A 5-YEAR CLINICAL-EVALUATION OF CERAMIC INLAYS (CEREC) CEMENTED WITH A DUAL-CURED OR CHEMICALLY CURED RESIN COMPOSITE LUTING AGENT

Sixty-six class-II CAD/CAM-manufactured ceramic inlays (Cerec) were pl aced in 27 patients. Each patient received at least one inlay luted wi th a dual-cured resin composite and one inlay luted with a chemically cured resin composite. The inlays were examined 5 years after luting u sing the California Dental Association (CDA) criteria. Eighty-nine per cent of the 66 inlays were rated 'satisfactory'. During the follow-up period replacement was required for 3 inlays because of inlay fracture s (4.5%) and 1 inlay because of fracture of the tooth substance (1.5%) . All those inlays were luted with the dual-cured resin composite luti ng agent. Of the remaining 62 inlays the CDA rating 'excellent' was gi ven to 84% for color, 97% for surface, and 81% for anatomic form. 'Exc ellent' margin integrity was seen in 52% of the dual cured resin compo site luted inlays and in 61% of the chemically cured resin composite l uted inlays. No statistically significant (P > 0.05) difference was ob served between the two luting agents.
