CLASS II/1 REHABILITATION WITH FUNCTIONAL APPLIANCES IN GROWING PATIENTS-INFLUENCE ON FACIAL PROPORTIONS

Abstract

Aim of the study. Orthodontic treatment intends to create a harmony between dental, muscular and osseous components. The purpose of this study was to evaluate, using proportional indexes, the effect of functional therapy on facial aesthetics rehabilitation, in class II/1 patients. Material and methods. We selected 60 patients with class II/1 malocclusion, aged between 6 and 12 years, treated with functional appliances. Specific indexes on standard photography at the beginning and the end of the treatment were assessed: F2- Lower face-face height, F3-Mandibulo-face height, F4-Mandibulo-upper face height, F5-Mandibulo-lower face height. Results. Statistically significant differences were noticed for F4 and F5 (p<0.005) for both age groups (6-9 years, 9-12 years) and both genders. Conclusions. Functional treatment demand intrinsic motivation and for this reason, two stage rehabilitation in class II/1 malocclusion can be commenced in the second phase of the mixed dentition
