Claim Text:
1. A human body implant structure adapted for adjustment with a separation jig having a threaded length portion, the implant structure comprising: a support anchor which is configured to be 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 provide a tapered fit structure comprising contacting tapered surfaces of the support anchor and support base, the tapered fit structure configured to detachably hold the support anchor and support base together, during use of the human body implant structure, without using either one of cement adhesion or screw thread engagement, and wherein 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, and wherein the support anchor and the support base are further configured so that when the human body implant structure is positioned relative to the separation jig, the separation jig threadingly engages the female threaded hole of the support base so that when the separation jig is turned in a given direction, the separation jig threaded length portion advances along said female threaded hole of the support base while an end portion of the separation jig abuts an end portion of a screw rod of said support anchor, whereby the support base is pushed out of a tapered fit with said support anchor separating the support base from the support anchor so as to enable said adjustment of the human body implant structure.
