Class I (CI), Class II Division 1 (CII\/1) and Class II Division 2 (CII\/2) malocclusions were divided into three subgroups according to their vertical morphology as hypodivergent, normodivergent and hyperdivergent. The multivariate variance analysis (MANOVA) method was used in the comparison of measurement values according to vertical and sagittal morphology. The relationship between both A point-Nasion-B point (ANB) and Frankfurt-mandibular plane (FMA) angles and dental arch measurements was examined by Pearson correlation analysis. The significance level was received as\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.05.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>While vertical morphology has a statistically significant effect on mandibular arch length, sagittal morphology affects maxillary arch depth. The parameters influenced by both morphologies are maxillary and mandibular arch length, as well as maxillary intermolar width. The mandibular arch length was significantly shorter in hyperdivergent-CII-2 malocclusion (50.5 \u00b1 7.4 mm). Larger values were obtained in both mandibular arch length and maxillary arch depth measurements in CII-1 malocclusion compared to CII-2 malocclusion. The maxillary intermolar width was significantly shorter in hypodivergent-CII-1 malocclusion (46.8 \u00b1 3.4 mm), while it was higher in hypodivergent-CI malocclusion (51.1 \u00b1 3.4 mm). The maxillary arch length was the lowest in hyperdivergent-CI malocclusion (63.1 \u00b1 13.3 mm) and the highest in hypodivergent-CI malocclusion (72.8 \u00b1 7.6 mm).
