DEVICE FOR MAKING MAGNETIC FIXATION OF REMOVABLE DENTURE Russian patent published in 2002 - IPC

FIELD: medical engineering. SUBSTANCE: device has plates manufactured from magnetically soft and magnetically hard material set in alternating order in the removable part of prosthesis and a plate manufactured from magnetically soft material mounted on the fixed part of the prosthesis. Two wedge-like plates manufactured from magnetically soft material increasing attraction force between the fixed and removable parts of the prosthesis are adjacent to the larger facets of a plate manufactured from magnetically hard material in the removable part of prosthesis. Convex and concave surfaces of the fixed and removable prosthesis parts are shaped as cylinder surface which axis is in parallel relation to the dental row. EFFECT: reliable attachment of the removable prosthesis part to the fixed one; low consumption of rare-earth elements; small forces required for taking off the removable part of prosthesis. 2 cl, 2 dwg
