title: AllCeram crowns for single replacement implant abutments.
abstract: Clinicians who are comfortable with traditional porcelain fused to metal restorations may find the thickness of veneering porcelain addition to the CeraOne single tooth ceramic cap disconcerting. When using a premanufactured ceramic cap to fit the space of the final restoration, substantial amounts of "unsupported" veneer porcelain may be required to achieve tooth contact to adjacent or opposing dentition. A potential problem of weak, unsupported veneer porcelain has been addressed by a modification of an existing manufacturing process. By using CAD/CAM technology, a custom-designed Procera AllCeram coping can be created for the implant abutment that eliminates any concerns regarding the resultant design of the underlying ceramic cap substructure.
