Purpose: The aim of this article was to study frequencies and distribution of remakes of
all-ceramic inlays/onlays, veneers, and crowns occurring before and after cementation.
Materials and Methods: A total of 2,069 sintered feldspathic ceramic restorations
(Colorlogic) and 1,136 pressure-molded ceramic restorations (IPS Empress 1 and 2) were
produced during the study period by one dental laboratory. The laboratory gave an
unqualified and unlimited guarantee for their ceramic restorations. The outcome variable
was reports from the clinicians to the dental laboratory about any problems related to the
restoration, necessitating remake. Results: Problems occurring before cementation
occurred in 4.4% of the restorations. Veneers were remade more frequently than the
other types of restorations (6.6%). After cementation, the overall 2-year rate of remakes
was 1%, indicating a survival rate of the ceramic restorations of 99%, with inlays/onlays
exhibiting the highest (99.8%) and crowns the lowest (98.4%) rates. This difference in
rates was significant. No significant differences in remakes between ceramics or tooth
categories were found. Conclusion: There were few problems in a short- to medium-term
perspective that, in the opinion of general practitioners, necessitated remakes of allceramic
restorations. Int J Prosthodont 2003;16:621–625.
