The failure rate of 8% and the drop of the survival probability rate to 90.4% after 10 years of clinical service of Cerec-1 CAD/CAM restorations made of Vita MK I feldspathic ceramic appear to be acceptable in private practice. The three-surface Cerec reconstructions were found to have the most failures. The reasons for the remaining failures were caries (20%) and endodontic problems (7%).
Of these failures, 73% were caused by either ceramic fractures (53%) or tooth fractures (20%). A total of 15 (8%) failures were found in 11 patients. CEREC (Chairside Economical Restorations of Esthetic Ceramics) technology allows you to get dental restorations in. The results were used to classify success and failure.Īccording to Kaplan-Meier analysis, the success rate of Cerec inlays and onlays dropped to 90.4% after 10 years. After 10 years, the clinical performance of the restorations was evaluated using modified USPHS criteria. An adhesive technique and luting composite resin were used for seating the restorations. A study in the International Journal of Computerized Dentistry showed that 87.5 of CEREC inlays and onlays lasted over 27 years of use. The all-ceramic material used for these restorations has high strength properties and is durable. The restorations were fabricated chairside using the Cerec-1 computer-aided design/manufacturing (CAD/CAM) method and Vita MK I feldspathic ceramic. Stronger material: CEREC restorations are favored for being truly long-term. Of 200 Cerec inlays and onlays placed in a private practice between 1989 and early 1991, 187 restorations were observed over a period of 10 years. The objective of this follow-up study was to examine the performance of Cerec inlays and onlays in terms of clinical quality over a functional period of 10 years.
