[Harmonic profile according to W. Arnett in patients with different types of occlusal relations].
Soft tissues facial profile was studied in 121 orthodontic patients by W. Arnett's method of side teleroentgenograms. The groups of patients with occlusal anomalies of I, II/1, II/2 and III classes were singled out. The profile appearance was determined by the form, position, size and correlation of maxillofacial structures, but soft tissues covering bone structures had also played their part in its forming. In patients with I class occlusal anomalies more harmonic profile was met oftener than in patients with II/1 class anomalies. Harmonic profile frequencies in patients with anomalies of the occlusal I and II/2 classes were statistically insignificant different from this parameter in patients with skeletal classes I and III. Results of the study showed that other factors (responsible for profile forming - incisors position and incline, soft tissues form and size) except occlusal relations were involved. Thus when X-ray cephalometric analysis is done it is necessary to use not only teeth-skeleton parameters but also soft tissues profile parameters. Only in this case it is possible to provide exact diagnoctic and to draw the adequate treatment plan.
