Abstract: 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.

Abstract: 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.

Abstract: An osseous anchoring implant with facilitated extraction having: an expandable sleeve extending between a proximal portion, and a distal portion, defining a longitudinal axis, a screw extending between a proximal portion and a distal portion on an axis collinear with the axis, having an external profile complementary to the internal profile of said expandable sleeve, the screw comprising at least one distance marker to visualize the moment when the screwing of the screw in the expandable sleeve must be carried out in the opposite direction to the screwing of the expandable sleeve. The implant switches from a folded rest position to a deployed position by the penetration of the screw in the expandable sleeve. The distal portion including self-tapping notches. The distal portion includes a self-milling head.

Abstract: The invention relates to an endosseous implant capable of being implanted into osseous tissue. The implant comprises an attachment device (3), comprising: a so-called gripping portion (31) for gripping the osseous tissue, a so-called expansion portion (32), said two portions being mobile in relation to each other, engaging mechanical connection means (33, 33a, 33b), located on the gripping portion (31) on the one hand and on the expansion portion (32) on the other hand, such that the relative mobility of the two portions has at least one degree of freedom, and such that a relative movement of said two portions causes an extension of the gripping portion, said extension causing the gripping portion to engage with the osseous tissue. The endosseous implant can in particular be used in the dental field.
