Abstract

Introduction. Class III malocclusions are characterized by a more prominent lower jaw compared to the upper jaw and a Class III skeletal and dentoalveolar relationship according to Angle. In the scientific literature, there is a small amount of data on the morphological characteristics of malocclusion in different populations, so there is a justified need to examine the morphological characteristics of Class III malocclusion in the population of Vojvodina. The aim of this study was to determine the morphological characteristics of Class III malocclusions, to compare them with the average values found in the scientific literature, and to determine the correlation between the examined parameters of the upper and lower jaw. Material and Methods. This retrospective study included subjects with Class III dentoalveolar malocclusion treated at the Dentistry Clinic of Vojvodina in Novi Sad. The method of random selection was used to select 50 study models. The data were statistically processed with a significance level of p < 0.05. Results. The obtained results indicate that the sum of crown width of the mandibular incisors, the length of the mandibular dental arch, and the mandibular apical base in subjects with Class III malocclusion are higher than the average values in the general population. The values of the posterior width of the maxillary dental arch in the examined group are lower compared to the average values in the general population. Conclusion. Subjects with Class III malocclusion present with a greater mandibular dental arch in regard to the maxillary dental arch.
