Carriere Distalizer矫治器治疗安氏Ⅱ类骨性Ⅰ类错畸形的临床应用

Clinical application of Carriere Distalizer appliance in treating angle Class Ⅱ and skeletal class Ⅰ malocclusion

目的:观察Carriere Distalizer矫治器在安氏Ⅱ类骨性Ⅰ类错畸形患者前期治疗的应用效果。方法:选择安氏Ⅱ类骨性Ⅰ类错12例,上颌粘结Carriere distalizer矫治器,下颌双侧第一磨牙上放置附带固定舌弓的带环,颌间弹性Ⅱ类牵引拉双侧上颌磨牙远移。结果:经过1-6个月调整,12例患者平均每侧上颌磨牙远中移动3.68mm,建立稳定Ⅰ类磨牙关系。结论:通过高效、快速远中移动上颌磨牙,矫正磨牙关系,Carriere Distalizer矫治器为安氏Ⅱ类骨性Ⅰ类错非拔牙固定正畸治疗提供了可能。

Objective：To observe the clinical effects of Carriere Distalizer appliance in initial phase orthodontic treatment of angle Class Ⅱand skeletal class I malocclusion.Methods：12 Class Ⅱ malocclusion patients were selected as the subjects,Carriere Distalizer was placed on the maxillary first molar and the canine.The mandibular Arch was anchored by lower lingual arch and Class Ⅱ elastics were used.Results：After being used Carriere Distalizer appliance 1 to 6 months,occlusal relationship came back angle I and the maxillary first molar was distalized by 3.38mm per side on average.Conclusions：Carriere Distalizer appliance can distalize the maxillary first molars efficiently and correct the Class Ⅱ malocclusion.So it is most effective in treating Class Ⅱ malocclusion without extractions.
