Dr. Chandur Wadhwani published his latest research in the Journal of Esthetic and Restorative Dentistry.
The article describes a novel technique with the addition of a pressed porcelain abutment margin capable of bonding to the porcelain margin of an implant crown restoration. This allows for supragingival margin placement, reduces the potential effect of excess cement-induced peri-implant disease, and provides a controlled environment for the bonding process. Another advantage is the matching esthetics of the crown and supporting abutment, which in the event gingival recession occurs, the restoration appears as a longer tooth without the risk of exposing an underlying abutment margin with different esthetic properties.
