The invention relates to a fastening device for an implant that is elastically deformable by stress, the length of the device in the unstressed state being less than that of the device in the stressed state, and the diameter of the device in the unstressed state being greater than that of the device in the stressed state, and to a kit comprising it.

An apparatus may include an elongated hollow body with a plurality of skirts on one end of the elongated hollow body. An exterior of the elongated hollow body may have a plurality of fins. At least some of the plurality of fins may have a different diameter and/or placement along a length of the elongated hollow body. The elongated hollow body may be configured to receive a screw. The screw may be configured to expand the plurality of skirts upon insertion into an interior of the elongated hollow body. The plurality of fins may be configured to secure the apparatus when the apparatus is placed within a bore. The plurality of fins may secure the apparatus at least by engaging the bore.

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.

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.

A false tooth implanting device, having an expandable implant body, a lower protruding block at a recess of a lower portion of the implant body, a vertical screw, and a lateral screw; the recess has a first slanted engaging surface; an upper portion of the expandable implant body is provided with a vertical hole and a first portion of a vertical screw hole; the lower protruding block is provided with a second slanted engaging surface in contact with the first slanted engaging surface and a second portion of the vertical screw hole; the vertical screw passes through the vertical screw hole; the upper portion of the expandable implant body is provided with an expansion crevice and a lateral screw hole; when the lateral screw is screwed into the lateral screw hole, the upper portion of the expandable implant body is widened by expanding away from the expansion crevice.

An expendable bone implant has a first member with a coronal end portion configured for supporting a prosthesis. A second member is at least partially porous, engages the first member, and is configured to expand outwardly upon a longitudinal force being applied to at least one of the first and second members. This anchors the implant in bone before mastication forces are applied to the implant.

A dental device comprises: a dental implant comprising a core enveloped by an expandable anchor comprising a plurality of joined segments. Prior to insertion of the core into the expandable anchor a carrier apically displaces within the expandable anchor, generating an expansion force causing the plurality of joined segments to be displaced linearly away from the central axis of the implant where the coronal and apical ends of each joined segment are displaced in parallel paths normal to the central axis of the implant. The core inserts into the expandable anchor to lock the plurality of joined segments in their expanded configuration. At least a first rail on the core is received by a corresponding expandable anchor slot to align the core and expandable anchor and at least a first core and expandable locking lodge engage to lock the core into the expandable anchor.

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.

An osseous anchoring implant with cortical stabilization. The implant having: 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 threading, causing the penetration of the screw into the expandable sleeve and generating the radial expansion of the 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.

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.
