Abstract : Introduction: Dental CAD/CAM technology has been available for over 25 years for the fabrication of inlays/onlays, crowns, endocrowns, and veneers. However, very few long-term studies have evaluated the longevity of these restorations. The primary advantage to CAD/CAM fabrication of restorations is the ability to produce a ceramic restoration in one appointment without the need for a laboratory. Areas of concern with these restorations include fracture potential, marginal integrity, and aggressive preparation to allow for milling of the restoration. Most studies conducted have reported only 2-3 years of data, following a relatively small numbers of restorations. To the authors knowledge, only one study has reported a mean restoration exposure time of over 10 years. Objective: To determine the longevity of single-tooth all-ceramic CAD/CAM-fabricated dental restorations.Methods: An English language search from 1985 to 2012 was performed in two databases: PubMed and Embase. Using pre-established inclusion and exclusion criteria, all articles identified by the search strategy were reviewed by title, then by abstract, and then by full text reading. Data were assessed by two independent examiners. The primary outcome was the percent of intact restorations at the study conclusion (survival rate), with confidence intervals calculated using the exact binomial method. This survival rate was pooled by using the random effects method.
