The intention of this study was to evaluate the clinical function of porcelain inlays made with the Cerec technique after 5 years. 115 inlays were produced in 46 patients and of these were 51 inlays evaluated. Epoxy models were made from impressions and the gap width and depth was measured in a microscope. SEM pictures were also produced to illustrate the ditching. The measured marginal defects showed a mean width and depth of (SD) 373 (147) and 111 (67) microns respectively. No significant differences of the ditchings could be detected between molars and premolars. Only 3 inlays were found to be fractured of all inlays produced.
