Development of Intuitive Surgical Navigation System for Dental Implant Surgery by using Retinal Imaging Display

As dental implants have become an established treatment, their application to aggressive cases with insufficient quantity and quality of bone has increased. To perform safe and precise surgery, overcoming these difficulties, computer-assisted navigation systems have been developed. With conventional systems, surgeons feel anxious during operation because they have to manipulate instruments in the oral cavity while watching a surgical monitor. Thus, we have 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.
