<p>PURPOSE: To easily absorb force generated during a chewing operation in the same way as natural teeth by providing the implant with an elastic force attenu ation means provided with a double-truncated-head silicone rubber body. CONSTITUTION: In a hole 56 formed into a long main body 50, an elastic force attenuation means 90 is arranged. A first function of the elastic force attenuation means 90 maintains contact of a carrier body 16 and a head 36 when a chewing operation is not performed. A second function mitigates chewing force received by a base shaft 30 while teeth implant is used against an axial moving of a teeth assembling body in a second direction along the base shaft 30. The elastic force attenuation means 90 is bitruncated conical body 92 made of an elastic silicone rubber 93 to be used by being combined with a truncated conic hole 58 formed in the long main body 50, in which an opening 96 passing through is formed. In this opening 96, part of a silicone rubber body is made to be received when the silicone rubber body is compressed by chewing force received while the teeth implant is used.</p> |
