The present study reports a case of intentional replantation (IR) for a right mandibular second premolar (#45). For the present case, root canal retreatment was first considered after removal of the metal post and core. When the metal post and core could not be removed from #45, micro-apical surgery or intentional tooth replantation was performed. Six-month postoperative evaluation revealed that the right mandibular second premolar had no obvious symptoms of discomfort, and the clinical follow-up revealed uneventful healing and good bone regeneration. The short-term clinical efficacy was acceptable. For cases with root canal treatment failure, when the apical surgical access could not be established due to the adjacent important anatomical structures, IR may be employed as an accepted endodontic treatment procedure. Key Words: Root canal treatment failure, Post-core crown, Root canal retreatment, Intentional replantation.
本研究报告了一例右侧下颌第二前磨牙（#45）的 意 外 再 植（IR）病例。对于本病例，在去除金属桩核后，首先考虑进行根管再治疗。当无法从#45 去除金属桩核时，进行根尖显微手术或 意 外 再 植。术后 6 个月评估显示，右侧下颌第二前磨牙无明显不适症状，临床随访显示愈合顺利，骨再生良好。短期临床疗效可接受。对于根管治疗失败的病例，当由于相邻重要解剖结构而无法建立根尖手术通道时，IR 可作为一种可接受的牙髓治疗程序。关键词：根管治疗失败、桩核冠、根管再治疗、意 外 再 植。
