Articular coverings :

The smooth slippery, pressure bearing tissue carpeting, the surfaces of the bones varies in thickness across different articular areas. It is essentially a bed of tough collagen fibres bound by special glycoproteins. On the condyle, the tissue is thickest in anteroposterior direction and thickness is greater medially (average measurements 0.37 mm laterally and 0.48 mm medially). On temporal component, it is thickest along articular eminence and preglenoid plane. The thickness is less medially (0.49 mm and 0.36 mm for eminence and plane respectively laterally and 0.45 mm and 0.34 mm medially). In the depth of the mandibular fossa the thickness of periosteum is merely 0.07 mm. Continue reading →
