BACKGROUND
In the present paper, the authors analyze the effect of the "Swallowing Occlusal Contact Intercept Appliance" (SOCIA) in treatment of children with hyperdivergent Class II malocclusion. This functional appliance has no intra-oral anchorage, but induces a continuous periodontal, muscular, and articular stimulation.
METHODS
Twenty-six patients with hyperdivergent growth and class II malocclusion were selected and treated with SOCIA appliance. Cephalometric analysis was performed before treatment (T1) and immediately after the treatment (T2).
RESULTS
After 24 months treatment authors observed a modification of maxillary growth with a reduction of the divergence with an increase of the posterior facial height, a modification of condylar inclination and forward position of the a hyoid. No modifications was observed about the ANB angle. After treatment the open bite was resolved with a reduction of the inclination of the upper incisors.
CONCLUSIONS
SOCIA is a reliable functional appliance in growing age patients with a hyperdivergent pattern growth, anterior open bite and class II molar malocclusion.
背景
在本文中，作者分析了“吞咽咬合接触阻断矫治器”（SOCIA）对高角型安氏Ⅱ类错牙合儿童的治疗效果。这种功能性矫治器没有口内支抗，但能引起持续的牙周、肌肉和关节刺激。
方法
选取26例高角生长型和安氏Ⅱ类错牙合患者，采用SOCIA矫治器进行治疗。在治疗前（T1）和治疗后即刻（T2）进行头影测量分析。
结果
经过24个月的治疗，作者观察到上颌生长发生改变，发散度减小，面后部高度增加，髁突倾斜度和舌骨向前位置发生改变。ANB角未见改变。治疗后，前牙开牙合得以解决，上前牙倾斜度减小。
结论
对于生长发育期具有高角生长型、前牙开牙合和安氏Ⅱ类磨牙错牙合的患者，SOCIA是一种可靠的功能性矫治器。
