A dental implant assembly comprising an elongated inner body substantially resembling a tooth root (1-1) and an outer member for securing to a bone of a patient (1-2) having a heterogeneous porous structure adapted to provide bone growth, the inner body and the outer fixation member being formed in one piece, the fastening element being movable between a stored passive position and an extended active position (1-2).

A false tooth implanting device with widening effect, including a main implant body, a lower block, and a vertical screw which is threaded to the lower block after passing through the main implant body; a small vertical securing screw is threaded to a screw hole provided on the vertical screw; an installation direction indicator is provided on a top surface of the device such that dentist can quickly and conveniently knows a direction which the widening effect will achieve, thus enhancing installation accuracy, avoiding suffering to the alveolar bone due to widening effect towards an incorrect direction, and thereby ensuring safety and convenience of the use of the device and the efficiency of false tooth implantation

A dental implant for supporting periodontal tissue and the supporting bone is provided. The dental implant includes an implant member with inner canal for insertion into a periodontal bone socket, and an anchoring assembly. The anchoring assembly includes a first fastening element and radially equidistant cylindrical members. The first fastening element engages the implant member within the hollow axial cavity. The root section includes through-holes for radially and forcibly sliding the cylindrical members through them. When the first fastening element apically advances within the hollow axial cavity, the cylindrical members generate an anchoring force to anchor the dental implant.

An osseous anchoring implant with cortical stabilization, including an expandable sleeve having a first threading inside and a second threading outside, a screw having an external profile complementary to the internal profile of said expandable sleeve and an external threading with a reverse screw pitch of the second threading. The implant switching from a folded rest position to a deployed position by the actuation of said reversed threadings, causing the penetration of the screw into the expandable sleeve and generating the radial expansion of said expandable sleeve by deformation on a distal portion. In the deployed position, the expandable sleeve has a frustoconical shape. The proximal portion of the screw includes an outer osseous anchoring threading and a frustoconical portion whose flaring is reversed relative to that of the expandable sleeve in the deployed position.
