In this prospective clinical trial we observed the 2-year clinical performance of posterior tooth-supported multi-unit fixed dental prostheses (FDP) fabricated from zirconia with monolithic occlusal surfaces. Fifty multi-unit FDPs were inserted in 50 patients. After two years of clinical service, 43 restorations were reexamined as one patient had died and six patients were not available for recall. Two biological (root canal treatment: 12 and 14 months) and one technical (debonding: 12 months) complications occurred. According to the Kaplan–Meier analysis, the success rate was 93.7%, and the survival rate was 100%. The six patients who were not available for regular 2-year follow-up were examined after the official 2-year recall interval, and none of the FDPs presented complications or failures. Within the limitations of the current study, the use of multi-unit FDPs with monolithic occlusal surfaces fabricated from zirconia can be recommended for short-term use in the posterior area.

The aim of this study was to evaluate the clinical performance of the composite pressed on metal framework for full-arch implant-supported fixed prosthesis in order to eliminate the drawbacks related to the chipping of porcelain fused to metal or to zirconia restorations. Sixteen patients received 22 implant-supported screw-cement-retained complete-arch restorations, consisting of composite pressed restorations. All patients were follow-up visit up to 2 years on function (range 24 to 30 months, mean 28.3 months). The outcomes were implant and prosthetic survival rates and calculations of wear determination (mm). After two years of function, the wear values were 95.54�6.88 mm on pressed composite restoration. Using composite pressed restorations appears to be a predictable, esthetic and successful treatment option for method of full arch restorations over implants.

Objectives. The aim of this retrospective study was to evaluate the three-year clinical outcome for ceramic-veneered zirconia fixed dental prostheses (FDPs). Methods. All patients who were treated with ceramic-veneered zirconia FDPs, in three private practices in Sweden, during the period June 2003 to April 2007 were included. Case records from 151 patients, treated with a total of 184 zirconia FDPs (692 units), were analysed for clinical data. All complications noted in the charts were registered and compared to definitions for success and survival and statistical analysis was performed using the Kaplan-Meier method and a Cox regression model. Results. In total, 32 FDPs in 31 patients experienced some type of complication (17.4% of FDPs, 20.5% of patients). Core fractures occurred in two (1.1%) FDPs. Two (1.1%) FDPs or 0.6% of units showed adhesive veneer fractures. Cohesive veneer fractures occurred in 10 (5.4%) FDPs (1.6% of units). The three-year cumulative success and survival rates (CSR) were 82.3% and 95.2%, respectively. Conclusions. Ceramic-veneered zirconia is a promising alternative to metal-ceramic FDPs, even in the posterior area. However, the higher survival rate of metal-ceramic FDPs should be noted and both dentists and patients must be aware of the risks of complications.
