A 5-YEAR EVALUATION OF CERAMIC INLAYS (CEREC)

The intention of this study was to evaluate the clinical function of p orcelain inlays made with the Cerec technique after 5 years. 115 inlay s were produced in 46 patients and of these were 51 inlays evaluated. Epoxy models were made from impressions and the gap width and depth wa s measured in a microscope. SEM pictures were also produced to illustr ate the ditching. The measured mariginal defects showed a mean width a nd depth of (SD) 373 (147) and 111 (67) mu m respectively. No signific ant differences of the ditchings could be detected between molars and premolars. Only 3 inlays were found to be fractured of all inlays prod uced.
