Clinical evaluation of an all-ceramic restorative system: a 36-month clinical evaluation.

Abstract

A majority of restorations (95-100%) were evaluated to be optimal at baseline (B), 1 month, 12, 24 and 36 months using a modified Ryge criteria for the following categories: color match, marginal adaptation, porcelain staining, secondary caries, postoperative sensitivity, and retention. Assessment of color match at 36 months resulted in 97% of all crowns and 100% of all veneers and onlays being rated alfa for shade match to Vita Lumin shade guide. The overall 3-year success rate at the 3-year recall (inlay/onlays, crowns, and veneers) was 98.57%, with the success rate for crowns and veneers at this time period being 100%.
