摘　　要：目的:探讨用Jasper Jumper矫治器矫治骨性下颌后缩病例,观察随着颌牙合关系的改变,口腔功能间隙面积的变化情况。方法:选择30例骨性下颌后缩病例,用Jasper Jumper矫治器引导下颌向前,采用治疗前后自身对照,观察口腔功能间隙面积的改变以及舌骨位置的变化。结果:Jasper Jumper矫治器治疗前后口腔功能间隙面积平均增加14.62 mm2,治疗前后比较有显著性差异。对照组口腔功能间隙面积平均增加了1.07 mm2,无显著性差异;Jasper Jumper矫治器治疗前后,舌骨距FH平面的水平距平均减小4.92 mm(P<0.05),舌骨距FH平面的垂直距平均增大5.79 mm(P<0.05)。对照组无明显变化。结论:Jasper Jumper矫治器矫治骨性下颌后缩可使口腔功能间隙明显增大,有利于上下颌骨、齿槽骨的发育及口颌系统功能的完善。Objective： To study Changes of oral functional space on skeletal mandibular retrusion patients used Jasper Jumper appliance. Method： 30 early skeletal mandibular retrusion patients were treated by Jasper Jumper appliance for 6-8 months. All patients were made cephalometric radiograph pre and post treatment. Oral functional space and position of hyoid were observed and measured. Result：Jasper Jumper appliance therapy brought about a 14.62 mm^2 increase in oral functional space; Hyoid was moved forward 4.92 mm and inferior 5.79 mm respectively. Conclusion： It showed that Jasper Jumper appliance treatment on skeletal mandibular retrusion patients was beneficial to increase oral functional space and to improve the jaw growth and the function of oral system.
