Abstract

A practical method of research on cadaver specimen heads was designed from a systematic review of the existing literature in order to differentiate from conjecture the experimental proof of the axes of rotation of the condyles during mandibular border movements.

An anatomo-physiological study on eight human cadaver heads, using the gnathologic technique of Dr. R. Lee for recording mandibular movements, was done to study the intimate mechanism of the temporomandibular joints, with the hope of contributing support to this new method of recording.

It was established that rotational mandibular border movements are induced by hard structure topography of the temporomandibular joints. Rotational movements of opening and closure in centric relations are governed by the horizontal hinge axis; it passes through the condyle at the level of the medial pole and is concentric to the medial articulating incline of the condyle.

Lateral rotational movements, in the absence of sideshift, are induced by the topography of the external articulating incline of the condyles, and governed by an oblique axis which passes through that incline. The oblique axis is also perpendicular to the slope of the eminence in centric.
