To examine all lateral excursions, patients are instructed to close lightly into centric occlusion and subsequently slowly execute maximum active right, left, and protrusive mandibular movements while maintaining contact between the mandibular and maxillary teeth (Figure 3.16).

(M. Ziad Al‐Ani, Robin J.M. Gray.)

The anterior guidance in the mandible can be on the canine teeth, which is ideal because this means that the patient can move the mandible from side to side with immediate disclusion of the posterior teeth (Figure 3.17).

(M. Ziad Al‐Ani, Robin J.M. Gray.)

There can be group function where the canine, premolar, and molar teeth all contact during lateral excursion of the mandible. This is equally acceptable, preferably with the anterior contact being firmer than the posterior contact.
