PROCERA - A NEW WAY TO ACHIEVE AN ALL-CERAMIC CROWN

The Procera System embraces the concept of computer-assisted design an d computer-assisted machining to fabricate on all-ceramic crown compos ed of a densely sintered, high-purity aluminum oxide coping combined w ith a compatible veneering porcelain. Strength, precision of fit, colo r stability, cementation, and wear characteristics are among the many factors that concern clinicians when fabricating all-ceramic restorati ons 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. Th e evidence reported in these studies clearly demonstrates that the Pro cera AllCeram crown represents a combination of computer technology an d creativity for which a positive prognosis can be made. Today its app lication is restricted to single crowns; however; with continued devel opment, multiple unit all-ceramic anterior and posterior fixed partial dentures are clearly in the future.
