Endodontic treatment of calcified canals presents a major challenge because of the high incidence of complications, such as perforation, canal geometry alteration, and loss of dental hard tissue. The dynamic navigation technique uses an optical tracking system for real-time navigation to guide the operator to drill according to the preoperative plan and obtain access to the calcified canals. This article describes in detail the use, advantages, disadvantages, and limitations of a novel dynamic navigation system in 2 cases with severely calcified canals. The findings in these cases demonstrate that dynamic navigation system is a promising technique for locating calcified root canals.
根管钙化是治疗的难点，易导致并发症，如穿孔、根管形态改变和牙体硬组织丧失等。动态导航技术使用光学跟踪系统进行实时导航，指导术者按照术前计划进行操作，从而进入钙化根管。本文详细介绍了在 2 例严重钙化根管中使用新型动态导航系统的方法、优点、缺点和局限性。这些病例的结果表明，动态导航系统是寻找钙化根管的一种很有前途的技术。
