An interventional study of Augmented Reality and Conventional screw placement in Orthodontic, sponsored by Al-Azhar University. Not yet recruiting at 1 site in Egypt. Per ClinicalTrials.gov, last updated 2025-08-08.
Sponsored by Al-Azhar University · Not applicable, Interventional, and Treatment
This study aims to evaluate the effectiveness and accuracy of using Augmented Reality (AR) technology in the placement of mini-screws (Temporary Anchorage Devices) during orthodontic treatment. By combining CBCT images with digital dental scans and visualizing them using AR, clinicians can place mini-screws more precisely. The study is a pilot clinical trial involving patients at the Faculty of Dentistry, Al-Azhar University - Assiut Branch.
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.

2. History of craniofacial trauma, surgery, or congenital anomalies in the maxillofacial region.
3. Ongoing periodontal disease or poor oral hygiene.
4. Pregnancy or lactation.

Participants in this group will undergo mini-screw placement using augmented reality (AR) guidance to enhance accuracy and reduce placement errors
Device: Augmented Reality
Participants in this group will undergo mini-screw placement using conventional placement
Procedure: Conventional screw placement
Participants in this group will undergo mini-screw placement assisted by augmented reality (AR) technology. A customized AR system will guide the clinician in real-time to ensure optimal screw positioning, improve accuracy, and minimize placement errors.
Participants in this group will receive mini-screw placement using the conventional freehand method without augmented reality assistance. The screws will be placed according to standard clinical protocols based on anatomical landmarks and clinician experience
Accuracy of screw placement
Accuracy will be assessed using CBCT imaging compared to planned position
Time frame: 1 week post-op
Plan to share: No — NO plan to share
