The patients were categorised into three groups. Groups 1 and 2 exhibited menton and ramus deviation to the same side. Menton deviation was larger than ramus deviation in Group 1, whereas Group 2 showed the inverse relation. Group 3 patients showed menton and ramus deviation in opposite directions. Occlusal contact area (OCA), relative bite force (RBF), and temporalis anterior (TA) and masseter muscle (MM) activity at maximum clenching were measured using T\u2010Scan Novus system and Bio\u2010EMG\u2010III. Statistical analysis was performed using the <jats:italic>t<\/jats:italic>\u2010test, one\u2010way analysis of variance with Bonferroni correction and Spearman correlation (<jats:italic>\u03b1<\/jats:italic>\u00a0=\u00a0.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Compared with normal participants, the patients had smaller OCA and greater asymmetry in the distribution of masticatory muscle activity. Greater ramus deviation was associated with smaller OCA in Group 1 but with larger OCA in Group 3.

In Group 2, greater ramus deviation was related to stronger MM activity on the deviation side.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Deviation of the menton and
