摘要/Abstract

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。

Abstract:

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.

Key words: intentional replantation, mandibular second molar, disease after root canal treatment
