ABSTRACT:
A temporary denture can be rapidly produced while the denture user is in a dentist's office by filling a shell member with a molding composition. An impression of the outer surfaces only of a user's permanent denture is made in the molding compound and the tooth portions of the impression are then filled with a quick-cure, tooth colored curable acrylic composition, up to the gingival margin. Before the acrylic has cured, the remainder of the impression is covered with more of the curable acrylic composition which is colored pink until the gingival portion of the impression is covered by a thin layer of the acrylic. After setting, the thus-produced denture shell is removed from the mold, the surfaces thereof are then trimmed to correspond to the starting denture. The inner surface of the denture shell is then filled with soft curable denture liner and fitted in the user's mouth to form the temporary denture. A kit for making such temporary dentures comprises the molding shell; ingredients to form the tooth colored and pink acrylic polymer used to produce the denture shell and preferably also soft curable denture liner to form the inner surface of the finished denture.
