DENTAL BRIDGE Russian patent published in 2001 - IPC

FIELD: medical engineering. SUBSTANCE: prosthesis has supporting artificial crowns for fixing them on the abutment teeth, hingedly connected to the corresponding end zones of intermediate parts reproducing anatomic shape of failing teeth. The hinged link has a socket made in the end zone of the intermediate part, an ear rigidly fixed on the abutment crown, a damping member which parts are arranged between the lateral sides of the ear and socket and a connection axle coming through ear opening, a damping member opening and openings in intermediate part walls. The connection axle is longitudinally movably mounted in the opening. Ear opening has oval shape with greater horizontal axis, its vertical dimension being at least equal to connection axle diameter, the horizontal one is greater than the diameter. EFFECT: compensated longitudinal forces acting upon abutment crown not loaded with chewing pressure; reduced torque and dislocating moments. 4 cl, 10 dwg
