Brief Summary in Scientific Language

Clinical and radiological assessment of long term survival rates and the technical and biological complications of tooth-supported FPDs.
The test bridges are made of full ceramic veneered zirconia frameworks. The control bridges are made with the conventional veneered metal scaffolding.
