Orthodontic Treatment
All the enrolled patients will undergo conventional fixed appliance therapy by bonding straight wire Roth appliance in the maxillary arch. The bonding procedure will be standardized in all patients and performed by the same operator using light-cured composite. Levelling and alignment will then be started using the following wire sequence: 0.014-in nickel titanium (NiTi), 0.018-in NiTi, 17×25-in Niti, and 19×25-in Niti arch wires. The upper arch will then be stabilized using a 19×25-in stainless steel (SS) arch wire for 2 months. This stage will require approximately 6 months of treatment.
