Research Abstract

We created a new dental fiberscope. However, due to the influence that focus depth and angle changes have on the scope, comprehending the device position and the precise target setting were difficult to ascertain consistently. Therefore, we developed a dental fiberscope that can be navigated. We verified the total accuracy of the dental fiberscope and resultant position accuracy of the navigation system. At the result, The navigation system error was 0.480mm±0.086mm(Difference X asis : 0.051mm±0.229mm, Y axis : 0.088mm±0.202mm, Z axis 0.254mm±0.260mm)
