Abstract: A human body implant structure includes: a support anchor which is embedded into a bone body; a support base which is placed on and fixed to an upper portion of the support anchor; and a lost-part compensation part which is mounted on an upper portion of the support base, wherein the support anchor and the support base are configured to be detachably fitted to each other by way of the taper fitting structure where the support anchor and the support base are brought into close contact with each other, and a stepped portion which is formed of an upper surface of the support anchor is formed on a boundary between a female threaded hole which is vertically formed in the support base and a vertical hole formed in the upper surface of the support anchor.

Abstract: A dental implant is provided that can be firmly fixed in an oral cavity, even if the amount of bone required to embed the implant is small. A necessary amount of bone can be secured by generating new bone so that the fixture part of the implant can be fixed in the bone. The fixture part of the implant includes several members movably connected to each other so that the fixture part is adjustable in length. The fixture part includes a first member made up of an uppermost member, a middle member, and an end member. It is preferred that the middle member be cylindrical or rod-shaped with male screws extending radially outwardly from an outer circumferential periphery thereof. The fixture part also includes a second member which is a hollow cylinder. It is preferred that the hollow cylinder have a tapped hole on one end with female screw on an inner periphery thereof so that the middle member of the first member can be screwed into the second member.
