Abstract
The present invention relates to an abutment screw-separable dental implant structure in which an abutment is fastened and fixed to a fixture implanted in an alveolar bone through an abutment screw, and more particularly, to a dental implant structure in which, as a head part of an abutment screw protrudes upward from a post of an abutment without being accommodated in the abutment, a diameter (inner diameter) of an inner space of the abutment may be reduced to freely form a diameter and thickness of the post of the abutment to a desired size.
