The Procera AllCeram system.

The Procera AllCeram system is indicated for manufacturing all-ceramic crowns for single-tooth restorations in the anterior and posterior regions. In addition, it is possible to create metal-free superstructures on CeraOne abutments from the Brånemark implant system or crowns on individually prepared aluminum oxide abutments (CerAdapt). The Procera copings, which are manufactured using computer-aided design/manufacturing technology, are characterized by very good mechanical properties. Ceramic veneers tailored to the copings offer excellent esthetics, favorable abrasion behavior, and an ideal surface structure for non-inflammatory apposition of the periodontal or periimplant tissues. The present article offers an overview of previous scientific studies, describes clinical and laboratory procedures, and presents case reports.

Procera: a new way to achieve an all-ceramic crown.

The Procera System embraces the concept of computer-assisted design and computer-assisted machining to fabricate an all-ceramic crown composed of a densely sintered, high-purity aluminum oxide coping combined with a compatible veneering porcelain. Strength, precision of fit, color stability, cementation, and wear characteristics are among the many factors that concern clinicians when fabricating all-ceramic restorations with this new crown system. This article presents, in summary form, the data from the many studies on Procera AllCeram crowns that have been conducted at clinical and laboratory centers around the world. The evidence reported in these studies clearly demonstrates that the Procera AllCeram crown represents a combination of computer technology and creativity for which a positive prognosis can be made. Today its application is restricted to single crowns; however, with continued development, multiple unit all-ceramic anterior and posterior fixed partial dentures are clearly in the future.
