研究概览
简要总结
This is a randomized controlled trial evaluating the severity of root resorption in maxillary teeth following En masse retraction using Mini screws, Friction mechanics and Frictionless mechanics.3 group of patients will be included in the study .Prior to retraction CBCT will be taken .Patients in group 1 will undergo retraction using stainless steel mini implants placed between second premolar and first molar as anchorage .Patients in group 2 will undergo retraction using soldered brass hooks with active tie backs . Patients in group 3 will undergo retraction using tear drop loops .Post op CBCT will be taken after retraction in all the 3 groups. Primary outcome is to evaluate the severity of root resorption in maxillary teeth following en masse retraction . Secondary outcomes include Root length ,Axial dimension of the root and Vertical alveolar bone level .
