摘　　要：目的：观察Tip—Edge Plus矫治技术治疗双颌前突畸形的临床效果，并对其机制进行探讨。方法：对20例双颌前突畸形患者采用Tip—Edge Plus矫治技术治疗，所有病例均拔除4个第一双尖牙。通过对患者治疗前后相关的头影测量项目进行统计分析，评价其治疗效果。结果：20例患者平均疗程为18个月，治疗后其覆牙合、覆盖及磨牙关系均在正常范围。相关的头影测量项目分析显示患者治疗后侧貌得到了明显改善，硬组织相关头影测量结果中SNA、SNB、U1～L1角等变化均有显著差异（P〈0．01）；而软组织相关头影测量结果中鼻唇角平均增加了12°，Z角平均增加了7．26°，其他各项软组织指标也均有改变（P〈0．01）。结论：Tip—Edge技术能快速、高效地矫正双颌前突畸形。Objective：To observe the clinical effects of Tip-Edge Plus appliance in treating bimaxillary protrusion patients and discuss its mechanics. Methods：20 patients with bimaxillary protrusion were treated with Tip-Edge Plus appliance. 4 premolars in all those cases were extracted. The results of cephalometric measurements of pretreatment and posttreatment were statistically analyzed to evaluate orthodontic effects. Results：20 patients received an average of 18 months of treatment,after treatment dental coverage and molar relations of these patients were in the normal range. Analysis of related projects cephalometric showed that patients with lateral outlook improved significantly,SNA,SNB and U1-L1 angle changes in hard tissue with significant difference in cephalometric measurements（P〈0.01 ）. Soft tissue Cephalometric related nose angle measurements showed an average increase of 12° ;Z increased by an average angle of 7.26° ,and other indicators in soft tissue also improved （P〈0.01）. Conclusion：Tip-Edge Plus technology can quickly and efficiently correct bimaxillary protrusion deformity.
