Abstract
A fixture for insertion into a bore hole arranged in bone tissue is provided. The fixture has a threaded leading portion provided with at least one cutting edge for creating a female thread in the bone tissue, and a threaded trailing portion following the leading portion in the created female thread. Compared to the geometry of a thread peak of said cutting edge of the leading portion, a thread peak of the trailing portion is displaced or overdimensioned in at least one of the coronal and apical directions of the fixture so that a strain is provided to the bone when said displaced or overdimensioned thread peak engages with the created female thread. A fixture set for creating a strain is also provided, the set includes a fixture and a separate thread maker.
