ABSTRACT:
An apparatus for making and method for forming a dental prosthesis in situ in an edentulouos space defined either adjacent to two existing teeth or between a fixed tooth and a second tooth posterially positioned with respect to the first tooth, and lightly touching the associated gum surface, utilizes a bridge bar assembly having at least one shaped connecting member to be adjustably mounted and connected in the drilled grooves of adjacent teeth, a boss on the bridge bar assembly, and a pontic base adjustably mounted on the boss such that when the bridge bar assembly is in assembled position in the edentulous space for connection to the teeth, the pontic base lightly touches the gum, two spaced mold halves can be placed on the buccal and lingual sides of the edentulous space in which the bridge bar assembly is mounted, (or alternatively, two mold halves with predetermined holes to receive each end of the bridge bar and to permit retention and packing of plastic or pontic forming material), the pontic base can be adjusted relative the associated gum surface to fix the connecting member for the bridge bar assembly relative the drilled section of the teeth, and the edentulous space between the mold halves can be filled with a pontic forming material to form the pontic surrounding the boss on the bridge bar assembly; making the pontic forming material catalytically or chemically set; removing the mold halves; removing the assembly and polishing the sides and undersurface of the pontic or pontics; partially filling the grooves with a filler material; cementing the connecting member in the drilled grooves of the teeth to secure the pontic or pontics in the edentulous space; and applying a cosmetic veneer to the formed pontic or pontics.
