Abstract: An elongate cylindrical body member is adapted for permanent anchoring of its lower end into bone tissue and constructed to support an attached device such as a tooth at its upper end. The body member has an external screw thread formed in its outer surface, and at least one cavity defined therein adjacent its bottom end. Each cavity forms at its intersection with the screw thread at least one cutting edge for self-tapping as the body member is screwed into the bone tissue. Such cavity defines a total volume within the outer surface of said body member sufficient to retain all the bone tissue material which is removed as a result of the self-tapping operation.

Abstract: The reaction product of H.sub.2 O.sub.2 and metallic titanium, a titanium peroxy radical gel, exhibits oxidizing and anti-inflammatory effects and is used, for instance, as a biocompatible oxidant, an anti-inflammatory agent or in vitro coating of an implant body. The gel-like product is produced by treating metallic titanium with H.sub.2 O.sub.2.

Abstract: A fixture intended for implanting and anchoring in bone tissue, particularly in bone tissue of the jaw, to support a prosthesis such as the crown of a tooth. The fixture has at least a surface layer of material compatible with the tissue, such as titanium. The fixture comprises a lower shaft portion with external threading and an upper, smooth, neck portion. The lower portion is arranged to be screwed into a hole drilled in the bone tissue. The diameter of the hole is substantially in agreement with the core diameter of the shaft portion. The diameter of the neck portion lies within the interval between the outer diameter of the thread on the shaft portion and the core diameter of the shaft portion. The neck portion has an axial length exceeding the settlement in bone level which normally occurs upon use of the fixture.

Abstract: The present invention relates to a device for securing a plurality of teeth to at least two attachment elements (2) implanted in the alveolar bone (1), said device comprising an essentially rigid splint (3), preferably of titanium or titanium alloy, and assembly means (5) for removably fastening a row of teeth (6) to said splint (3), the splint being arranged at least between said attachment elements (2) to absorb and distribute the load arising upon use.

Abstract: The present invention concerns a positive model 1 of a jaw with implanted fixture means and which is intended for the manufacture of artificial teeth attached to the fixture means via distance means 22. In the model 1 every distance organ 22 is corresponded by a dummy 2, the upper part of which having the same form as the distance organ 22, protruding over the alveolar arch, and the lower part of which including locking means for the retention of the dummy 2 in the casting material of the model 1. The invention also includes a method and means for the manufacturing of the model 1.
