A magic threader for a dental implant is disclosed, particularly, a dental implant capable of increasing coupling strength under a stable structure by specifying thickness of a thread portion, and pitch between thread portions in consideration of a difference in strength between titanium and bone to decrease stress of an alveolar bone by the thread portion and prevent damage to the alveolar bone and is capable of conducting compression of the thread portion for the alveolar bone in only one direction (direction A), minimizing compression of the thread portion for the alveolar bone in a direction B or a direction C inclined with respect to direction A, and maximizing stress dispersion by configuring the thread portion in a rectangular plate shape and specifying an angle of the screw thread in a specific numerical range.
