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.
