COMPARAÇÃO DA ALTERAÇÃO DO PERFIL TEGUMENTAR DE PACIENTES CLASSE III TRATADOS COM AS PRESCRIÇÕES ROTH E BIOFUNCIONAL

Abstract

Introduction: The objective of this study was to compare the cephalometric alterations in the integumentary profile of patients presenting with Class III malocclusions, treated by Biofuncional and Roth prescriptions. Material and Methods: The sample consisted of 63 patients with Class III malocclusion who were divided into two groups. Group 1 was composed of 30 patients (11 male and 19 female) with mean initial age of 20.39 who were treated with the Biofunctional technique for a mean time of 2.61. Group 2 consisted of 33 patients (22 male and 11 female) with mean initial age of 18.65 who were treated with the Roth technique for a mean time of 2.81. Teleradiographies were used in the initial and final lateral norm of the patients to compare the tegumentary alterations in the two groups. Intergroup comparisons were performed using chi-square and independent t-tests. RESULTS: Patients treated with the Biofunctional technique had a significantly higher upper lip than patients treated with the Roth technique at the end of treatment. Conclusion: There is no difference in tegmental profile alterations in patients with Class III malocclusion treated with Biofuncional and Roth techniques.
