摘要：
The present invention relates to a dental implant related to artificial teeth and, more specifically, to a dental implant, which includes a fixing body having an upper portion with a shaft hole, and implanted into the jawbone, and an abutment consisting of a lower fastening shaft portion inserted into the shaft hole of the fixing body to be coupled to the fixing body, and an upper mounting portion, on which a prosthetic appliance is mounted. The dental implant also comprises: an impact buffering portion having a cut portion therein as the lower fastening shaft portion of the abutment consists of at least two fastening legs； a fastening portion formed on an outer surface of the impact buffering portion； and a deformation control portion protruding inside the fastening legs to form a gap (d1) of the cut portion narrower than a gap (d2) of the cut portion inside the fastening portion so as to restrict an excessive bending of the lower fastening shaft portion caused by an external force. According to the present invention, the deformation control portion can restrict an excessive bending of the fastening shaft caused by an external pressure after the operation of an implant to increase a clamping force of the fastening shaft in the shaft hole of the fixing body, thereby fixing the implant stably. In addition, an external pressure can be sufficiently dispersed through the fastening shaft not to apply an excessive force to connections between the abutment and the fastening legs, thereby improving the durability of an implant and extending the life of the implant.본 발명은 인공치아에 관련된 치과용 임플란트에 관한 것으로, 상부에 축공을 형성하고 턱뼈에 식립되는 고정체, 및 상기 고정체의 축공에 삽입되어 상기 고정체와 결합되는 하부 체결축부와 보철물이 장착되는 상부 장착부로 이루어진 지대주를 포함하는 치과용 임플란트에 있어서, 상기 지대주의 하부 체결축부가 적어도 두개의 체결레그로 이루어져 내부에 절개부를 형성하는 충격 완충부； 상기 충격 완충부의 외면에 형성된 체결부； 및 외력에 의한 체결축부의 과도한 휘어짐을 제한하도록, 상기 체결레그의 내측 방향으로 돌출되어 상기 체결부 내측의 절개부 사이간격(d2) 보다 좁은 절개부의 사이간격(d1)을 갖는 변형 제어부；를 구비한 치과용 임플란트를 제공한다. 본 발명에 의하면 임플란트가 시술된 후에는 외압에 의해서 변형 제어부가 체결축의 과도한 휘어짐
