Intuitive Surgical Navigation System for Dental Implantology by Using Retinal Imaging Display

What is it about?

We have been developed a novel surgical navigation system by combining the retinal imaging display (RID) and the augmented reality (AR) techniques that can directly overlay pre-operative simulation images onto the real view of the surgeon.

Why is it important?

We proposed the dental implant surgical navigation system by combining the AR technology and the RID and its image overlay procedure, and our procedure proved to be performed as a real-time image overlay. By implementation of the LMedS method, more robust calibration was achieved. Further development of the markers will be planned to decrease the reprojection errors by using the other markers including known sampling points fixed on the patient’s oral cavity. To achieve clinical applications of this system, evaluation of a fiducial registration error (FRE) and a target registration error (TRE) and the procedure by real CT data is in progress.
