<p><P>PROBLEM TO BE SOLVED: To provide an apparatus capable of removing even an implant body strongly bonded with the jaw. <P>SOLUTION: The rotary vibration imparting apparatus comprises: a rotary shaft 106 for transmitting rotary movement from a motor 104; a drive pin 112 eccentrically attached to the rotary shaft 106; a swing shaft 118 extended in a direction orthogonal to the rotary shaft 106 and provided with a polygonal column part 118a insertable to a polygonal hole formed on the implant body on the distal end; and pieces 114 and 116 attached to the swing shaft 118 and provided with two planes which can be abutted on the distal end of the drive pin 112 and is parallel with the swing shaft 118, one of the two planes inclined to the other. When the drive pin 112 is circularly moved around the turning shaft 106 and moved between the planes, the swing shaft 118 is normally rotated/reversely rotated, rotary vibrations are given to the implant body and it is separated from the bone. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
