摘　　要：根管内器械分离是根管治疗过程中最棘手的并发症之一。由于折断的器械将会阻碍根管系统的清理和成形,使后续治疗难以顺利进行,所以对根管治疗的效果及预后均具有潜在的影响。导致根管内器械折断的原因非常复杂,且受多种因素的共同影响,从而使每个器械分离的病例都有其各自的特点。因此,关于成功取出根管内折断器械的治疗方法尚无统一的标准和操作过程。本文就近年来报道的有关根管内折断器械的取出技术和方法作一综述,以期为临床工作提供帮助。One of the most troublesome problems in endodontic treatment is separation and lock of the in- struments in root canals. Irretrievable intracanal separation of endodontic instruments may block the pathway to the api- cal constriction and thus hinder the effectiveness of shaping and cleaning procedures, which may affect the prognosis. The causes of the separation of endodontic instruments are multifactorial and complicated. Due to its own unique char- acteristics of every case of fractured instrument in root canal, there is still no standardized management and procedure for successful fragment removal. This article summarizes the current techniques and approaches of removing separated instruments.
