"Augmented Reality-Assisted Miniscrew Placement in Orthodontics: A Clinical Trial"

This is a pilot clinical trial designed to assess the feasibility and accuracy of augmented reality (AR)-guided mini-screw insertion in orthodontic patients. The study involves the use of CBCT imaging and digital intraoral scanning to create a 3D model of the patient's jaw. This model is then processed and integrated into an AR platform that allows real-time visualization of the ideal screw insertion site.

Participants are selected based on inclusion and exclusion criteria. After obtaining informed consent, CBCT and intraoral scans are performed. The proposed mini-screw location is determined digitally and projected using an AR device (tablet or headset) during the clinical procedure.

After insertion, a follow-up CBCT scan is taken to evaluate the deviation between the planned and actual screw positions (linear and angular deviation). Data on insertion time, patient comfort, and operator satisfaction will also be recorded.

The study is conducted at the Faculty of Dentistry, Al-Azhar University - Assiut Branch, with prior ethical approval obtained from the institutional review board.
