Introduction. Different malocclusions indicate different thickness of facial
soft tissue. Objective. The aim of the study was to establish the differences
in the thickness of facial soft tissue profile in persons with dentoskeletal
Class II/1 and II/2 relationship. Methods. In the study we used cephalometric
rendgenograms profile analysis of 60 patients aged 12-18 years of the Dental
Clinic in Niš who had not previously undergone orthodontical treatment.
According to the dentoskeletal jaws relations the patients were divided into
two groups with Class II division 1 and Class II class division 2. In all of
them the standard dentoskeletal profile analysis by Steiner and soft tissue
profile analysis by Burston was done. The obtained findings were
statistically analyzed and the comparison between the studied groups was
performed. Results. The results indicated the following: in the patients with
Class II/1 relationship there was a significantly thinner upper lip (t=5.741;
p<0.0001), thinner upper lip sulcus (t=3.858; p<0.001) and significantly
thinner lower lip (t=2.009; p<0.05) in relation to the patients with Class
II/2. Compensatory effect in the Class II/1 patients was more distinctive in
females, as their soft tissue profiles were thicker. In Class II/2 patients
this relationship was in favor of males. Conclusion. The facial soft tissue
profile indicated significant differences in the thickness dependant on the
type of malocclusion and gender. Because of their great variability and a
significant participation in the formation of the profile, while planning
orthodontic therapy, it is necessary to pay them full attention, with
obligatory analysis of the dentoskeletal profile.
