Abstract: Dental implant of the type formed by a single body, having an implant section intended for introduction into the maxillary bone and provided with a self-tapping screw, and a receiving section that comprises a troncoconical surface intended to receive directly a temporary or permanent dental prosthesis, the said implant also having an axial orifice with a thread for receiving a retaining screw, as well as a polygonal prismatic section intended for the tightening of the implant for its implantation in the bone, characterised in that the conical section is immediately adjacent to the implant section, without the intermediation of the polygonal prismatic section.

Abstract: Non-traumatic expansion devices for the bone for receiving affixing means for dental prosthetics, each expansion device being formed by a one-piece component (1) having an upper base (11) formed as a prismatic screw head. A center body (3) has milled generating lines extending in axial direction. A first transition area (5) is disposed between the center body (3) and the upper base (11). A threaded end (9) has a shape of an elongated cone and a second transition area (7) has a conical shape tapering toward the threaded end (9). Each expansion device has a different thickness and length on the threaded end (9) depending on the type of required expansion. The expansion device has the function of a screw for the purposes of drilling the bone and keeping the bone mass whole.
