Abstract: An extension piece (2) for a dental implant (1) has a head part (20) which serves as a basis for a retention element (7). The extension piece (2) can be screwed in the dental implant (1) with a threaded stem (29). The extension piece (2) is provided with a reference surface (24) via which the position of the extension piece (2) in the circumferential direction can be transferred to a transfer aid (4) having a transfer surface (42) shaped to complement the reference surface (24). The position of the extension piece (2) is transferred via the transfer aid (4) into an impression (93). The extension piece (2) is then provided with a manipulation implant (5) and is repositioned in the impression (93). From this, a working model (M) is formed in which the desired shape of the extension piece (2) can be defined. The extension piece (2) which has been machined to the desired shape is then screwed into the implant (1) with the same torque as is used for taking the impression.
Abstract: Package system (2) for a powdery, granular, paste-like or liquid sterile product comprising a platic outer tray (4) and a plastic inner tray (6). The inner tray (6) is to be sealed with a first plastic cover to form a sterile receptacle for the sterile product. The outer tray (4) is to be sealed with a second plastic cover to form a sterile receptacle for the inner tray (6). The inner tray (6) has a spout (40) for the application of the sterile product.
Abstract: The shank (12) of a disposable rotary cutting tool (10) comprises a pipe section (16) cut from a drawn metal pipe. The tool head (14) is formed from a cut-out (18a, 18b) of a drawn metal sheet or a section of a metal tube by non-cutting machining. The pipe section (16) and the tool head (14) are advantageously attached by force fitting.

Abstract: A dental implant is disclosed comprising an anchoring part for anchoring within a bone and comprising a mounting part for receiving a prosthetic build-up construction, wherein the anchoring part and the mounting part are configured integrally of a material comprising zirconia, wherein at least the anchoring part is treated at its outer surface at least partially by a subtractive, removing process, such as by sand blasting or is provided with a coating which facilitates an ossification.
Abstract: The present invention relates to a binary single phase titanium-zirconium alloy suitable for the production of surgical implants. The alloy includes a zirconium content of less than 25% but more than 5% by weight, and 0.1% to 0.3% by weight of oxygen as a strength enhancing additive, and not more than 1% by weight of other strength enhancing additives and technical impurities.
Abstract: The present invention relates to a new and improved low-concentration formulation of an active enamel substance, such as an enamel matrix, enamel matrix derivative and/or an enamel matrix protein, intended to be used as therapeutic, as propylacetic and/or as cosmetic agent. In the present invention, said active enamel substance is incorporated into a polymeric matrix, which is either suitable for cellular in-growth, or cell-occlusive. The active enamel substance can be incorporated into the polymeric matrix so that it is released by degradation of the polymeric matrix, by enzymatic action and/or by diffusion. Comprised in the invention is thus in particular a new pharmaceutical and/or cosmetic formulation of an active enamel substance at a lower total concentration within the formulation, wherein a spatial and/or selective regulation of release of said active enamel substance permits a greater percentage of the active enamel substance to be released at the time of appropriate cellular activity.

Abstract: A process for providing a topography to the surface of a dental implant, said surface being made of a ceramic material. At least a part of the surface of the dental implant is etched with an etching solution comprising hydrofluoric acid at a temperature of at least 70° C. Thereby, discrete grains or agglomerates of grains are removed from the ceramic material.
