REMOVABLE DENTURE AND METHOD OF ITS MANUFACTURING Russian patent published in 2010 - IPC A61K6/09 A61C13/07 A61C13/07 

FIELD: medicine.

SUBSTANCE: invention relates to field of orthopedic dentistry. Removable denture includes elastic pad and rigid basis with artificial teeth. Rigid basis is made from polyurethane composition based on di-isocyanate and polyatomic alcohol, where as di-isocyanate used is pseudoforpolymer, containing NCO-groups in amount 16.5-17.0%, and as polyatomic alcohol, used is polyoxypropylene and/or oligooxypropylene-polyatomic alcohols with definite molecular weight. Elastic pad of denture is made from polyurethane composition based on poly-isocyanate with content of NCO-groups from 2.2 to 33.1%, oligopolyatomic alcohol, such as oligooxypropylene glycol or olygooxypropylenetriol with moleculare weight from 500 to 5000, and catasyst - dibutyldilaurate of octoate of tin. Polyurethane compositions can contain additional components such as dyes, light-stabiliser, ethylene glycol, etc. Polyuretghane compositions, of which removable denture is made, and method of denture manufacturing ensure increase of removable denture basis hardness, increase of strength characteristics of denture material with simultaneous increase of service life of manufactured removable denture, as well as improvement of technological characteristics in process of denture manufacturing.

EFFECT: there is claimed removable denture and method of its manufacturing.
