The latest critical summary to come from the ADA-EBD Center is of a 2010 review by Schley et al. The aim of the original review was to assess the 5-year survival rates of all-ceramic zirconia-based fixed dental prostheses (FDPs) and to analyze technical and biological complications.
The reviewer highlighted a number of issues with the review including the use of just a single electronic database (although supported by a manual one) and a lack of a quality assessment of the selected papers. Nine small prospective studies were included with heterogeneity in veneering and ceramic systems. The overall 5-year mean survival rate was 94.29% (95% CI: 58.98-99.32%) for all FDPs but is lower for complication free survival rate to 76.41% (95% CI: 42.42-91.60%) these in the main were technical complications – mainly chipping.
The reviewer also highlights a 2012 review by Raigrodski et al (See Dental Elf 9th March 2012), which included one randomised controlled trial and 11 prospective cohorts with survival rates ranging from 73.9% to 100%.
