中文摘要：

动态导航系统在口腔种植领域逐渐开始使用，系统能够术前规划种植体植入路径，术中实时可视化追踪种植钻针，避开重要解剖结构，提高手术安全性。本文将简述动态导航系统的发展，组成原理和临床应用，针对不同导航系统辅助常规种植体植入的精度进行探讨，并介绍动态导航系统辅助颧骨种植体植入术的精准度，分析导致临床误差的各种因素。

英文摘要：

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 assist the operators by avoiding critical anatomic structures to achieve safer surgery.Our article focuses on the development 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 dynamic surgical navigation systems for implants placement and to investigate the main reasons led the inaccurate outcome.
