Introduction. The characteristically enlarged mandible associated with acromegaly may have an influence on the function of the stomatognathic system. Aim. The aim of the study was to evaluate occlusion using a T-scan III occlusal analysis system in patients with acormegaly. Material and Methods. The study group was 22 people diagnosed with active acromegaly; and the control group comprised 22 healthy individuals with full dentition. The analysis was conducted using parameters measured with the T‑scan III Tekscan occlusal analysis system. Results. The average values for the differences between the right and left side of the dental arch were statistically different in the group with acromegaly. A significant redistribution of occlusal forces to the anterior part of the dental arch was also observed. The occlusal time (OT) was longer than standard and the occlusal centre of force was located outside the reference area. Conclusions. The occlusal analysis system showed changes in the contacts between opposing teeth as well as in the distribution and balance of occlusal forces in comparison with the control group.

Key words: acromegaly, T-scan, occlusal analysis system.
