A group of 19 patients where traumatic root fractures were treated with surgical extrusion procedure has been clinically and radiographically followed up for 10 years. Except for one out of 21 intraalveolar transplanted roots all functioned with different kinds of crown restorations and without pathological complications. The surgical extrusion method should thus be a useful tool in the treatment of teeth with cervical root-fractures and also teeth with deep cervical root caries which are difficult to treat conservatively.
一组19例采用外科挤出术治疗外伤性牙根折断的患者已进行了10年的临床和影像学随访。除21颗牙槽内移植牙根中有1颗外，其余所有牙根均通过不同类型的冠修复发挥功能，且无病理并发症。因此，外科挤出术应是治疗颈段牙根折断牙齿以及保守治疗困难的颈段深龋牙齿的一种有用方法。
