METHOD AND DEVICE FOR FITTING DENTAL BRIDGE PROSTHESIS STRUCTURE Russian patent published in 2002 - IPC

FIELD: medicine; medical engineering. SUBSTANCE: method involves determining dental bridge prosthesis reference plane and patient jaw reference plane. Elongation members are fixed on each supporting member. The dental bridge prosthesis structure and the model are fixed before the real fitting process beginning in a way that their reference planes belong to some predefined plane. Instrument for shortening each of the elongation members and each of the connection members are controlled in a way that their end surfaces retain their parallel relation relative to the predefined plane. The connection members are shortened to the extent providing their end surfaces to be arranged at distance b from the predefined plane, b being equal to the distance separating magnetic holder plane and end cutting member position. The elongation members are turned so that their end face surfaces were remote from the predefined plane at a distance c = a-b, where a is the total model and dental bridge prosthesis structure height in the perpendicular direction with respect to the reference planes. EFFECT: optimum correspondence of supporting members in patient jawbone; high accuracy of fitting. 10 cl, 4 dwg
