ABSTRACT:
A method of initiating the construction of a new denture from a worn denture includes making a 360.degree. indexed impression mold of the worn denture, including all outer surfaces corresponding to all of a patient's complementary oral tissues, removing the worn denture from the impressionable material in which the mold is formed, filling the mold with a curable liquid, preferably dental acrylic, to form a stint, forming a mated two- layered model onto and around the stint wherein the two-layered model includes a resilient layer and a rigid layer. The resilient layer is placed in undercut areas, defined by the stint, to prevent breaking or cracking upon separating the stint from the two-layered model, the rigid layer is composed of an inelastic material such as dental stone or gypsum, and at least one retention clip is utilized to anchor the resilient layer to the rigid layer. The stint and two-layered model are then placed, together as a case, in plaster, and mounted in an articulator for proper vertical and centric positioning. A baseplate is then constructed and tooth placement information is transferred from the stint to a new wax set-up with modifications as directed by a responsible dentist. The method also allows dental information specific to each patient to be stored for many years in the form of a stint. This information is then available to medical providers if the patient suffers from disease or disfigurement such as from a broken jaw.
