3D Printed Reverse Twin Block for Class III Malocclusion
Sponsor: University of Baghdad
Summary
This RCT aims to evaluate the effectiveness of a novel 3D printed reverse twin block appliance in the management of maxillary deficiency in growing patients having class III malocclusion. The clinical outcomes of this appliance will be compared with the conventional reverse twin block appliance over 6 months treatment period. primary objective is evaluating of the effectiveness of 3DRTB in correcting sagittal discrepancies due to maxillary deficiency in class III malocclusion compared to conventional one while secondary objectives are assessment of transverse and vertical jaw relationship produced by 3DRTB compared to CRTB and to evaluate the soft tissue profile of class III patients and to evaluate the maxillary and mandibular incisor inclination, also assessment of patient perception with both appliances by using questionnaire and finally to assess the impact of 3DRTB on oral health compared to CRTB by using oral hygiene index.
