THE TREATMENT EFFECTS OF THE COMBINED APPROACH: BRACESWITH PREFABRICATED MYOFUNCTIONALAPPLIANCE FOR GROWING CLASS II PATIENT

Objective:To evaluate the effect of combined treatment approach: braces with myofunctional appliance (trainer-T4B) on dentoalveolar, sagittal and vertical skeletal level in growing individuals with Skeletal and Dental Class II.

Methods:Twenty teenagers with permanent dentition were treated with fixed appliance-braces in combination with myofunctional appliance (trainer-T4B). All patient completed thetreatment with occlusal Class I molar relationship. The patients made initial and final profile X-rays with cephalometric analysis. The evaluation of the treatment effects was made by comparing the initial and the final cephalometric analysis.

Results:Significant sagittal skeletal changes were observed on all sagittal skeletal parameters, except for SNA°. A high positive association was found between the ANB angle change and Wits change. The changes in the rest of the vertical skeletal measurements were significant for two, including SN-M° and Go°. The dentoalveolar measurements showedsignificant changes in all parameters, except for i/M° where the change was marginally significant.

Conclusion:The chosen treatment approachwaseffective for growing skeletal and dental Class II patients with permanent dentition.
