title: [The surface topography and ultrastructure of the human TMJ, a SEM and TEM study].
abstract: Two specimens of human temporomandibular joints were studied with scanning electron microscope and transmitting electron microscope. The whole articular surface of TMJ has an undulated or ovoid appearance. Each part of the joint has its own surfaces property. A gel-like material was found on the articular surfaces of condyle, glenoid fossa and disk. The arrangement and size of collagen fibers are also different in different parts of the joint. In many places of a specimen from a cadaver who had serious grounding on his teeth, the gel-like material has disappeared and some fibrous material has formed on the articular surface.
