Twenty-three patients received 45 heat- and pressure-cured composite resin inlays. Approximately 6 months after placement of the inlays, 34 of the inlays (in 19 patients) were examined according to the criteria of the California Dental Association and also for bleeding upon probing. At least 12 months later, 30 inlays (in 16 patients) were reexamined. At the first examination, 28 inlays were rated excellent, three were rated acceptable, and three were rated unsatisfactory. At the second examination, 21 were found to be excellent, eight were acceptable, and one was unsatisfactory. One inlay had been fractured before the first examination, but no other fractured inlays were observed. Except for slightly discolored margins in six inlays, excellent color match and smooth, glossy surfaces were found in most of the restorations.
