This case report presents the endodontic management of a horizontally fractured right incisor involving healing with granulation tissue using an intraradicular splinting technique. We also discuss the spontaneous healing of the fractured left central incisor with calcified tissue. A composite resin splint was made for all of the upper anterior teeth. The root canal of the right incisor was temporarily filled with calcium hydroxide slurry. The intraradicular splinting involved placing a file in the canal. Sealer was introduced into the canal and then a no. 110 K file was fixed in the canal with polycarboxylate cement. The tooth was asymptomatic and the composite splint was removed after 1 month. The right incisor appeared normal clinically and radiographically at the 30-month recall. This case demonstrates that intraradicular splinting can be used to manage horizontally fractured teeth with necrotic and mobile coronal segment.
本病例报告介绍了一例右侧中切牙水平折断的根管治疗，采用根管内夹板固定技术，通过肉芽组织实现愈合。我们还讨论了左侧中切牙折断后钙化组织的自发愈合情况。为所有上前牙制作了复合树脂夹板。右侧中切牙的根管临时用氢氧化钙糊剂充填。根管内夹板固定是在根管内放置一根锉。将封闭剂导入根管，然后用聚羧酸锌水门汀将110号K锉固定在根管内。患牙无症状，1个月后拆除复合夹板。在30个月的复查时，右侧中切牙在临床和影像学上均表现正常。本病例表明，根管内夹板固定可用于治疗冠部坏死且松动的水平折断牙。
