A feasibility study of a new method to enhance the augmented reality navigation effect in mandibular angle split osteotomy

This study is designed to compare the different situation between the traditional image guide pattern and deviation reminds added pattern in the model trials. The AR system can track the model and surgical tools at the same time. Five craniofacial surgeons and engineers participated in this study. The navigation points were ensured with the traditional image guide pattern and deviation reminds added pattern for each one. Then, the position error, orientation error and time requirement were recorded for statistical analyses in the study. There was a statistically significant difference between the deviation reminds added pattern and traditional image guide pattern for both engineers and surgeons in orientation error and navigation time (p<0.05). Additionally, there were no significant differences between engineers and surgeons in errors (p=0.117) and time requirements by the team (p=0.913). Our results suggest that the deviation reminds added pattern is better than traditional image-guided pattern for both engineers and surgeons. In addition, the extra information can improve the performance of surgeons in navigating position assurance.
