    摘要： The dental prosthesis is adapted for insertion into a socket formed within the patient's jaw. It comprises an elongated shaft defining a proximal region, a distal region, and a tip. A soft porous pad extends distally from the shaft tip. The distal region is preferably biocompatible, porous, soft, resilient, deformable, tissue-ingrowth promoting, and has a compressive stress per unit of strain which is substantially smaller than that of adjacent bone.

    摘要： The prosthetic mini-condyle is for use with a prosthetic glenoid fossa. The mini-condyle covers an excised natural condyle having a superior cut surface and a lateral cut surface. The mini-condyle has a superior, convexo-planar articular face and an inferior flat face. A shank extends inferiorly from the inferior face and is adapted to become secured to the lateral cut surface. The flat interior face is adapted to abut against the superior cut surface. Preferably, a porous bicompatible coating is bonded to the inferior face of the condyle and to the medial face of the shank.

    摘要： The surgical TM joint implant has two-parts: a first part which covers or replaces the natural glenoid fossa and articular eminence of a natural TM joint, and a second part which replaces the natural condylar head of the joint. The first part includes a plate having a fossa cavity defined by a relatively deep concave portion and an anteriorly located concavo-planar portion. The second part has a condylar head defining a convexo-planar, articular face for engaging the concavo-planar surface and establishing therewith a planar contact area which minimizes the unit stress transmitted between the first and second parts, thereby providing for an even load distribution between their engaged planar surfaces.

    摘要： The present invention relates to a fixed volume prosthetic urinary bladder for use in a human being. The invention, more particularly, concerns a prosthetic urinary bladder comprising a vent channel having a removable cap and a urethral discharge valve. The present invention is intended for implantation in a human being such that the vent channel protrudes through the abdominal wall and the vent cap lies flush with the outer surface of the abdomen.

    摘要： A composition of material suitable for in vivo implantation to provide an environment in which normal tissue growth is fostered which composition is a porous fibrous structure in which the critical surface tension of the fibers is 35 dynes per centimeter or higher. This composition in the preferred form is a porous structure of carbon or graphite fibers bonded together by sintered polytetrafluoroethylene in a manner to expose a maximum amount of fiber surface.Another composition of material suitable for implantation for wear surfaces includes carbon fibers and polytetrafluoroethylene resin and is processed to align the carbon fibers with the wear surfaces. The method of preparing both material includes the step of mixing, filtering, compressing, rolling, sintering and drying. The method of stabilizing appliances or implants includes bonding the ingrowth material to the appliance or implant. Also the combination of the ingrowth material with appliances, tendon replacement elements and wear material are included.
