Malocclusion, Angle Class I
Conditions
Brief summary
14 Patients with mild to moderate crowding and spacing will be selected according to inclusion criteria. Treatment planning will be done on Maestro® software. An impression will be taken and scanned by an extra-oral scanner. The models will be 3D printed and aligner trays will be fabricated to be delivered on biweekly basis to be worn 16 hours per day for one group and 22 hours for the other group. Superimposition of the achieved clinical model over the predicted model will be done. Linear and angular measurements will be calculated for each tooth.
Detailed description
Clear removable retainers could be related to clear aligners. Wearing time of retainers has been suggested that it could be changed from full time to part-time during the night only. A similar approach could be done to determine the effect of wearing time of clear aligners on treatment outcome. The standard duration per day for wearing the appliance is 22 hours. However, is part-time wearing (16 hours) would have the same effect? Therefore, a randomized clinical trial is needed to compare the effect of partial wearing of the aligner versus full time. Moreover, studying the predictability and accuracy of treatment using Maestro software.
