The present invention relates to a magic threader for a dental implant and, more specifically, to a magic threader for a dental implant which specifies the thickness of a threader unit, and the height and pitch of a screw thread, by considering the strength difference of titanium and bone, so as to maximally reduce the stress intensity of an alveolar bone caused by the thread unit, and prevent damage to an alveolar bone, thereby increasing bonding strength under a stable structure, and which configures the thread unit in a square plate form and specifies the screw thread angle within a certain numerical range such that only compression in one direction (direction A) of the thread unit with respect to the alveolar bone is performed, the compression can be minimized in direction B or direction C inclined with respect to direction A, and stress dispersion can be maximized.
