摘要： A spacing member for a securing element (fixture) permanently anchored in the jawbone. The spacing member comprises a substantially sleeve-shaped spacing element to be fitted on the securing element and a separate spacing screw. The spacing screw has an elongate, unthreaded middle portion and a threaded portion at its tip for engaging with an internally threaded bore in an upper part of the securing element. The sleeve-shaped spacing element includes a passage extending longitudinally therethrough for receiving the spacing screw. The passage has an internally threaded portion for engaging with the spacing screw, so that the spacing screw, after it has been threaded through the threaded portion, is joined together with the spacing element, and a recess in an upper part of the passage. The recess has a non-circular geometry for facilitating application of a counter-holding instrument in order to prevent the tightening force from being transmitted down into the securing element when the sleeve-shaped spacing element is fitted on the securing element.

摘要： The disclosure relates to an apparatus for the fixation of a single-tooth restoration to an implant in the form of an anchorage element (fixture) permanently anchored in the maxillary, comprising a substantially tubular spacer (4) which is anchored to the anchorage element by means of a spacer screw (5) provided with an externally threaded portion (23) which engages in an internally threaded recess (7) in the upper region of the fixture. The spacer screw (5) is provided with an unthreaded waist (25) whose length exceeds the thread diameter of the spacer screw, and has a screw head (20) of comparatively slight diameter and with a planar or gently conical shoulder which cooperates with a corresponding annular shoulder (19) in the tubular spacer (4). The apparatus is mounted in place by means of a double screwdriver whose one part fits the internal counter-abutment in the spacer sleeve (4) and whose other part is caused to engage with the driver slot (24) of the screw head. In the mounting operation, equal, but counter-directed torques are applied to both parts of the screwdriver so that the implant will remain unloaded during the mounting operation proper.

摘要： A device for transferring the direction and position of a dental implant or its extension element, such as a spacer element, to a work model, includes a base part and an elongate upper part projecting from the base part. The device is made of an elastic material so that clamp fitting is obtained between the base part and the implant or its extension element. The upper part has a geometry which provides for retention in the surrounding impression compound and has break notches so that it can easily be shortened.

摘要： A device made of a tissue-compatible material is intended to temporarily cover a spacer of a dental implant during a period of incorporation of the dental implant, preferably in a single-tooth replacement. The base section of the device is designed in such a way that it guides the healing of the mucous membrane to assume a contour such that securing of the final crown is facilitated, and a certain possibility of controlling the seam between the final crown and the spacer is afforded. The device is preferably made of an elastic material for good clamp fitting on the spacer, as a result of which the use of paste, dental cement or the like is eliminated.

摘要： An angulated spacer element adapted is at its one end for attachment to a fixture having a threaded aperture and implanted in the jaw bone, and to support a dental prosthesis at the other end. The spacer element, which is a unitary member, has a first portion with an end surface thereof permitting abutting engagement with the protruding end of the implanted fixture. The first portion also has a through bore aligned with the threaded aperture in the fixture and defining an internal ledge to enable a screw to pass through the bore, abut the ledge and threadably engage the threaded aperture in the fixture. The first portion is adapted for locking the spacer element in a selectable one of a plurality of rotational, fixed positions in relation to the protruding portion of the fixture. The unitary spacer element also includes a second portion for supporting the dental prosthesis on the spacer element, the second portion forming an acute angle with respect to the through bore of the first portion.

摘要： An impression coping is provided for taking an impression of an implant installed in a patient's mouth. The impression coping comprises an engagement portion, a cover and an impression portion. The engagement portion is adapted to be inserted within an internal cavity of the implant. The engagement portion has a plurality of axially extending protrusions positioned around the periphery for engaging corresponding channels within the internal cavity of the implant. The engagement shaft is thus configured to register the internal orientation of the implant within a patient's jaw. The impression portion of the coping includes one or more embedment features adapted to be embedded in a dental impression material for taking a dental impression thereof.

摘要： An implant is provided with an upper portion in which an internal socket extends. The implant (12) can be tightened by means of a turning instrument (11) which has first lateral surfaces (14) that can cooperate with corresponding second lateral surfaces (15) in the internal socket. One or more of the first and/or second lateral surfaces is/are arranged completely or partially with friction-enhancing means (16). The implant and the tool are arranged with interacting parts which extend beyond the first and second lateral surfaces and completely or substantially take up bending moments (M, M′) which act in or on said portion or are directed toward said portion and occur in the event of skewing, or a tendency toward skewing, between the implant and the tool. The arrangement counteracts mechanical stresses in said portion, the latter being able to retain its original shape even in the case of implants with small dimensions.

摘要： The invention relates to a distance member (1) for a tooth implant anchored in the jaw, which distance member comprises, on the one hand, a sleeve-shaped element (5) which is designed to connect with the shoulder part of the securing element (fixture) (2) of the tooth implant and, on the other hand, a distance screw (7) provided with an externally threaded part (8) for engaging in a bore (9) in the upper part of the fixture for anchoring the sleeve-shaped distance element (5) on the fixture (2). The distance screw (7) is provided with an upper bore (25) for securing of a cap (4) embedded in the prosthesis construction. The upper part of the distance member is designed to be accommodated within a conical, upwardly narrowing delimiting surface defined by the said cap (4). The upper part (17) of the sleeve-shaped element has a conical peripheral surface (18) with an engagement part (14) designed to cooperate with a tubular counterstay (29) in a fitting tool, and the distance screw (7) also has a conical peripheral surface which forms an extensions of the conical upper part (17) of the sleeve-shaped element, and which has an external engagement part designed to cooperate with a second part, a tightener (27) in the fitting tool. The design of the distance member permits a low distance height and facilitates handling.
