Examination findings revealed mandibular range of motion with maximum opening of 54 mm, protrusive excursion
of 05 mm, left lateral excursion of 14 mm and right lateral excursion of 12 mm.
The teeth setup of complete den- tures with lingualized occlusion was arranged as fol- lows: the functional maxillary palatal cusps of the posterior teeth were set in the central groove of the mandibular posterior teeth in lateral and protrusive excursions
. The maxillary buccal cusps were elevated and had no contact with the mandibular buccal cusps in both centric and eccentric movements.
During lateral or protrusive excursions
, the six anterior maxillary teeth, together with the six anterior mandibular teeth guide the mandible so that no posterior occlusal contacts occur.
