[The demonstration of cellular reactions in the temporomandibular condylar cartilage by NMR microscopy. The basic research for high-resolution NMR tomography of the temporomandibular joint].
The regional resolution of modern imaging methods is not good enough to clinically objectify changes to the cartilage of the temporomandibular joint, for example in functional orthodontic treatment. NMR microscopic studies of an intact temporomandibular joint preparation were done experimentally in the domestic pig on the basis of 1H-NMR relaxometric measurements in specimens of condylar cartilage. We succeeded in representing the cartilage of the temporomandibular joint down to the cellular level, and in demonstrating regeneration processes as a late sequela of surgery on the temporomandibular joint. The results are discussed with respect to their importance for future high-resolution magnetic resonance imaging of the temporomandibular joint.
