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 ajustified 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.

Malokluzije III klase karakterise razvijenija donja vilica u odnosu na gornju i skeletni i dentoalveolarni odnos III klase po Englu. U naucnoj literaturi postoji mali broj podataka o morfoloskim karakteristikama malokluzija u razlicitim populacijama, pa zato postoji opravdana potreba za ispitivanjem morfoloskih karakteristika kod malokluzije III klase u vojvodanskoj populaciji. Cilj rada bio je da se utvrde morfoloske karakteristrike malokluzija III klase; da se one uporede sa prosecnim vrednostima u populaciji koje su dobijene iz naucne literature i da se utvrdi korelacija izmedu ispitivanih parametara u gornjoj i donjoj vilici. Materijal i metode. Istrazivanje je sprovedeno kao retrospektivna studija na studijskim modelima ispitanika koji imaju dentoalveolarnu malokluziju III klase, a koji su leceni na Klinici za stomatologiju Vojvodine u Novom Sadu. Metodom slucajnog izbora odabrano je 50 studijskih modela. Podaci su statisticki obradeni sa nivoom znacajnosti p < 0,05. Rezultati. Dobijeni rezultati ukazuju na to da je suma sirine krunica donjih inciziva, duzina mandibularnog zubnog luka i mandibularne apikalne baze kod ispitanika sa malokluzijom III klase veca od prosecnih vrednosti u populaciji. Vrednosti zadnje sirine gornjeg zubnog luka u ispitivanoj grupi su manje u odnosu na prosecne vrednosti u populaciji. Zakljucak. Ispitanici sa malokluzijom III klase imaju vecu razvijenost donjeg, a manju razvijenost gornjeg zubnog luka.
