The present invention relates to a dental implant. The dental implant comprises: an alveolar bone insertion member (100) which has an opening formed on an upper part thereof, has a space formed therein, has an inner space that becomes smaller from an upper part to a lower part thereof, has a cutout part (110) formed to allow the lower part thereof to be split into multiple parts, at a lower part thereof, and is inserted into an alveolar bone； an opening induction member (200) which is inserted in the inner space of the alveolar bone insertion member (100) to downwardly move along the inner space and to induce opening of the lower part of the alveolar bone insertion member (100) into multiple parts； and a connection member (400) whose one side is joined to the opening of the alveolar bone insertion member (100) to close the opening, and whose the other side is joined to an artificial tooth (500). In addition, the dental implant may be made of pure gold； enables a precise secure binding between the implant and the alveolar bone without being much influenced by the shape of a space drilled in the alveolar bone； and serves to enhance tight binding strength. In addition, the dental implant according to the present invention allows a precise control over a transplantation height of the dental implant so as to match the height at which a gum is formed； and in particular, can significantly prevent the problem of crack formation of the implant, which has been particularly problematic in the prior art； and at the same time, can significantly reduce adverse effects due to an implant surgery such as development of inflammation and nerve irritation.본 발명에 따른 치아 임플란트는 상부에 개방부가 형성되고 내부에 공간이 형성되며 상부에서 하부로 갈수록 내부공간이 작아지며, 하부에는 하부가 여러 갈래로 갈라질 수 있도록 절개부 (110)가 형성되고, 치조골에 삽입되는 치조골삽입구 (100)； 상기 치조골삽입구 (100)의 내부공간에 삽입되어 상기 내부공간을 따라 하부로 이동되면서 치조골삽입구 (100)의 하부가 여러 갈래로 갈라져 개방될 수 있도록 유도하는 개방유도구 (200)； 및 일 측은 상기 치조골삽입구 (100)의 개방부에 결합되어 상기 개방부를 폐쇄시키며, 타 측은 인공치아 (500)와 결합되는 연결구 (400)；를 포함하며 순금으로
