A dental implant is designed to be fixed into an undercut socket in the bone. For example, an undercut socket may be drilled into the jawbone. Optionally, the undercut is produced using a T-slot milling bit. Optionally, the implant includes retractable protrusions. For example, the implant is inserted into the socket with the protrusions retracted and/or the protrusions are extended when they reach the undercut. For example, the protrusions may be biased outward (e.g., by a spring) and/or there may be tool (e.g., a screw that is inserted into the implant after it reaches the undercut) which causes the protrusions to extend.

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.

The present invention relates to a dental implant having an anchoring system consisting of foldable fins actuated by an insertion screw; the dental implant is characterised by the following components: an implant body that comprises an implant-abutment connection zone, an externally threaded zone, at least one pair of exit openings and an internally threaded zone; an anchoring means comprising at least one pair of foldable fins and a top opening; an insertion screw comprising a head with an internal hexagonal socket, a stem and a screw thread; when the insertion screw is screwed into the top opening of the anchoring means, it pushes the anchoring means down into the implant body and causes the foldable fins to extend outwards through the exit openings.

A medical that is implantable into a human or animal body or being an augmentation device for strengthening human or animal hard tissue for subsequent implantation of a separate implant. The device includes a sheath element suitable of being brought into contact, during a surgical operation, with live hard tissue and/or with hard tissue replacement material. The sheath element has a, for example, generally elongate shape and a longitudinal bore defining a longitudinal opening reaching from a proximal end of the sheath element into a distal direction, and a plurality of holes in a wall of the opening. Further, the device includes a liquefiable element that is insertable or inserted in the longitudinal opening and at least partly liquefiable by the impact of energy impinging from the proximal side.

The present invention relates to an implant system for implantation into a zygomatic bone. The implant system forms a dental substructure and comprises an apical system end and a coronal system end. The coronal system end includes a coronal superstructure interface along a superstructure interface axis for supporting a dental superstructure, wherein the implant system has a length in a range of 30 mm to 60 mm and includes at least two components. The invention further relates to a zygoma implant extension to be connected to an implant for implantation into a zygomatic bone, a handling tool and to a method for implanting a zygoma implant of a zygoma implant system as well as to a method for a partial implant system revision

An osseous anchoring implant with optimized expansion, having a tubular body and a rod whose external profile of the rod and internal profile of the tubular body are complementary. The implant being expandable between a rest configuration in which an abutment mechanism interlocks the tubular body and the rod thanks to the reversal of their two respective screw pitches, so that they provide in an expanded configuration radially: a proximal bearing point, a distal bearing point, a “central” bearing point located between these two bearing points, formed by the cooperation between the outer diameter of the rod and the inner diameter of the tubular body which induce an outer diameter of the tubular body at the “central” level greater than the outer diameter of the tubular body at the proximal bearing point.
