The application and development of dynamic navigation system in implant dentistry

Dynamic surgical navigation system has been wildly used in implantology, the navigation surgical system provide preoperative trajectory planning. Moreover, the constant visualization of drilling trajectory during operation as⁃ sist the operators by avoiding critical anatomic structures to achieve safer surgery. Our article focuses on the develop⁃ment and function of dynamic navigation system to evaluate the accuracy of dynamic surgical navigation system when used for regular implants and zygomatic implants placement. We aim to discuss the accuracy of different brand of dynam⁃ ic surgical navigation systems for implants placement and to investigate the main reasons led the inaccurate outcome.
