The present invention relates to a dental implant and, more specifically, to a dental implant which: includes an upper impact buffering unit comprising one or more horizontal penetrating holes on a lower coupling axis of an abutment； includes a lower impact buffering unit comprising cutting units which form coupling legs or other horizontal penetrating holes at the lower part of the upper impact buffering unit； and arranges the horizontal penetrating holes of the upper impact buffering unit and the cutting units or other horizontal penetrating holes of the lower impact buffering unit to be crossed each other in a circumference direction of the abutment: thereby the upper impact buffering unit and the lower impact buffering unit of the abutment complementarily absorbing stress applied from outside and, as a result, minimizing dead zone of stress dispersion of bite force against the abutment through even dispersion of the stress applied from outside. The present invention: arranges the horizontal penetrating holes of the upper impact buffering unit and the cutting unit or other horizontal penetrating holes of the lower impact buffering unit to be crossed each other in the circumference direction of the abutment, thereby evenly allocating material rigidity or impact absorbing power of the abutment through 360°； of cross section of the abutment. As a result, the present invention more efficiently disperses pressure or impulsive force applied from outside to whole surface, thereby maximizing impact buffering effects while removing dead zone of stress dispersion and, furthermore, obtains durability of the implant and excellent effects of extending serivce life.본 발명은 치과용 임플란트에 관한 것으로서, 지대주의 하부 체결축에 적어도 하나의 수평 관통홀로 이루어진 상부 충격 완충부를 구비하고, 상기 상부 충격 완충부의 하부에는 체결 레그를 형성하는 절개부 또는 또 다른 수평 관통홀로 이루어진 하부 충격 완충부를 구비하고, 상기 상부 충격 완충부의 수평 관통홀과, 상기 하부 충격 완충부의 절개부 또는 또 다른 수평 관통홀은 지대주의 원주방향으로 상호 엇갈려서 배치됨으로써, 외부로부터 가해지는 응력을 지대주의 상부 충격 완충부와 하부 충격 완충부가 상호 보완적으로 흡수하게 하며, 결과적으로 외부로부터 가해지는 응력의
