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.

Outcome Measures

Primary Outcomes (2)

  • Linear Movement Discrepancies Between Digital Software Models and Clinical Models

    Translation movements (mm) were compared for each tooth between predicted models on Software predicted models and actual clinical models for the study groups

    an average of 1 year

  • Angular Movement Discrepancies Between Digital Software Models and Clinical Models

    Translation movements (Degrees) were compared for each tooth between predicted models on Software predicted models and actual clinical models for the study groups

    an average of 1 year

Study Arms (2)

part-time wear

ACTIVE COMPARATOR

Patients will be instructed to wear the aligner for 16 hours per day, then the aligner going to be changed to the next step according to its numerical order in the software

Device: clear aligner treatment for orthodontics patients

Full-time wear

ACTIVE COMPARATOR

Patients will be instructed to wear the aligner for 22 hours per day, then the aligner going to be changed to the next step according to its numerical order in the software

Device: clear aligner treatment for orthodontics patients
