There is a lack of evidence based clinical study concerning the use of CAD/CAM fabricated aluminum oxide core crowns and veneers. Purpose. The purpose of the study was to evaluate the clinical performance and predictability of CAD/CAM fabricated aluminum oxide core crowns and veneers after an observation period of one to four years. Material and methods. The study was performed as a retrospective clinical evaluation of all consecutively treated patients treated from January 1, 2004 through June 30, 2007 who provided consent to be included in this assessment. Complications of the crowns and veneers were divided the into four categories: Minor complications (MC), Loosening (L), Veneer fracture (VF) and Failure (F). Survival rate of the restorations were estimated by using Kaplan-Meier statistical analysis. Results. A total of 603 alumina core crowns were placed in 350 patients while 166 alumina core veneers were placed in 53 patients. All restorations were fabricated for premolar, canine or incisor teeth; none of the crowns were used on molar teeth. For the crowns the 4-year cumulative failure rate was 2.79%. By contrast the alumina veneer core veneers demonstrated cumulative failure at 4 years of 23.05%. Conclusion. Based upon this retrospective study of 603 Ceramic crowns and 166 ceramic veneers with a minimum of 12 months and a maximum of 48 months both of which used a high-strength alumina core it appears that the clinical performance of the ceramic crowns (97.1% survival probability) at up to 4 years is far superior to that of the ceramic veneer (63.6% survival probability)."@en . . . .
