In this case report, an alternative approach was presented for treatment of coronal fracture including pulp of maxillary central incisor, one of the abutments of an adhesive bridge, by using fiber post and tooth's own fractured component. The patient was referred to our clinic with the complaint of pain from the upper right central incisor and mobility of the adhesive bridge in maxillary anterior segment. It was realized that, the upper right central incisor, one of the abutments of the adhesive bridge, had been fractured at middle thirds of the crown including the pulp chamber. After dismounting the adhesive bridge and completion of the root canal treatment, a fiber post was placed into the fractured tooth. The fractured component, adherent to adhesive bridge retainer, was concorded to the fiber post. The whole structure was cemented with adhesive resin. A 1-mm-wide groove was made along the fracture line and restored with composite resin. The patient was evaluated clinically and radiographically at 12 and 30 months after the treatment.
Adhesive cementation of fractured component by supporting the remaining tooth structure with a fiber post is an inexpensive and conservative treatment alternative when the fractured component is compatible with the remaining tooth structure in cases of tooth fractures including the pulp chamber at anterior segment.
在本病例报告中，提出了一种替代方法来治疗上颌中切牙冠部骨折，包括牙髓和粘固桥的一个基牙，使用纤维桩和牙齿自身的折断部分。患者因右上中切牙疼痛和上颌前牙段粘固桥松动而到我们诊所就诊。发现上颌中切牙，即粘固桥的一个基牙，在冠部的中部三分之一处折断，包括牙髓腔。拆除粘固桥并完成根管治疗后，将纤维桩放置到折断的牙齿中。与纤维桩一致的是，粘固桥固位器上附着的折断部分。整个结构用粘固树脂粘固。沿着骨折线制作 1 毫米宽的槽并用复合树脂修复。治疗后 12 个月和 30 个月对患者进行临床和影像学评估。
当折断部分与前牙段牙髓腔的剩余牙齿结构相匹配时，用纤维桩支撑剩余牙齿结构，将折断部分粘固是一种经济且保守的治疗选择，适用于包括牙髓腔在内的前牙段牙齿折断的情况。
