An artificial joint comprising a first base element and a second base element that are pivotally connected to an intermediate body. A first protrusion extends from the first base element and is configured to be press-fitted into a screw device that is anchored to a first bone member, and a second protrusion extends from the second base element and is configured to be press-fitted into a screw device that is anchored to a second bone member. A related kit-of-parts is also described.

Artificial joint

An artificial joint for implantation in humans and animals, the joint comprising a joint body arranged between two base elements which are adapted to be connected to adjoining bone parts. The two base elements comprise horizontal and vertical retaining members respectively, that hold the joint body between them. The joint body comprises curved surfaces arranged to make sliding contact to corresponding curved surfaces of at least one base element. The joint body this way distributes the applied forces over a large surface to withstand the load initiated by the patient. The joint body is kept in position using pins held by retaining members at the base elements. The angle of motion can be predetermined by the design of the implant body to mimic the movement of a normal finger.

A saliva substitute, the characteristic feature of which is that it comprises water-soluble linseed polysaccharides. Said substitute is preferably in the form of an aqueous solution having a viscosity within the range of 1-30 mPa.s, most preferably 2-10 mPa.s. The substitute can be prepared by extracting the polysaccharides from linseed by means of water or a water solution containing inorganic salts. In addition to the fact that said substitute is useful as a saliva substitute it can also be utilized as a carrier for pharmaceuticals adapted for oral applications.

Saliva substitute

The invention relates to an implant material composition, its preparation, and its use for restoring bone tissue in a human or animal body. The composition comprises a particulate biocompatible bone tissue substitute material distributed in a bioacceptable mixture of (a) a water-based liquid, (b) a monoglyceride, and optionally (c) a triglyceride. The ingredients (a), (b) and (c) form an L2-phase or a lamellary liquid crystalline phase, and are present in such proportions within said phases that they are capable of being transformed into a cubic liquid crystalline phase or a reversed hexagonal liquid crystalline phase when contacted with an aqueous liquid. The phase conversion imparts to the composition such a high viscosity that it functions as an implant material as defined.

Implant material composition, preparation thereof as well as uses

An implantable device for supplying liquid to the oral cavity comprises a liquid container having means for keeping the liquid under pressure, a tube, one end of which being connected to the container, said tube consisting of a material which is suitable for subcutaneous location in the human body, and an lead-through bushing connected to the other end of said tube, said bushing consisting of or being coated with a biocompatible material for being implanted into a jaw bone, and comprising a nozzle opening provided with a filter.
