Objective: The purpose of this study was to evaluate the clinical performance of Procera AllCeram crowns placed over a 5-year period at three different private dental practices.
Method and materials: Two hundred five Procera AllCeram crowns (50 anterior and 155 posterior) were evaluated in a prospective study from a minimum of 6 months to a maximum of 60 months, with a mean of 23.52 months.
Results: A restoration was considered to be a failure when it impaired esthetic quality or function, thus necessitating remake of the crown. The survival rate was determined with the use of the Kaplan-Meier survival rate, which gave an overall survival rate of 96.7% (100% for the anterior crowns and 95.15% for the posterior crowns).
Conclusion: The Procera AllCeram system seems to have a good prognosis for the posterior teeth and an excellent one for the anterior teeth.
