This study was designed to explore whether overjet and overbite relationships might be correlated with the anteroposterior and vertical craniofacial dimensions. The material used to test this hypothesis was lateral cephalometric radiographs from 92 adults (49 women and 43 men) with Angle Class I molar and canine relationships and a harmonious profile. Data were analyzed using the t‐test, Kendall's tau‐b correlation and cluster analysis. The results revealed that a) women exhibit an increased overjet compared to men, and smaller vertical facial dimensions; b) there is a significant correlation between overjet and overbite, overbite and posterior facial height, and overbite and mandibular angle; c) in the two groups of individuals that were separated on the basis of overjet and overbite, only the mandibular plane exhibited a statistical difference between the two groups: groups with small values for overjet and overbite possess high mandibular angles and a decreased mandibular plane angle accompanies large values for overjet and overbite; d) groups separated on the basis of mandibular plane angle were not independent from the groups separated on the basis of overjet and overbite. In summary, occlusal characteristics are not found to be associated with any particular skeletal pattern.
