  • Patent number: 4778472
    Abstract: 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.
