Abstract: Provided is a dental implant assembly for insertion into the jawbone of a patient. The dental implant assembly is used to hold a dental prosthesis and includes a main body which connects the dental implant to the alveolar bone, an abutment and a connecting element. The main body and the abutment each have a coupling region. Together, these coupling regions form an interface. One of the coupling regions is concave and the other convex, and portions of the coupling regions are congruently shaped. The abutment and the main body are connected by means of a connecting element.

Abstract: The invention relates to the use of ceramic parts that at least partly consist of a ceramic foam in the field of medical technology.

Abstract: The invention relates to thermally sprayed ceramic layers and a method for the production thereof.

Abstract: The invention relates to a cutting broaching tool (1) for intraoperatively obtaining bone material from a patient, comprising a main part (3) which rotates about a rotational axis (2) for securing on a rotating tool support and comprising at least one blade (4) which is rigidly connected to the main part (3). The aim of the invention is to prevent the tissue from reacting when using the broaching tool and thus prevent an increased risk of infection, to prevent a thermal load on the bone, to receive the bone material in the interior of the broaching tool, and to discharge the bone material to an external device. This is achieved in that the main part (3) has a cylindrical shape, is hollow, and surrounds a first cavity (5). The blade (4) or all the blades (4) are formed integrally with the main part (3), extend in the direction of the rotational axis (2) of the main part (3) at a distance from an end face (6) of the main part (3), and surround a second cavity (7).

Abstract: A spacer comprised of individual components as joint replacement in the arthroplasty of shoulder, knee, and hip for the temporary surgical care of infections in the joint. The problems addressed by the invention are those of avoiding an adhesion of the bone to the spacer and a release of wear products, achieving that the patient does substantially not experience any mobility restriction, and keeping the wear and tear of the spacer as little as possible. These problems are solved in that at least one component of the spacer is made of a ceramic material, of a plurality of ceramic materials, or of a non-ceramic material having a ceramic coating.
