摘要：

目的 观察纤维根管桩根管内固定联合复合树脂粘接对儿童前牙冠根联合折的修复效果。方法 上颌中切牙外伤致冠根联合折断的患者11例（患牙11颗），年龄11~14岁，均为横折或斜折，无纵折，无牙槽骨骨折；就诊予以断牙外固定后即刻行一次性根管治疗，观察1周；采用纤维根管桩根管内固定加冠根断端复合树脂粘接的方法进行断端自体牙修复。结果 11颗患牙中，9例治疗成功，短期内恢复美观和功能，效果满意；失败2例，其中1例为腭侧折断，折断线较低，出血、渗出较多；另1例患儿未遵医嘱食用硬物导致折断面松动。结论 采用纤维根管桩根管内固定加复合树脂粘接治疗儿童前牙冠根联合折，操作简单、快捷，可在短期内恢复美观和功能，最大限度地减少牙体和牙周组织损失，是一种较为理想的过渡性修复方法。

Abstract:

Objective To investigate the clinical effect of fibrous root canal dowel internal fixation combined with composite resin adhesion in treatment of crown-root fracture of anterior teeth in children. Methods Eleven children (11 teeth) aged 11 to 14 with crown-root fracture caused by trauma of upper mandible medial incisor were selected. All were horizontal fracture or oblique fracture, and there was no longitudinal fracture and alveolar bone fracture. Patients received one-visit endodontics treatment after external fixation of the injured teeth, and were follow up for one week. The crown-root broken ends were restored with fibrous root canal dowel internal fixation combined with composite resin adhesion. Results Nine teeth were successfully restored, and were cosmetically and functionally resumed in short term. One patient failed due to lower palatal fracture line, with more wound hemorrhage and exudation. And the other patient failed due to consumption of hard food, which led to the loose broken ends. Conclusion Fibrous root canal dowel internal fixation combined with composite resin adhesion may be an ideal temporary restoration method in treatment of crown-root fracture of anterior teeth in children, which can resume cosmetics and function in short term and decrease loss in dental and periodontal tissues to the full extent.
