The invention is related to a dental implant for a final denture comprising a substantially cylindrical base body (10) to be inserted in a hole made in a jaw bone, an abutment (50) that can be inserted in a recess (16) in the base body (10) and that includes a geometrical closure section, a hole (60) for a retaining screw and a support head (58) for a dental prosthesis, and a fixing screw that can be installed into a blind hole of the base body (10) and that passes through the abutment. A section (20) of geometrical closure of the base body (10) has at least one main body geometrical closure element (26) acting in the circumferential direction, and a geometrical closure section (52) of the abutment (50) has at least one abutment geometrical closure element (54) mating the main body geometrical closure element (26), the sections (20, 52) of geometrical closure of the main body (10) and of the abutment (50) are mating each other in their shapes, which allows to insert the abutment (50) in the recess of the main body so that the respective elements of geometrical closure become interlocked with each other. Mating each other geometrical closure elements (22, 26 54, 66 28, 53 68) are designed as connections of male and female parts of the tongue-in-groove joint type by virtue of a part of the base body (10) or of the abutment (50) having a spline ridge (26 53) that extends in parallel to the longitudinal axis of the main body and comprises a pin (22) retained in a fixing recess (22) and interlocking with a respective recess (28 54) on the other part, being fixed to prevent spinning.Изобретение относится к зубному имплантату для постоянного зубного протеза, содержащему основное тело (10), выполненное, по существу, цилиндрическим для установки в выполненное в челюстной кости отверстие, абатмент (50), выполненный с возможностью установки в выемку (16) основного тела (10), содержащий участок геометрического замыкания, отверстие (60) для размещения фиксирующего винта и опорну
