摘要 目的比较Activator与Headgear-Activator的治疗作用,探讨两者的作用机理,并评价其临床应用的综合效果。方法选取36例安氏II类错牙合病例,12例采用Activator治疗,17例采用Headgear-Activator治疗,7例未经治疗作对照。分别摄取治疗前后(对照组采用1年时间间隔)X线头影侧位定位片,用同一参考系统定量分析两种治疗过程中发生的变化。结果两种治疗方法均能有效纠正II类错牙合,但作用机制不同。结论Activator和Headgear-Activator能有效调节上下颌骨发育的不协调,纠正儿童骨性II类错牙合。Headgear-Activator由于使用高位头帽,可以加强对上颌生长发育,特别是垂直方向的生长发育的控制;同时对牙齿牙槽产生作用,一定程度地控制Activator的一些不良反应,有利于患者牙颌面形态的充分改善及变化的表达。 Objective Compare the effects of Activator and Headgear-Activator on growing patients with Class II malocclusion.Methods The material consisted of36pairs of cephalograms,among which12cases were treated with Activator,17cases with Headgear-Activator and9cases without treatment for control.A reference grid was created to evaluate the skeletal and dental changes quantitatively.Results Activator and Headgear-Activator were effective on the correction of Class II malocclusion,but the mechanisms were different.Conclusion Both appliances were effective on the correction of skeletal Class II malocclusion of growing patients.By using the headgear,the inhabitation of forward and downward growth of the maxilla was enhanced,and the dental-alveolar changes different from Activator treatment benefit for the improvement of the dental facial appearance of the patient.
