The invention provides a dental implant, characterized by a cylindrically threaded shaft section with at least a double lead thread. One lead thread is micro carved, while the other lead thread is carved with teeth of any shape, for instance V-shaped, buttress-shaped or square-shaped. The dimension of teeth increases gradually from zero in the lower part of the said implant (with constant or cone diameter) to approximately 0.1-0.2 of the diameter of the micro carving from the upper part of the said body implant. The maximal diameter of the said implant equals approximately 1.2-1.4 of that of the lower part. Thereto the internal body is supplied by a lead thread in order to block the said implant and may further be used for attachment of the key to turn in the said implant. |
