Is the mandibular posterior position an important factor that leads to obstructive sleep apnea (OSA)? In order to determinate that, we conducted the following study on 2 groups of patients, each with 22 subjects. The first lot (control lot) contained 9 males and 13 females, aged between 21 and 32 years, with a diagnosis of Angle Class II malocclusion; the second lot (study lot) made up of 16 males and 6 females, aged between 35 and 60 years, with mild OSA established by polysomnography. The diagnosis of Angle Class II malocclusion was based on assessing SNA, SNB and ANB angles on lateral cephalograms. By correlating these angle values we can conclude that our investigated patients with mild OSA had an Angle Class II skeletal pattern, but less severe than in the control group.
