A concerted effort of the lateral pterygoid muscles helps in lowering the mandible and opening the jaw, whereas unilateral action of a lateral pterygoid produces contralateral excursion (a form of mastication), usually performed in concert with the medial pterygoids.

The lateral excursion of the mandible is measured in de-grees and is called the Bennett angle.

The laterotrusion of the mandible is often combined with the clicking of the temporomandibular joint. An optoelectronic measuring method renders it possible to exactly record the clicking and the position of the mandible at this moment. With this method 25 patients with an initial clicking were observed.

In a young subject group, the movements of left and right mandibular laterotrusion were measured at the incisal and the lateral pole point of the working side condyle. All samples were divided into one of two groups according to the mesial (M) or distal (D) canine guidance.
