Abstract: The present invention relates to a method of providing a patient-specific dental fixture-mating arrangement, such as a dental abutment. According to the method, an arrangement is provided which can only be arranged in one rotational position with respect to a fixture in the jawbone of a patient. The arrangement is designed based on the orientation and inclination of the fixture relative to the jawbone. The invention also relates to a dental implant arrangement, comprising a dental fixture and a final dental restoration having mating indexing means.

Abstract: The present invention relates to a fixture, such as a dental fixture, for insertion into a bore hole arranged in bone tissue, comprising a threaded leading portion and a threaded trailing portion located coronally of the leading portion. By a widened threading at the trailing portion, the bone tissue is subjected to a static strain beyond the yield strain of the bone tissue. The invention also relates to a fixture set and to a method of insertion of a fixture into a bore hole arranged in bone tissue.

Abstract: The present invention relates to a dental implant assembly, comprising a fixture for insertion into a jawbone which is provided with a first thread with a first thread start, and a dental component which is not axially symmetrical and which is provided at its apical end with a second thread with a second thread start having a rotational position which is known in relation to the asymmetrical shape of the dental component for engagement with the first thread.

Abstract: The present invention relates to a dental component, which can only be connected in one indexing position in one type of dental fixture, but in any one of a plurality of indexing positions with another type of dental fixture. The dental component is provided with primary projections which are not completely evenly distributed around the circumference of an engagement portion of the dental component. The invention also relates to a dental fixture, a dental implant assembly and a dental implant system.

Abstract: The present invention relates to a dental fixture for insertion into a jawbone, said fixture comprising a holding portion which is arranged and configured for holding an engagement portion of a dental component, the holding portion being provided with an indexing section, wherein the shape of the mating contour of the indexing section in a first plane differ from the shape of the mating contour of the indexing section in a second plane being taken at a different height as seen in the apical-coronal extension of said fixture, and wherein the shapes of the mating contours of the indexing section at said first and second planes together allow a received dental component to be positioned in only one or two positions in relation to the fixture. The present invention also relates to a corresponding dental component and to dental implant assemblies.

Abstract: The present invention relates to a fixture for insertion into a human bone. The fixture comprises a core from which a surface structure projects. At least one channel is provided in the surface of the surface structure and has an extension in a direction towards the top of the surface structure. The depth of the channel is smaller than the height of the surface structure.
