PURPOSE: A dental implant is provided to heighten the dispersion function of an occlusion force by increasing the initial fixing force and strengthening the self-tapping, when transplanted in an alveolar ridge, and to allow the strong supporting force, acting against vertical and lateral pressure. CONSTITUTION: The dental implant(2), which is transplanted in an alveolar bone so as to build up a tooth root, includes: a main body(4), on whose entire outer circumference a thread with a regular pitch and angle is formed; a first taper portion(6), configured so that it is arranged at a 5 to 15 deg. inclined angle on the upper portion of the main body(4) and tapered in the direction of the lower end of the main body(4); a second taper portion(8), arranged at a 5 to 15 deg. inclined angle on the lower portion of the main body(4) and tapered in the direction of the lower end of the main body(4); a table(10), arranged on the upper end of the first taper portion so as to be seated by a crown; and a bevel(12), arranged between the first taper portion(6) and the table(10).
