When nonsurgical endodontic treatment fails, surgical treatment is an alternative approach for treating periapical disease. However, endodontic microsurgery (EMS), particularly in anatomically challenging areas, such as the posterior teeth, is a skill-sensitive task that can present a unique set of challenges for the surgeon. In recent years, digital guidance technology has been applied more frequently in dentistry. Dynamic navigation (DN) is a pioneering technology that uses an optical positioning device controlled by a sophisticated computerized interface and dedicated three-dimensional surgical path planning software program. This technique has also recently been introduced in the field of EMS to improve accuracy and avoid related complications. This case report presents a novel approach to DN-assisted EMS and describes its application in posterior teeth. After undergoing DN-assisted EMS, all patients were completely asymptomatic at the follow-up visit. Radiographic examinations performed immediately and 3-9 months after EMS revealed that the root resection was performed accurately without complications. The DN technique has been proven to be a feasible, predictable, and time-saving system for assisting EMS in cases requiring treatment in anatomically challenging areas, such as in the posterior teeth.
当非手术根管治疗失败时，手术治疗是治疗根尖周病的另一种方法。然而，根管显微外科手术（endodontic microsurgery，EMS），特别是在解剖学上具有挑战性的区域，如后牙，是一项对技能要求较高的任务，可能会给外科医生带来一系列独特的挑战。近年来，数字化引导技术在牙科领域的应用越来越频繁。动态导航（dynamic navigation，DN）是一项开创性技术，它使用由复杂的计算机接口控制的光学定位装置和专用的三维手术路径规划软件程序。这项技术最近也被引入 EMS 领域，以提高准确性并避免相关并发症。本病例报告介绍了一种新型的 DN 辅助 EMS 方法，并描述了其在后牙中的应用。接受 DN 辅助 EMS 治疗后，所有患者在随访时均完全无症状。EMS 后即刻和 3-9 个月进行的影像学检查显示，根切除准确无误，无并发症。DN 技术已被证明是一种可行、可预测且节省时间的系统，可用于辅助在解剖学上具有挑战性的区域（如后牙）需要治疗的 EMS。
