ABSTRACT:
An improved dental bridge and method of construction thereof is disclosed. The bridge has no exposed metal. The abutment teeth are prepared and have opposing notches cut into the occlusal surfaces thereof. Impressions are made and a master and opposing model prepared therefrom. The model abutment teeth are prepared as dies and a refractory model then developed from the master model. A metal pontic rod is prepared, opaqued, and installed in the refractory model notches. After coating the abutment teeth and pontic rod with a porcelain mix and curing, all porcelain crowns are built over the abutment models and one or more all porcelain pontics are built over the pontic rod. After curing and glazing of the dental bridge, the refractory model is cut away from the bridge.
