Abstract
A dental press or jig for rigidly positioning during a short curing period, a matching pair of dentures held in occlusal alignment with one or both having a contacting layer of relining material pressed against a respective model of the patient's mouth, all clamped together by the press within a body of plaster of Paris. The laterally-open press is formed of a pair of annular plates or disks, vertically spaced apart a constant distance by three, upstanding, peripheral posts which are thus tensioned against opposite faces of the composite workpiece. Each plate is formed with plaster escape-channels leading to catch basins on the outer faces, the basins being defined by a reinforcing pattern of diametric ribs within a peripheral rim which render the plates unbendable under pressure. The assembly may be molded of glass-reinforced terephthalate resin for high tensile and flex resistant properties.
