合垫配合颌间牵引治疗儿童髁突骨折的临床研究

Clinical research of using occlusal splint withintermaxillary traction in condylar fractures of children

目的探讨后牙区合垫配合前牙区颌间牵引治疗儿童髁状突骨折的临床效果。方法选取2016年12月至2018年2月大理大学第一附属医院口腔颌面外科收治的替牙期11例髁状突骨折患儿,年龄7~14岁。根据年龄、骨折类型制作不同厚度的后牙区合垫,前牙区植入种植体支抗进行颌间牵引3周,3周后停止颌间牵引,合垫戴用3个月,配合早期功能锻炼。治疗后1、3、6、12个月进行随访复查。结果11例髁突骨折患儿形态和功能均恢复良好;CT影像显示髁状突骨折处改建良好,双侧基本对称,升支高度基本一致。结论合垫配合前牙区颌间牵引治疗儿童髁状突的临床疗效显著,是一种有效的保守治疗方法。

Objective To evaluate the clinical outcome of molar teeth occlusal splint with intermaxillary traction in condylar fractures of children.Methods From December 2016 to February 2018,11 cases children with condylar fracture in mixed dentition stage were selected from the Department of Oral and Maxillofacial Surgery,the First Affiliated Hospital of Dali University,aged 7-14 years.According to the age and fracture type,the posterior occlusal pad with different thickness was made.Implant anchorage was implanted in the anterior area for 3 weeks.After 3 weeks,intermaxillary traction was stopped.The splint was worn for 3 months,and early functional exercise was carried out.The patients were followed up 1,3,6 and 12 months after treatment.Results All the patients showed clinically satisfactory results,along with unimpaired function and normal growth and development of the mandible.The CT images showed remodelling and reconstruction of the fractured condylars,the two sides are symmetrical,at the same in vertical height of ramus.Conclusion The clinical effect of splint combined with intermaxillary traction in the treatment of children's condyle is significant,which is an effective conservative treatment.
