title: Clinical evaluation of an all-ceramic restorative system: 24-month report.
abstract: OBJECTIVE
  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
  40 posterior and anterior crowns, 20 all-ceramic inlays and onlays, and 26 veneers were placed in 43 patients. 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. A majority of restorations (95-100%) were evaluated to be optimal at baseline (B), 6, 12, and 24 months using a modified Ryge criteria for the following categories: color match, marginal adaptation, porcelain staining, secondary caries, postoperative sensitivity, and retention.
  
  
  RESULTS
  There were sufficient shades available to obtain desired esthetic result with 98% of all restorations being rated Alfa for shade match to Vita Lumin shade guide. The overall 2-year success rate (inlay/onlays, crowns, and veneers) was 98.75%.
