FIELD: medicine. ^ SUBSTANCE: invention relates to field of medicine, namely to orthopedic dentistry, and can be used for manufacturing detachable dental prostheses. In manufacturing detachable dental prosthesis impression of part of oral cavity for which prosthesis is made is obtained, said impression is used for making wax model of part of oral cavity for which prosthesis is made with further formation of plaster model with wax composition in flask for free casting with application of forming mass from plaster. Artificial teeth are installed into forming mass corresponding to their imprints. Forming mass is kept until it hardens, wax is removed from flask by means of hot water, without extracting teeth. Plaster model and plaster flask are died in convection oven at temperature 170 degrees for 120 minutes. After plaster model drying and application of disconnecting lacquer plaster model and plaster flask are connected and composition is filled in. Composition contains diphenylmethane diisocyanate, polyatomic alcohol and catalyst. After composition polymerisation prosthesis is removed and finally improved. ^ EFFECT: increase of accuracy of teeth positioning, method simplification, reduction of time and cost of dental prosthesis. ^ 1 ex |
