The metal porous body according to one aspect of the present invention has a framework of a three-dimensional network structure. The framework is hollow inside and is formed of a metal film, and the metal film contains titanium metal or titanium alloy as the main component.

A dental implant includes an anchoring region (12) for anchoring in a bone, which preferably includes a thread (14) for screwing in the bone, and a fastening region (22) for attaching a supra-construction, wherein an abutment region (16) adjoins the anchoring region (12), the abutment region (16) having a guide structure with a plurality of outwardly projecting ridges (18) provided thereon, and preferably, grooves (20) being formed between the ridges (20). The guide structure of the anchoring region (12) allows a better osseointegration and counteracts peri-implant bone loss.

A fixture for insertion into a bore hole arranged in bone tissue is provided. The fixture has a threaded leading portion provided with at least one cutting edge for creating a female thread in the bone tissue, and a threaded trailing portion following the leading portion in the created female thread. Compared to the geometry of a thread peak of said cutting edge of the leading portion, a thread peak of the trailing portion is displaced or overdimensioned in at least one of the coronal and apical directions of the fixture so that a strain is provided to the bone when said displaced or overdimensioned thread peak engages with the created female thread. A fixture set for creating a strain is also provided, the set comprising a fixture and a separate thread maker.

A method for securing a dental implant within a dental bone cavity is disclosed. The method may include inserting a dental wedge into the dental bone cavity and allowing bone tissues to grow toward and at least partially surround the dental wedge. Dental implantation systems for implementing the method are also disclosed. The system can include a dental wedge adapted to be inserted into a dental bone cavity.

An implant fixture is disclosed. The implant fixture contains an elongated shaft section, and a head section, wherein the head section contains at least one concave area for bone growth therein.

An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.

A fastener for embedment in bone includes a chevron-shaped thread pattern having a first radial superior surface at an angle beta on a blank relative to a longitudinally extending axis of the fastener, a second radial superior surface at an angle alpha inboard to the first radial superior surface and relative to the longitudinally extending axis such that the two superior surfaces form a V-shape geometry. The fastener further includes a flank surface underlying the second radial superior surface at an angle gamma, the angle gamma defining an angle with the longitudinally extending axis that is 90, a relief surface underlying the first radial superior surface such that the flank surface and the relief surface form a V-shape geometry, and a radially-outermost surface adjacent to the relief surface and defining a major diameter of the thread pattern, the radially-outermost surface being parallel to the longitudinally extending axis of the fastener.

A dental implant including an implant body having a top surface, and at least one non-annular cutaway portion longitudinally extending downwardly from the top surface along one side of the body and outwardly to the periphery, and a method for making the implant. The implant body preferably includes a body portion and a head portion integrally formed with the body portion, the body portion has a periphery and the head portion has a non-circular periphery, and the periphery of the head portion is smaller than the periphery of the body portion.

Custom dental prosthesis or implants each individually designed and manufactured to replace nonfunctional natural teeth positioned in a jawbone of a specific pre-identified patient are provided. An example dental prosthesis/implant includes a dental implant body having a prosthesis interface formed therein to receive an occlusal-facing dental prosthesis component. The prosthesis interface has a custom three-dimensional surface shape positioned and formed to create a form locking fit with respect to the occlusal-facing dental prosthesis component when positioned thereon.

A dental implant system includes an anchoring part of a ceramic material for anchoring in bone tissue, an abutment of ceramic material, and an abutment screw. The anchoring part has a recess that is open towards a coronal end for engagement of a fastening post of the abutment. The abutment has an opening that is continuous in the axial direction and into which the abutment screw can be inserted. The abutment screw is configured, for a fastening of the abutment to the anchoring part, to engage into an inner thread that is formed on the anchoring part in the recess or is present on an insert element that is inserted into the recess. The abutment screw has a screw head, and a shoulder, which is formed coronally and which together with the screw head forms a stop on inserting the screw into the opening, is present in the opening.
