摘　　要：目的 :探讨快速扩弓结合方丝弓技术及前方牵引装置治疗骨性Ⅲ类错的方法和特点。方法 :选择 15例骨性Ⅲ类错患儿 ,男 6例 ,女 9例 ,年龄 8 5～ 12岁 ,均为替牙期。X线片显示主要为上颌骨发育不足。左手腕骨片显示为生长发育的高峰前期。结果 :15例患者经平均 9月的治疗 ,面型均明显改善 ,头影测量其骨骼改变主要为SNA角增大 ,A点前移。结论Objective:The skeletal Class Ⅲ malocclusion often occurs in ethnic Asia population, and it is difficult to obtain an ideal results if only treated with protraction headgear (PH). However, the combined rapid palatal expansion (RPE), Edgewise Technique and PH can reach it, so the authors investigated the methods and characteristics of combined RPE, Edgewise Technique and PH in the treatment of skeletal Class Ⅲ malocclusion.Methods: Fifteen patients, aged 8.5～12 years, including six males and 9 females, with skeletal Class Ⅲ malocclusion and maxillary retrusion were selected for this study. Radiographs of left hand and wrist showed that all patients were at the pre-pubertal stage. The duration of treatment was nine months on average.Results: The SNA and A-ptm increased with a mean of cephalometric analysis, which showed significant difference (P<0.05).Conclusion: Obvious skeletal and profile changes can be achieved with combined RPE, Edgewise Technique and PH in the treatment of early skeletal Class Ⅲ malocclusion.
