PROBLEM TO BE SOLVED: To provide a dental implant keeper to be fixed within an inner oral cavity side of an abutment disposed within an inner oral cavity side of a dental implant fixture, whose main body can be easily removed when an attracted surface attracted to a magnet structure fixed on an inside of a denture by magnetic attraction force is distorted or damaged. SOLUTION: A keeper body 4a made of a magnetic material is supported by an end flat surface 2d which is provided within an inner oral cavity side so as to be perpendicular to the axis of the abutment 2. The keeper body 4a is finally fixed on a dental implant fixture 1 with a male screw 4d, which is rotated by an engaging part 4e engageable with a driver and/or a wrench positioned at a central part of the keeper body 4a. The engaging part 4e is provided to be positioned on a dental implant fixture 1 side from an attracted surface 4b within an inner oral cavity side of the keeper body 4a. COPYRIGHT: (C)2006,JPO&NCIPI
