An augmentation method is provided, wherein a thermoplastic augmentation element is subject to mechanical energy impact and mechanical pressure by a tool so that augmentation material of the augmentation element is liquefied and pressed into hard tissue to augment the hard tissue, wherein in at least one axial depth, the augmentation element is segmented as a function of the circumferential angle so that at this axial depth the circumferential wall of the initial opening in first regions is in contact with the augmentation element and in second regions is not in contact with the augmentation element.

The invention relates to a screw and corresponding screw driver for driving the screw into a dental implant at an angle from the longitudinal axis of the implant. The screw has a polygonal interface and the screw driver has a matching interface for driving the screw to rotate.

A method for providing a guided relative movement of a first object and a second object includes obtaining the first object; obtaining the second object and a 3D model of the second object, and deriving from the 3D model a first preferred relative arrangement between the first and second objects; obtaining a pre-process plan describing a preferred path for the relative movement of the first and second objects towards the first preferred relative arrangement; performing a movement procedure that includes 3D scanning at least a region of said second object using the 3D scanner and determining a present relative arrangement of the first and second objects from a result of the 3D scanning; calculating information for correcting in real-time for deviation in the relative movement from the preferred path; and providing a relative movement of the first and second objects towards the first preferred relative arrangement.

Drill bits for cutting bones adjacent to soft tissue are disclosed. According to one example, the drill bit includes a working portion having a top cutting surface including a first top cutting surface and a second top cutting surface. The second stop cutting surface has an angle with respect to a line perpendicular to the longitudinal axis of the drill bit that is less than an angle with respect to a line perpendicular to the longitudinal axis of the drill bit of the first top cutting surface.

The present invention relates to dental cylindered pins suitable for controlling the amount of jaw-bone to be removed prior to placement of a dental implant into a drilled implant socket, for enabling easy and simple positioning of a dental implant, as well as to kits comprising said pins, and method of use.

A threaded dental implant to be screwed into a jawbone for supporting at least one abutment and/or a dental superstructure, and having a socket arrangement with a first section and a second section with respective geometrical profiles around a longitudinal center axis of the implant. The first section cooperates with the abutment for securing the abutment in a determined position in the implant. The second section cooperates with an insertion tool for screwing the implant into the jawbone. The first section includes an annular coronal contact surface on top of an opening centric at a coronal end of the implant, followed in an apical direction by a first tapered section having a diameter decreasing in the apical direction, by a first cylindrical section, by first anti-rotational elements and by a threaded section.

The present invention provides a kit for use for the implantation of a dental implant, comprising an implant guide comprising a proximal end and a distal end, wherein the distal end is configured to be detachably attached to a dental implant, said implant guide comprising a cylindrical body, wherein the cylindrical body comprises a cylindrical outer surface and a circumferential groove in the outer surface, and a template configured to be arranged at a predetermined location with respect to a jaw, wherein the template comprises at least one implantation channel to guide the cylindrical body of the implant guide in a desired implantation direction during implantation of a dental implant in the jaw, and a stop surface at an end of the implantation channel.

The kit comprises a stop element comprising a first part and a second part, wherein the first part and the second part are configured to be movable between a first state, in which the first part and the second part are spaced at a first distance, and a second state, in which the first part and the second part are spaced at a second distance, wherein the first distance is smaller than the second distance, and wherein the first and second parts are biased to the first state, wherein the second distance is the same or larger than a distance between diametrically opposite sides of the outer surface of the implant guide, such that, before implantation, the first part and the second part can be arranged, in the second state, on diametrically opposite sides of the outer surface, and that during movement in the implantation direction of the dental implant into the jaw, the stop surface of the implantation channel will push the stop element towards the groove until the groove will allow the first and second part to move towards the first state and the stop element will be caught by the groove, therewith blocking further movement of the implant guide in the implantation direction.

One aspect of the invention concerns an overdenture retention implant (10) comprising an externally threaded implant body (12) to be screwed into a hole formed in a jawbone (70) and an implant end structure (14) at a proximal end of the implant body. The implant end structure includes a tool engagement portion (14.1) that can be engaged by an implant installation apparatus operable to rotate the implant to screw the body into the hole, and a threaded boss (14.2) to be engaged in threaded manner by an overdenture retention cap (100) configured for attachment of an overdenture. The tool engagement portion and boss have a common, central axis (22) which intersects the central axis (20) of the implant body at an acute angle (24). Other aspects of the invention concern the combination of the implant (10) and installation apparatus and the installation apparatus itself.

A dental implant for securing an abutment to a jawbone, the implant including a tapered body having a longitudinal axis, the body including a coronal end and an apical end, the coronal end including an inclined coronal surface. A first bore receives a base portion of the abutment, the first bore extending downwardly from the coronal surface and parallel to the longitudinal axis of the body. A second bore with a footprint larger than the first bore includes a flange adapted to be abutted by a top portion of the abutment, the diameter of the second bore being off-axis and larger than that of the first bore.

A milling cutter and guide piece, the milling cutter including an elongate shaft extending along a longitudinal axis and a distal end portion having a milling part including at least one circumferentially disposed cutting edge for removing bone tissue, the guide piece having a fixation element, for releasably fixing the guide piece to a support structure, and a longitudinal axis, wherein one of the guide piece and the distal end of the milling cutter includes a head having a central axis coaxial to the longitudinal axis of the one of the guide piece and the distal end of the milling cutter, and the other of the guide piece and distal end of the milling cutter includes a inner cavity extending along a central axis coaxial to the longitudinal axis of the other of the guide piece and the distal end of the milling cutter.
