Abstract

The purpose of this study was to evaluate the clinical strength of castable glass-ceramic (OCC, Olympus Optical Co., Japan) restorations.<BR>On 38 patients, from February 8, 1994 to December 19, 1996 at Aichi-Gakuin University Dental Hospital, 154 castable glass-ceramic restorations were cemented.<BR>These restorations were reexamined February 1998 and an analysis of fractures in the restorations was performed. Observed fractures as well as cracking or chipping and 22.7% of the restorations were considered fractured, and the longest survival time until now has been 48 months. The Kaplan-Meier survival probability calculated for these restorations was 0.86 using Panavia 21 and 0.90 using Panavia EX after a time interval of 24 months, and 0.66 using Panavia 21 and 0.82 using Panavia EX after a time interval of 36 months. There were no significant differences in the survival between the two cements.<BR>It was then con cluded that castable glass-ceramic restorations are suitable for clinical use, although some problems remain, especially with the successful lifetime of the castable glass-ceramics.
