METHOD OF PREPARING GYPSUM MODEL OF JAW BEFORE PACKAGE OF BASIC PLASTIC Russian patent published in 2015 - IPC A61C13/00 A61C9/00 

FIELD: medicine.

SUBSTANCE: in oral cavity of patient in prosthesis bed flexibility of mucous membrane is measured in oral cavity of patient in prosthesis. Borders of poorly flexible areas are determined. Before packing basic plastic paste on model in cuvette, on prosthesis bed borders of poorly flexible areas are outlined. They are extended for 1.5-2 mm in towards flexible areas. Durable insulating material with width not less than value of flexibility of mucous membrane is fastened on said extended boarders of poorly flexible areas. Cuvette with gypsum model is filled with paste of basic plastic and placed under the press. Plastic polymerisation is carried out. After polymerisation prosthesis is extracted from cuvette and processed.

EFFECT: method, due to preparing gypsum model of jaw before packaging basic plastic, makes it possible to reduce excessive pressure, trauma and atrophy of prosthesis bed tissues in the area of poorly flexible areas of prosthetic bed.
