Prototype of Augmented Reality Technology for Orthodontic Bracket Positioning: An In Vivo Study

To improve the accuracy of bracket placement in vivo, a protocol and device were introduced, which consisted operative procedures for accurate control, computer-aided design, an augmented reality–assisted navigation system. The present study evaluated this protocol. Methods: Thirty-one incisor teeth tested from four participators. bonded by novice expert orthodontists. Compared with control group Boone gauge experiment reality-assisted system, our used brackets measurement. evaluate accuracy, deviations positions measured. Results: system same 31 cases. priority bonding between or was decided tossing coins, then debonded other technique used. medium vertical (incisogingival) position deviation AR groups orthodontist 0.90 ± 0.06 mm 0.51 0.24 mm, respectively (p < 0.05), 0.40 0.29 0.08 0.05). No significant changes horizontal noted regardless experience use Conclusion: increased rate incisogingival direction helped guide within acceptable clinical error approximately 0.5 mm.
