    Abstract:
    STATEMENT OF PROBLEM: Esthetic demands of patients and practitioners for an all-ceramic crown in both anterior and posterior regions of the dental arches has prompted the development of the Procera AllCeram crown. Long-term clinical trials that evaluate the strength and naturalness of the Procera AllCeram crown are lacking. PURPOSE: This prospective study was initiated to evaluate the clinical performance of 100 Procera AllCeram crowns after 5 years in service. MATERIAL AND METHODS: One hundred Procera AllCeram crowns were fabricated for 58 patients (20 men and 38 women). Patients were treated by 4 general dental practitioners. Crown placement involved both the anterior and posterior regions of the dental arches. Crowns were examined at baseline and once a year during the 5 years that followed and evaluated at each appointment with the California Dental Association's quality assessment system. RESULTS: Of the 97 crowns remaining in the study after 5 years, only 3 crowns had experienced a fracture through the veneering porcelain and the aluminum oxide coping material. Two additional crowns were replaced as a result of fractures of only the veneering porcelain. One crown was replaced as a result of recurrent caries. All remaining crowns were ranked as either excellent or acceptable for surface/color, anatomic form, and marginal integrity. CONCLUSION: The 5-year clinical observations and ranking with the California Dental Association's quality assessment criteria supported the conclusion that Procera AllCeram crowns may be used in all areas of the mouth.
