Changes in soft tissue profile during the treatment of Class III malocclusion treated with Class III activator

Abstract

Objective: This longitudinal retrospective cephalometric study was undertaken in an attempt to evaluate the effect of Class III activator on the soft tissue structures in subjects with skeletal Class III.

Methods: The material consisted of cephalometric films of 26 Class III patients (13females and 13 males, with a mean age of 13.58±4.38 years). Each treated patient was matched before treatment with Class III subject for sex and age. Differences at T1 and T2 were examined using paired t-test.

Results: After treatment the patients' soft tissue profile improved significantly compare with before treatment.

Conclusion: Soft tissue changes were found in patients treated by Class III activator in skeletal Class III patients.

Clinical relevance: Class III activator may be an efficient method to improving soft tissue facial profile in Skeletal Class III malocclusion.
