Abstract: A system for constructing temporary bridges to fill edentulous spaces found between a pair of abutment teeth in a human mouth is disclosed. The system contemplates selecting an appropriate prefabricated temporary bridge mold from a selection of pre-sized molds. The portion of the prefabricated temporary bridge mold which corresponds to the edentulous space and flanking abutment teeth is selected and cut away and retained as a mold subsection. The mold subsection is then filled with acrylic mix, and placed on top of the edentulous space and flanking abutment teeth such that the flanking abutment teeth form hollowed cavities in the cast temporary bridge which is formed upon the hardening of the acrylic mix.
