1. An implant portion of an oral implant designed for supporting an artificial tooth structure comprising:

  • an implant body having threads over at least part of its exterior surface and being adapted to be threaded into an opening in a bone of a patient in the vicinity of the occlusal plane, which bone has been exposed by an incision in the covering fibromucosal tissue; and

    at least one channel formed such that it at least extends through the threads on the body for directing bone chips toward a base portion of the opening in the bone, one edge of the threads at one side of the channel being substantially at a right angle to the circumferential direction of the threads and the other edge of the threads at the other side of the channel being at an oblique angle to the circumferential direction of the threads, said one edge being adapted (i) to promote self-tapping of the threads in the bone, (ii) to shave off pieces of bone during threading of the implant portion into the bone, and (iii) to direct the pieces of bone into the channel such that the channel may direct pieces toward the base portion of the opening.
