Thickness measurements and micro-CT imaging of human temporo-mandibular discs.

ABSTRACT: The temporo-mandibular joint (TMJ) links the mandibular condyle to the skull, with an interposed fibrocartilaginous articular disc. The TMJ disc has a nonuniform thickness that matches the topographic relation between the temporal bone and the mandibular condyle. The disc is a stress-distributing and load-absorbing structure that is capable of deforming and adapting its shape to that of the articular bone surfaces. The aim of this study was to analyze the morphology of human discs through thickness measurements. Forty-four temporomandibular joint discs were dissected bilaterally from 22 formalin-fixed human postmortem subjects. The thickness of each disc was manually measured at nine points distributed in a grid formed by three zones in the anteroposterior direction (anterior band, interme
