The present invention relates to an implant fixture. According to the present invention, the implant fixture is inserted into osseous tissue comprising cortical bone and cancellous bone to form an artificial dental root and comprises: a body portion comprising one end and another end in which a cross-sectional area of the other end located in the direction to be inserted into the osseous tissue is smaller than that of said one end formed on the opposite side of the other end a screw portion comprising screw threads formed along the outer circumferential surface of the body portion so that the implant fixture is operated in the implantation rotation direction implanted in the osseous tissue a screw threads-fixing portion formed at the end of the body portion and comprising a fixing groove grooved from the screw threads to the body portion and a concave groove formed on the surface of the screw threads. According to the present invention, by using the implant fixture and having a rough surface, a binding force with osseous tissue is increased, thereby allowing a fixing force to be maintained regardless of shallow implantation. Therefore, the implant fixture can be implanted into osseous tissue and an implanted state can be firmly fixed even if bone grafting is omitted, and thus it is possible to improve the durability of an implant and reduce all procedures and time for implantation.La présente invention concerne une fixation dimplant. Selon la présente invention, la fixation dimplant sinsère dans un tissu osseux comprenant de los cortical et de los spongieux pour former une racine dentaire artificielle, ladite fixation comprenant : une partie corps, qui comprend une extrémité et une autre extrémité, une section de cette autre extrémité, qui se situe dans la direction dinsertion dans le tissu osseux, étant inférieure à celle de la première extrémité, formée à lopposé de cette autre extrémité une partie vis, qui comprend des filets formés le long de la surface circonf
