The sagittal skeletal pattern was classified in Class I, II, and III according to ANPg angle and the vertical growth pattern was classified as hypodivergent, normodivergent, and hyperdivergent  \naccording to SNGoGn angle. Maximum mouth opening (MM0) records and 20% and 80% of these values in the normal distribution curve were considered for analysis purposes.  \nResults: The median age was 23 years (IQR, 20-28), and the mean  \nMMO was 52.1 mm (SD: 6). There was a statistical difference regard  \ning the mouth opening according to sex (P:0.01) and vertical growth  \npattern (P: 0.02). The post hoc test (Tukey) showed men (53.6 mm)(SD 6.43) open the mouth more than women (51.4 mm) (SD 5.72), and hyperdivergent patients (50.6 mm) open less than hypodivergent (52.8 mm) and normodivergent (52.5 mm). The 2-way ANOVA tests regarding the low and high mouth opening patterns confirmed the previous findings ofthe general sample.  \nConclusions: sex and vertical growth pattern seem to influence the amount of mouth opening.  \nKeywords: Orthodontics.
