A dental implant includes an insert element of a titanium-based material inserted and soldered into a blind hole in an anchoring element of a ceramic material. An outer surface of the insert element has spacer members to center the insert element in the blind hole, with a uniform circumferential gap space relative to the anchoring element. The insert element is longer than the blind hole, so that a portion of the insert element protrudes outwardly beyond an end face of the anchoring element. The blind hole is partly filled with a glass solder suspension, and the insert element is inserted into the blind hole, whereby an excess amount of the glass solder is displaced out of the gap space onto the end face of the anchoring element and the protruding portion of the insert element. A thermal soldering process secures the insert element into the anchoring element. The protruding portion of the insert element and remaining excess solder is removed to form a planar surface.

A process of using a dental implant for performing an antral procedure. The dental implant comprising an implant body having a proximal portion, a distal portion and at least one internal passageway whereby fluid communication is provided between at least one proximal opening in said proximal portion and at least a first portion of an outside of a distal end of said distal portion via at least one distal opening at or near said distal end. The dental implant is configured for implantation in a position wherein said at least one distal opening being adjacent to or within the sinus cavity and said at least one proximal opening being adjacent to or within the oral cavity, whereby an oro-antral channel is provided allowing for surgically accessing the sinus cavity from the oral cavity via said at least one internal passageway in a minimally invasive manner.

The present invention relates to a medical device for freeing an implant from the bone of a patient to which the implant adheres to and to an implant for insertion into a bone of a patient, designed such that the implant is more homogenously heatable or coolable in a controlled way. Also provided is a method of removing an implant from a bone of a patient and a computer readable storage medium having recorded thereon a database structure.

Provided is a dental implant fixture. The dental implant fixture includes: a body portion having an outer wall on which a threaded portion to be placed in an alveolar bone is formed; an abutment contact and support portion formed on an inner wall of the body portion at an entrance side, to which an abutment is coupled and supported in contact therewith; and an internal connection part formed on the inner wall of the body portion in an area where the abutment contact and support portion ends in a direction in which the body portion is placed in the alveolar bone, and having a non-circular cross-sectional structure to allow a predetermined tool for rotational handling of the body portion to be optionally connected thereto.

The invention relates to a sleeve (1) for providing a dental implant (2) with a disinfectable surface (100b), wherein the sleeve (1) is configured to be attached to an end or coronal region (20) of a dental implant (2), wherein the sleeve (1) comprises a through hole (101) encompassed by the sleeve (2) which through hole (101) is adapted to receive said end region (20) of the dental implant (2), wherein said through hole (101) is delimited by an inside (100a) of the sleeve which faces said through hole (101), and wherein the sleeve (1) comprises an outside (100b) facing away from said inside (100a), which outside (100b) forms said disinfectable or sterilizable surface (100b). Further, the invention relates to an arrangement of the sleeve on a dental implant as well as to a method for arranging the sleeve on a dental implant.

An implant for implantation into bone tissue includes an elongated body having an outer surface. The outer surface hast least one thread. The thread makes a number of turns around the body of the implant and includes a root, a flank and a crest. The root and a segment of the flank have a roughened portion compared to the crest. A method of forming an implant having a threaded outer surface including a root, a flank, and a crest includes treating the threaded outer surface at only the root and a portion of the flank while the crest remains untreated.

Embodiments of the present invention provide an osseointegrative implant and related tools, components and fabrication techniques for surgical bone fixation and dental restoration purposes. In one embodiment an all-ceramic single-stage threaded or press-fit implant is provided having finely detailed surface features formed by ceramic injection molding and/or spark plasma sintering of a powder compact or green body comprising finely powdered zirconia. In another embodiment a two-stage threaded implant is provided having an exterior shell or body formed substantially entirely of ceramic and/or CNT-reinforced ceramic composite material. The implant may include one or more frictionally anisotropic bone-engaging surfaces. In another embodiment a densely sintered ceramic implant is provided wherein, prior to sintering, the porous debound green body is exposed to ions and/or particles of silver, gold, titanium, zirconia, YSZ, -tricalcium phosphate, hydroxyapatite, carbon, carbon nanotubes, and/or other particles which remain lodged in the implant surface after sintering. Optionally, at least the supragingival portions of an all-ceramic implant are configured to have high translucence in the visible light range. Optionally, at least the bone-engaging portions of an all-ceramic implant are coated with a fused layer of titanium oxide.

An orthopedic implant includes an internal fixation device. The internal fixation device includes: an exterior surface; a threaded section including a reservoir and at least one threaded section channel fluidly communicating the reservoir with the exterior surface, each threaded section channel having an interior diameter and a length which is greater than the interior diameter; a head including a head channel fluidly communicating the reservoir with an exterior surface of the head, a channel diameter of the head channel being respectively larger than a largest interior diameter of each threaded section channel, the channel diameter of the head channel being the same as a large interior diameter of the reservoir; and a continuously tapering inner surface between the head channel and the reservoir.
