Study type | Interventional |
Patients at the Orthodontic Department of University of Aleppo Dental School will be selected if they meet the inclusion criteria then fixed orthodontic treatment with 0.018-inch slot MBT appliances will be applied for those patients. The aim of this study is to compare Two rebonding procedures by applying a split-mouth design. The clinical failure rates of the two rebonding procedures will be evaluated.
