目的：探讨颌骨骨折治疗后颌间弹性牵引对咬合关系恢复的影响。方法回顾分析192例上下颌骨骨折患者的临床资料，根据骨折情况及治疗方法确定是否应用颌间弹性牵引，分析未应用和应用颌间弹性牵引后咬合关系的恢复情况。结果本组192例患者中，颌骨骨折手术配合颌间牵引144例，咬合关系恢复良好140例，占97.2%；不良4例，占2.8%；术后未做颌间牵引48例，良好28例，占58.3%；不良20例，占41.7%。结论上下颌骨骨折术后，若配合颌间弹性牵引，能明显提高正常咬合关系及咀嚼功能的恢复。

Objective To explore the influence of intermaxillary elastic traction on the recovery of occlusal relationship after the treatment of jaw fracture. Methods The clinical data of 192 cases of upper and lower jaw fracture were retrospectively analyzed. Application of intermaxillary elastic traction was determined by fracture condition and treatment method. The recovery of occlusal relationship was analyzed in the cases with and the other cases without application of intermaxillary elastic traction. Results Among the 192 cases, there were 144 cases underwent jaw fracture operation combined with intermaxillary elastic traction. In these cases, there were 140 cases with good recovery of occlusal relationship (97.2%) and 4 cases with bad recovery (2.8%). There were 48 cases which did not received intermaxillary elastic traction, among them, there were 28 cases with good recovery (58.3%) and 20 cases with bad recovery (41.7%). Conclusion Intermaxillary elastic traction in coordination with jaw fracture operation can remarkably improve the recovery of occlusal relationship and masticatory function.
