目的 应用口内上颌前方牵引器辅助治疗安氏Ⅲ类错(牙合)畸形,并与传统的面具式上颌前方牵引进行对比,以探讨口内前方牵引器在安氏Ⅲ类患者早期矫形治疗中的作用.方法 选择20名安氏Ⅲ类患者,首先戴用上颌扩弓器以周期性扩缩方式行快速扩弓7周,然后将患者分为2组.组1(10人)戴用牙支持式口内前方牵引器直至前牙反(牙合)解除,继以夜间戴用面具式前方牵引;组2(10人)直接戴用上颌前方牵引面具,要求每天至少戴用14小时.平均观察10个月.结果 两组患者治疗后ANB和覆盖均有明显改善,且口内前方牵引器治疗组较单纯面具式前方牵引组改善程度为著(P<0.05).反(牙合)解除时间组1(平均2.3个月)较组2(平均7.8个月)显著为快(P<0.001).结论 辅助应用口内前方牵引器能有效地矫形治疗骨性安氏Ⅲ类错(牙合).
目的 應用口內上頜前方牽引器輔助治療安氏Ⅲ類錯(牙閤)畸形,併與傳統的麵具式上頜前方牽引進行對比,以探討口內前方牽引器在安氏Ⅲ類患者早期矯形治療中的作用.方法 選擇20名安氏Ⅲ類患者,首先戴用上頜擴弓器以週期性擴縮方式行快速擴弓7週,然後將患者分為2組.組1(10人)戴用牙支持式口內前方牽引器直至前牙反(牙閤)解除,繼以夜間戴用麵具式前方牽引;組2(10人)直接戴用上頜前方牽引麵具,要求每天至少戴用14小時.平均觀察10箇月.結果 兩組患者治療後ANB和覆蓋均有明顯改善,且口內前方牽引器治療組較單純麵具式前方牽引組改善程度為著(P<0.05).反(牙閤)解除時間組1(平均2.3箇月)較組2(平均7.8箇月)顯著為快(P<0.001).結論 輔助應用口內前方牽引器能有效地矯形治療骨性安氏Ⅲ類錯(牙閤).

Objective The aim of this study was to evaluate the skeletal and dentoalveolar changes achieved by a tooth-borne maxillary protractor in growing skeletal and dental Class Ⅲ patients and to compare these changes with maxillary protraction face mask group.Methods Twenty patients were selected and treated with repetitive rapid palatal expansion and constriction for 7 weeks.The patients were divided into two groups according to the treatment type:the intra-oral protractor group (mean age 10.12± 1.81 years,n=10) and the Delaire type maxillary protraction group (mean age 11.02±1.08 years,n=10).In group one a tooth-borne maxillary protractor was used until anterior crossbite was corrected and then followed by wearing face mask protraction at night time.In group two,maxillary protraction face mask was required to wear at least 14 hours/day.Results Significant changes in ANB and overjet were noted in the both groups and demonstrated the effects of the appliances in the treatment of Class Ⅲ malocclusions.In comparing the two groups,the improvements were greater in the intra-oral protractor group (P<0.05).The duration for the correction of crossbite was reduced significantly in group one (2.3 months on average) than that in group two (8.6 months on average,P<0.001).Conclusions The combination use of an intra-oral protractor is effective for correction of skeletal Class Ⅲ malocclusion.
