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Ó类错的方法和特点。方法:选择15例骨性Ó类错患儿,男6例,女9例,年龄815~12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:三者联合治疗骨性Ó类错可取得明显的骨骼及侧貌改变。

Abstract:

Objective:The skeletal ClassÓmalocclusion often occurs in ethnic Asia population, and it is difficult to obtain an ideal re- sults if only treatedwith protraction headgear (PH). However, the combined rapid palatal expansion (RPE), Edgewise Technique and PHcan reach it, so the authors investigated the methods and characteristics of combined RPE, Edgewise Technique and PHin the treatment of skeletal ClassÓmalocclusion.Methods:Fifteen patients, aged 8.5~12 years, including six males and 9 fe- males, with skeletal ClassÓmalocclusion and maxillary retrusionwere selected for this study. Radiographs of left hand and wrist showed that all patients were at the pre-pubertal stage. The duration of treatmentwas 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:Obvi- ous skeletal and profile changes can be achievedwith combined RPE, Edgewise Technique and PHin the treatmentof early skele- tal ClassÓmalocclusion.
