METHOD OF MANUFACTURING FOR ADDITIONAL LOCK FASTENING OF CLASP TELESCOPIC PROSTHESES Russian patent published in 2012 - IPC A61C13/267 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, namely to orthopedic dentistry and can be used in manufacturing of clasp telescopic prostheses with additional lock fastening. Method of manufacturing of additional lock fastening for clasp telescopic prosthesis includes several stages. At the stage of modelling wax reproduction of internal telescopic crowns on their distal surfaces performed is installation of additional lock fastenings in form of industrial workpieces of attachment with preservation of diametrical location of support teeth. Casting from metal of internal telescopic crowns with spherical projections is carried out. Fixation of medium rigidity matrices is performed on spherical projection of internal telescopic crown, model is prepared for process of duplication with isolation of clearance between lower matrix surface and mucosa of prosthesis bed. Wax modelling of framework of clasp telescopic prosthesis with external telescopic crowns on fireproof model is carried out. After casting framework of clasp prosthesis by traditional method, inside framework of detachable part of clasp prosthesis socket for installation of matrices under spherical projection is formed. After casting framework of clasp prosthesis by traditional method, fitting of metal construction without matrices is performed.

EFFECT: increased quality of prosthetics due to application of additional lock fastening, with possibility of its re-activation and ensuring prolongation of prosthesis service terms, without essential change of traditional process of manufacturing of telescopic clasp prostheses.
