Abstract: An instrument holder includes a substantially tubular base body which includes a grip portion and an instrument holding portion. The base body includes a through recess extending over an entire length thereof, and the instrument holding portion includes a front-sided insertion opening designed for insertion of an instrument.

Abstract: A medical membrane, in particular a dental membrane for regeneration and/or inducing of tissue, in particular of periodontal tissue and for use in direct contact with bone tissue or connective tissue along with a tooth implant.

Abstract: A dental handpiece to which various tools forming a tool set can be coupled, and more precisely a handpiece coupling, which can be driven by a drive in the dental handpiece at least for an axial oscillating motion The coupling is constituted for a connection of the tools by insertion and securing, and more precisely with a conically tapering opening, into which an adapted coupling section of the tools that tapers in the shape of a truncated cone can be introduced and secured in a suitable manner.

Abstract: A tooth implant which has an implant body, which is, preferably embodied as a single piece with a support which is anchored in the bone tissue, in addition to a journal which is secured to one end of the implant body which is used to secure a constructional component. The journal has several groove-like recesses which are oriented, respectively, in the longitudinal direction thereof and, are distributed on the periphery of the journal and projections are arranged therebetween.

Abstract: The invention relates to a tooth implant having an implant body with at least one intraosseous region that can be anchored in the bone, a penetration region for penetrating the soft tissue, and a coronal region with retention pegs, the regions being adjacent in the longitudinal axis of the implant body. The intraosseous region is made of at least three partial regions which are also adjacent in the direction of the longitudinal axis and have different threads.

Abstract: A trepan drill that comprises a shaft that includes a clamping portion, and a head that comprises a substantially cylinder barrel shaped core bit and a distal end. The distal end includes a first tooth, a second tooth, and a third tooth that each respectively has a cutting edge. The teeth each have different axial teeth heights and are arranged alternatingly in a circumferential direction.

Abstract: A bone graft drill includes a shaft with a shaft axis, and a head with a rear side connected to the shaft and being shaped substantially conical at a front portion. A guiding tip is formed at a front end of the head, and a chipping recess is also formed in the head with an axis being inclined diagonally with respect to the shaft axis. The chipping recess has an edge constituting at least one cutting edge and an opening toward the rear side of the head.

Abstract: The invention relates to a method for establishing a releasable connection between a tool connection or coupling piece, which is formed on a dental handpiece, and the tool shank of a dental hand instrument. In order to connect a journal-like fastening section, which tapers toward a free end, on one of the elements to be connected, is inserted into an opening while matching the same, which is adapted to this section, on the other of the elements to be connected.

Abstract: The invention relates to a novel embodiment of a dental implant comprising a root section or root shaft that can be anchored within a jaw preferably by screwing, and a cap which is made of a solid material and can be fixed onto a coronal area of the shaft by means of an adhesive bond.

Abstract: The invention relates to a tooth implant including a threaded enossal region 1, a middle region 2 and a coronal region 3, characterized in that the enossal region 1 includes different threaded sections.

Abstract: A supporting mechanical connecting element of metal or the like high-strength material, preferably for the medical and dental field, is formed so that the connecting element and/or the receiving element is coated with a hydrolysis-stable bond-assisting layer undergoing a hydrolysis-stable chemical or physical-chemical bond with the material of the receiving element. In order to improve the mechanical retention the connecting element being used for anchoring has a cylindrical shaft, a circular portion conically tapering towards the free end and a circular, in cross section U-shaped recess extending from the free end inwardly, whereby this form is chosen so that it results in a tension reduction.

Abstract: A process and apparatus for three-dimensional determination of the relative movement between the upper and lower human jaws by affixing at least one reference element to each of the jaws, one of the reference elements having four spatially staggered reference marks and the other having at least three spatially staggered reference marks. The position of each reference marks is optically detected along at least two viewing axes. The relative movement of the jaws is then determined from the change in the mutual position of the reference marks.

Abstract: A dental retention pin preferably made of metal is provided with a closed, cylindrical coating of bond assisting material, and an additional layer of a plastics filling material in order to obtain a physical-chemical or a purely chemical bond between the retention pin and the filling structure for obtaining a substantially increased retention power compared with known metal pins, which merely result in a mechanical or mechanical-physical joint to the filling structure. The retention force will be increased by shrinking the bond assisting layer or the outermost plastics layer onto said bond assisting layer around the pin so that the layer spans itself around the pin in a ring-like manner. Furthermore, examples for the structure of a retention pin are described, which improve the handling and insertion of such retention pins by the dentist considerably.

Abstract: This invention refers to a finisher comprising a rotation-symmetrical, conical body with a plurality of cutting edges at the generated surface of this body as well a stem extending from the base of this body, the axis of which stem is coaxial with the axis of symmetry of the conical body. Alternatively, the invention refers to a dental grinding and/or polishing tool comprising of a rotation-symmetrical, conical body with a generated surface formed as a grinding or polishing surface as well a stem extending from the base.
