ABSTRACT:
An implant for the jawbone includes a shaft portion and a conical retention portion which is provided with displacement projections. The displacement projections are sickle-shaped retention wedges which are provided on the retention portion located opposite each other. Since the retention portion is conical and the retention wedges result in an oval cross-section, the implant can be inserted into the prepared alveolus having the same shape and a rotation of at most 90.degree. results in locking of the implant in the interradicular alveolar bone to provide primary stability.
