1 Soft tissue profile changes in patients with Angle Class II division 1 malocclusion treated using a function regulator

Abstract

The functional appliance is widely used in orthodontic practice for treating patients with skeletal problems. We treated 29 patients (18 males and 11 females, average age 11.6 years) who had Angle Class II division 1 malocclusion using the function regulator II. Cephalograms taken before and after treatment were traced and analyzed. Five esthetic indices were used to evaluate soft tissue profile changes in the patients. Most of the indices tended to normal values and the soft tissue profile of the patients were improved after the functional treatment. However, individual changes differed and second stage treatment was still required for some patients. Early function regulator treatment reduces the need for second phase treatment, reduces the difficulty of late treatment, and shortens the period of late treatment. It is considered on efficient method of treatment.
