Dentofacial Morphology of Class II Division 1

Ilga Urtane, Gundega Jakobsone, Jolanta Pugaca

Summary

In this study dentofacial morphology was compared in the age groups: up to 12 years; 12-16 years and older than 16 years. The sample comprised 212 randomly selected lateral cephalograms of orthodontically untreated patients (80 males and 132 females). Patients were divided into 3 groups based on the mandibular plane angle. Differences in the sagittal, vertical and cranial measurements between the groups were analyzed with ANOVA test. Linear regression analysis was used to calculate association between the dentofacial morphology and age. Mean values of both maxilla and mandible showed retrognathic position. The male subjects comparing with females had greater anterior and posterior cranial base measurements and larger lower jaw body in all of the age groups. Anterior and posterior cranial base increased with age, except in the patients with high mandibular plane angle. Mandibular plane angle and articular angle increased significantly (p< 0,05) only in males us they became older, that could be reason to assume growth modification to be more effective for them.

Key words: dentofacial morphology, cephalograms, growth pattern.
