Abstract: Joint prosthesis comprising a joint section (10) having a web (16) of an elastomer, arranged between two pins (11) which are inserted each in one of two tubular screws (17) to be secured in the bones between which the joint prosthesis shall be arranged, the pins being secured in the web by means of flanges embedded into the elastomer. Pins and screws comprise a biocompatible material.

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: This invention relates to a joint prosthesis for permanent anchorage in the bone tissue of a joint in a human body, for instance a knee joint. The joint prosthesis comprises an anchorage device (3, 4; 7-10, 11) disposed to be implanted into the bone tissue at a first operation so that it remains in unloaded condition during a healing phase during which the function of the joint is not prevented and an articulation device (5, 6; 13, 12) which is arranged to be connected to the anchorage device only at a second operation after the said healing phase.

Abstract: The present invention relates to a device for providing a permanent pathway between the abdominal cavity and/or organ located in the abdominal cavity and the exterior of the body. The device is made of commercially pure titanium or at least coated with titanium on the surfaces which directly contact the abdominal wall tissue. The device comprises a first anchorage portion, designed for implantation into the connective tissue of the abdomen during the first operation, a covering screw with plug for blocking of the central opening in the anchorage portion during the healing phase and a skin penetration portion in the form of a titanium tube for connection to the anchorage portion during the second operation after prior removal of the covering screw with plug.

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 invention relates to a method of packaging artificial implants in a sterile and contamination-free manner, comprising applying the implant inside a closable capsule made of the same material as the implant, thereafter enclosing the capsule in a hermetically sealable outer casing and sterilizing the package thus produced, and also to a package for performing the method.

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.

Abstract: A bone prosthesis and the method of securing it in place, in which the prosthesis is formed as a tubular support member having perforations therein, the end of the bone is bored, the tubular support member is introduced into the bore and cement is then introduced into the interior of the tubular support and passes out through the perforations to provide the midterm anchor on the walls of the bone. The cement will damage the tissue where it contacts the tissue, but the remainder of the tissue of the bore is undamaged and this grows inwardly to form a long term anchor between the tubular support and the bone. A prosthesis body is located and secured in place e.g. mechanically or by cement, in the tubular support member.
