Abstract The dental implantate comprises a dental insert with a blank hole made therein having an inner thread. An adjuster bolt is mounted in this blank hole which is encompassed by a remote disk resting against the front of the dental insert. On the remote disk is fixed a superstructure that is fastened to the adjuster bolt. The latter has a conical sector which is encircled by a sealing ring. Outside the dental insert protrudes an adjusting bushing and on it is screwed a remote disk on which rests the superstructure. On the bottom of the blank hole in the dental insert is fixed an elastic bushing in which is screwed the adjuster bolt. The dental implantate is useful in orthopedic stomatology and its advantages are expressed in its simplified design and simple operational technics.
