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

由于种植牙已成为一种成熟的治疗方法，它们在骨数量和质量不足的侵袭性病例中的应用越来越多。为了进行安全和精确的手术，克服这些困难，计算机辅助导航系统已经开发出来。使用传统的系统，外科医生在手术过程中会感到焦虑，因为他们必须在观察手术监视器的同时操纵口腔中的仪器。因此，我们通过结合视网膜成像显示（RID）和增强现实（AR）技术开发了一种新的手术导航系统，可以直接将术前模拟图像覆盖到外科医生的真实视图上。

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.
