Abstract
An implant for fixing an artificial replacement tooth to a jaw bone comprises a post for firmly holding the replacement tooth and at least two hollow cylindrical bodies. The bodies have mutually parallel axes, are rigidly connected to the post and open at one axial end. The cylindrical wall of each body is intended to be inserted into the jaw bone and is provided with means defining passages through which the jaw bone can grow to secure the implant to the jaw. A group of teeth may be fixed to the jaw by the use of a bridge and two or more implants.
