Abstract

This study aimed to clinically evaluate the survivability of surgically extruded teeth, to assess the success rate and predictable factors pertaining to alterations in both hard and soft tissues adjacent to extruded teeth. A total of 46 complicated crown‐root fractured maxillary central and lateral incisors with >75% tooth structure loss relatively due to trauma were included. Preoperative clinical and radiographic variables were recorded. Single operator performed endodontic treatment before surgical extrusion. Patients were recalled for review at 6, 12, 18, 24 and 36 months. Survivability was assessed using Kaplan–Meier survival analysis. With a mean follow‐up of 2.8 years, survival rate was 95.7%. Mobility observed in only two cases. The crown‐root ratio was favourable (1:2) in all the cases except for five teeth. Only two teeth displayed non‐progressive root resorption. Survival of surgically extruded teeth relies on significant predictors like favourability of CRR and implementation of atraumatic extrusion.

手术挤压治疗复杂牙冠-牙根骨折上颌切牙的存活率评估：临床研究

本研究旨在临床评估手术挤压牙齿的存活率，评估成功率以及与挤压牙齿邻近软硬组织改变相关的可预测因素。本研究共纳入了46颗复杂的牙冠-牙根折断的上颌中切牙和侧切牙，其中75%的牙齿结构损失是由外伤造成的。记录术前临床和放射学变量。手术挤压前，由单一操作者进行牙髓治疗。分别在 6、12、18、24 和 36 个月时对患者进行复查。采用卡普兰-米尔生存分析法评估存活率。平均随访时间为 2.8 年，存活率为 95.7%。仅在两个病例中观察到移动性。除五颗牙齿外，其他所有病例的牙冠与牙根的比例都很理想（1:2）。只有两颗牙齿显示出非进行性牙根吸收。手术挤压牙齿的存活率取决于一些重要的预测因素，如 CRR 的良好性和非创伤性挤压的实施。

期刊介绍： The Australian Endodontic Journal provides a forum for communication in the different fields that encompass endodontics for all specialists and dentists with an interest in the morphology, physiology, and pathology of the human tooth, in particular the dental pulp, root and peri-radicular tissues. The Journal features regular clinical updates, research reports and case reports from authors worldwide, and also publishes meeting abstracts, society news and historical endodontic glimpses. The Australian Endodontic Journal is a publication for dentists in general and specialist practice devoted solely to endodontics. It aims to promote communication in the different fields that encompass endodontics for those dentists who have a special interest in endodontics.
