Bone fusion dental implant of the type able to form an artificial dental root as a support for a fixed prosthesis composed of one or more dental crowns, said implant being inserted into the bone of the upper or lower jaw by drilling a hole at a suitable location and to which implant the surrounding bone tissue fuses permanently as it grows, said implant also having a substantially cylindrical shape, with a crown end (3) provided with means (11, 4) for connecting with a prosthetic reconstruction and an apical end (2) designed for insertion into the bone, said implant having an externally threaded section (6) extending from crown end (3) over no more than one-third of the entire length of the implant, and a s section (1) without an external thread extending from apical end (2) over no less than twothirds of said length. In the section (1) not threaded externally, the implant is coated with a bioactive material, preferably hydroxyapatite, and is surface-threaded to make it rough and/or porous.
