Procera AllCeram Crowns (procera + allceram_crown)
Selected AbstractsAnterior Esthetic Rehabilitation on Teeth and Dental Implants Optimized with Procera® Technology: A Case ReportJOURNAL OF ESTHETIC AND RESTORATIVE DENTISTRY, Issue 3 2001PASCAL BONNARD DDS ABSTRACT With the latest developments of the Procera® system, all-ceramic crowns have become an attractive solution to provide functional and esthetic rehabilitation on teeth and dental implants. The Procera AllCeram crown and Procera Abutment embrace the concept of computer-assisted design and computer-assisted machining (CAD/CAM) and can be used together for optimal esthetic result. The purpose of this case report was to illustrate the advantages of these new components for complex anterior rehabilitation. Three natural teeth and a Procera Abutment were restored using four Procera AllCeram crowns. Treatment planning and esthetic benefits are discussed. CLINICAL SIGNIFICANCE For complex anterior rehabilitations, the Procera system fulfills both functional and esthetic objectives, providing a new way in the field of esthetic and restorative dentistry. Nevertheless, planning and preparation stages are decisive for successful treatment.

KOKUBO Summary, Procera AllCeram crowns were prospectively evaluated clinically in both anterior and posterior regions in Japanese. One-hundred and one crowns were fabricated for 57 patients at the Tsurumi University Dental Hospital from August 2001 to October 2002 and evaluated according to the California Dental Association (CDA) quality evaluation system at baseline and annually at all follow-up examinations for 5 years. The plaque index (PI) and gingival index (GI) were recorded, and chipping and fracture were checked at the same time as well. A total of 75 Procera AllCeram crowns were evaluated, and the cumulative survival rate was 90·2% over the 5-year clinical trial. Six crowns experienced fractures within the veneering porcelain and from aluminium oxide coping, all of which occurred on the premolar and molar regions, and they had to be removed. Small chipping was observed on three crowns. According to the CDA criteria, 98% of Procera AllCeram crowns were rated as satisfactory, and PI and GI were comparable to those of control teeth during the observation period. [source] Retrospective Clinical Evaluation of 86 Procera AllCeramÔ Anterior Single Crowns on Natural and Implant-Supported AbutmentsCLINICAL IMPLANT DENTISTRY AND RELATED RESEARCH, Issue 2005Fernando Zarone MD ABSTRACT Background: The Procera AllCeramÔ (Nobel Biocare AB, Göteborg, Sweden, and Procera Sandvik AB, Stockholm, Sweden) technique is one alternative to metal-ceramic restorations. However, few long-term evaluations of its use for single crowns on natural and implant-supported abutments are available. Purpose: The aim of the present study was to assess the clinical performance of Procera AllCeram single crowns when placed in aesthetic sites supported by either natural teeth or implants over a period of 48 months. Materials and Methods: Eighty-six single crowns were fabricated and used in 51 patients. The restorations were examined according to the California Dental Association's quality assessment system. Results: One crown was lost after 20 months of follow-up. Of the 85 restorations that completed the 48-month follow-up, only one crown (1.2%) showed a veneering porcelain chip. All crowns were ranked as either excellent or acceptable. The success rates of single crowns supported by natural tooth and implant-supported abutments were 100% and 98.3%, respectively; the total crown success rate was 98.8%. Conclusion: Within the limitations of the present study, Procera AllCeram crowns proved to be a reliable therapeutic choice for the restoration of anterior teeth on both natural and implant-supported abutments. The hybrid glass-ionomer cement used in the present study appeared to be a reliable luting agent. [source] | ||||||||||
