracking, But Since monolithic zirconia are relatively new, few randomized, controlled clinical studies have evaluated their success. There is only one study identified regarding the performance of monolithic ceramic restorations bonded to Ti inserts, investigating the clinical outcome of using monolithic or modified monolithic zirconia implant-supported single crowns and comparing outcomes and complications of metal-ceramic and monolithic or modified monolithic zirconia implant supported single crowns. More clinical studies to evaluate the performance of CAD/CAM monolithic implant-supported restorations bonded to Ti inserts and bases and compare their survival, success and complication rates with other restorative options [with a mean follow-up period of at least 5 years are required for a meaningful interpretation of the survival and complication rate . So this study aims to investigate outcomes and complications of implant supported modified monolithic zirconia and metal-ceramic single crowns in the posterior region of the mouth. The null hypothesis is that there is no difference between modified monolithic zirconia and metal-ceramic posterior implant-supported SCs in prosthetic complication rates..
