Markerless augmented reality-guided mini-screw placement: A clinical case series

Area of Science:

• Dentistry
• Orthodontics
• Medical Technology

Background:

• Precise placement of orthodontic mini-screws is crucial to avoid damaging dental roots, nerves, blood vessels, or the maxillary sinus.
• Traditional methods lack precise visualization of local anatomy, increasing risks.
• Digital advancements like 3D virtual planning and CT-based surgical guides improve treatment simulation and surgical mapping.

Purpose of the Study:

• To evaluate the efficacy of augmented reality (AR)-guided systems for precise orthodontic mini-screw insertion.
• To assess the potential of AR technology in preventing complications associated with mini-screw placement.

Main Methods:

• Three patients requiring precise orthodontic mini-screw insertion were included in this study.
• Augmented reality (AR)-guided systems were utilized to assist in the accurate positioning of orthodontic mini-screws.
• Postoperative radiographs were used to confirm successful placement and assess for any root damage.

Main Results:

• Successful placement of orthodontic mini-screws was achieved in all cases without any damage to the tooth root.
• The non-invasive AR-guided system effectively highlighted the precise position of the tooth root, aiding in accurate placement.
• AR-assisted positioning showed potential in reducing mini-screw failure rates.

Conclusions:

• Augmented reality (AR)-guided systems offer a promising tool for precise orthodontic mini-screw placement.
• This technology enhances safety by potentially avoiding root damage and reducing failure rates compared to traditional methods.
• AR systems provide benefits such as adaptability, real-time adjustments, and cost efficiency for clinicians.
