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

Purpose: To clinically evaluate an all-ceramic restorative system (Finesse All-Ceramic) when used in conjunction with an ultra-low fusing porcelain (Finesse) using bonded esthetic resin cements (Enforce & Calibra).

Methods: This report describes the 3-year results of a prospective, consecutive case clinical evaluation for Finesse All-Ceramic. Forty posterior and anterior crowns, 20 all ceramic inlays and onlays, and 26 veneers were placed in 43 patients at the initiation of this study. Standard ceramic preparations were performed followed by conventional polyvinylsiloxane (Aquasil) impression techniques using cord retraction. The bonded resin cement was used to place the restorations following manufacturer's instructions.

Results: 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%.
