Inlay-retained fixed dental prosthesis have acceptable 3-yr survival rate suggests review

Missing premolar

This review of inlay-retained fixed dental prosthesis included 11 small mainly observational studies. The studies suggest a 3-yr survival rate of 92.6% (95% CI: 85.8-97.6%) and 5-yr survival rate of 87.9% (95% CI: 77.4-96.1%). However because of the low quality of the available studies and the wide range of inlay designs, framework materials, surface treatments and cement systems used means that the results should be interpreted cautiously.

This review of failure rate of single-unit prostheses versus direct restorations in vital posterior teeth included 14 studies (5 RCTs) finding that composite had a significantly higher failure rate than amalgams, regardless of the remaining tooth structure. For teeth with fewer than 2 remaining walls, direct restorations presented significantly higher failure rates than crowns .

17 pro- and retrospective studies were included in this anterior composite restoration performance. While low annual failure rates from 0 – 4.1% were found, there is a need for well-designed clinical trials to evaluate the longevity of anterior composite restorations and investigate the specific factors associated with failure.
