Abstract: 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).

Abstract: 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.

Abstract: The disclosure relates to a spacer for dental implants of a bio-compatible material. The spacer includes an inner sleeve-shaped spacer element (4) of titanium which is part of a screw connection between an anchorage element (fixture) (1) implanted in the maxillary beneath the gingiva, and a dental prosthesis construction whose joint surface (11) is located above the gingiva and which is disposed to absorb the loading of the screw connection. The spacer further includes an outer spacer sleeve (12) of porcelain or ceramics which wholly or partly encloses the inner sleeve-like spacer element (4). The ceramic or porcelain sleeve may, by grinding and coating with porcelain of different colors, by caused by visually approximate a dental cervix and gingiva and, thereby, not contrast with the natural dental cervix color and gingival color to the same extent as does the titanium material.

Abstract: 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.

Abstract: A holding device allows for tightening of a screw joint in a bone-anchored dental implant without imposing stress upon the tissue surrounding the implant. The device includes a first part which is rotationally locked in relation to the implant and a second part in the form of an arm which is rigidly connected to the first part, extends substantially perpendicularly thereto and is provided with a holding portion which interacts with the stationary part of the tightening tool to prevent undesirable rotary movements.

Abstract: 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.

Abstract: The invention relates to a package for sterile and contamination free storage and transport of artificial implants (2), comprising a hermetically sealed outer casing (3) preferably made of glass, and an inner capsule to hold the implant, made of the same material as the implant (2) itself. The inner capsule comprises an open sleeve (1) preferably tubular, closed at one end by the implant (2) itself, so that the part (2a) of the implant which is intended for tissue integration is sealed by the sleeve (1).
