摘　　要：当根管再治疗和根尖手术难以治疗根尖周病损时,意向性牙再植成为保留天然牙的另一种可选择的临床技术。本文报道1例28岁女性,主诉左下颌第二磨牙3个月前接受根管治疗后出现咀嚼不适,既往病史及影像学检查显示下颌第二磨牙为C形根管系统且根管充填致密,牙根C形凹槽中份出现透射影,近中根管壁和远中根管壁菲薄,该病例采用意向性牙再植治疗,18个月随访结果提示,意向性牙再植和纳米生物材料的应用促进了感染控制、牙齿保留和牙周组织再生。When the use of root canal retreatment and apical surgery experiences difficulty in treating endodontic diseases,intentional replantation is an optional clinical technique used to retain the tooth.A 28-year-old female complained of chewing discomfort at the mandibular second molar after undergoing root canal treatment 3 month ago.History record and radiographic examination revealed that a C-shaped root canal system was filled with gutta-percha in the mandibular second molar.A radiolucency area existed at the root furcal area with a thin canal wall in the distal and mesial roots.Intentional replantation was used to treat this tooth.The clinical and radiographic results showed that intentional replantation and nano-biomaterial application facilitated infection control,tooth retention,and periodontal tissue regeneration.
