title: A one-year clinical study of indirect and direct composite and ceramic inlays.
abstract: The aim of this study was to evaluate the clinical performance of four types of tooth-colored inlays. The systems included 15 direct ceramic inlays (CEREC Vita-Blocks), 15 direct composite inlays (Brilliant D.I., Coltène), 14 indirect ceramic inlays (Vita Dur N), and 14 indirect composite inlays (Estilux) in 37 patients. The inlays were evaluated clinically 1 wk (base line) and 6 and 12 months after cementation. The clinical assessments were supported by bitewing radiographs. One Vita Dur N inlay fractured after 1 yr of service, and one Brilliant D.I. inlay had to be replaced because of secondary caries. No apparent increase in plaque accumulation or gingival inflammation could be related to treatment with inlays. At base line and throughout the observation period, the Vita Dur N inlays received the highest ratings for morphology and color match. The Brilliant D.I. inlays showed the smoothest surface texture, whereas the Estilux inlays showed the roughest texture. After 6-12 months of observation, all types of inlays showed varying degrees of disintegration of the composite luting cement. Within the observation period, all inlay systems appeared to be clinically acceptable.
