The aim of the present work was to evaluate the dentoskeletal effects of swallowing occlusal contact intercept appliance (SOCIA) III in pseudo Class III malocclusion treatment.
Thirty-six patients (mean age: 9.46 years old) with pseudo-Class III malocclusion and 22 pseudo-Class III untreated controls (mean age: 8.7 years old) were selected and examined. All patients presented with a cervical stage CS2, CS3, or CS4. Patients with CS5 were not enrolled in the study. Cephalometric analysis was performed before phase 1 treatment (T1) and immediately following phase 2 treatment (T2).
Paired t-test and independent t-test.
SOCIA III had skeletal and dental effects. The main effects of SOCIA III were on the midface with an effective increase of the sagittal growth (cranial base P < 0.001, anterior cranial base (ACB) P < 0.001, and maxilla growth P < 0.001) and vertical growth (anterior facial height P < 0.001). The effects of SOCIA on the mandible were a control of mandibular postrotation (P = 0.82) and the sagittal growth (P < 0.007). At the end of the treatment, a normal overjet was achieved (P < 0.001).
The SOCIA III effects are resumed as follow: (a) an effective maxillary sagittal increase on the sagittal plane; (b) a vertical mandibular control; (c) a resolution of overjet; (d) no increase of overbite; (e) a stimulation of ACB growth.
本研究旨在评估吞咽式咬合接触阻断矫治器（SOCIA）III对假性III类错牙合畸形治疗的牙颌面效应。
选取36例假性III类错牙合畸形患者（平均年龄9.46岁）和22例未经治疗的假性III类错牙合畸形对照者（平均年龄8.7岁）进行检查。所有患者均处于颈椎发育阶段CS2、CS3或CS4。处于CS5阶段的患者未纳入本研究。在1期治疗前（T1）和2期治疗后即刻（T2）进行头影测量分析。
配对t检验和独立t检验。
SOCIA III具有骨骼和牙齿效应。SOCIA III的主要效应在于中面部，矢状向生长有效增加（颅底P<0.001，前颅底（ACB）P<0.001，上颌生长P<0.001）以及垂直向生长（前面部高度P<0.001）。SOCIA对下颌骨的效应是控制下颌后旋（P = 0.82）和矢状向生长（P<0.007）。治疗结束时，实现了正常的覆盖（P<0.001）。
SOCIA III的效应总结如下：（a）矢状面上有效增加上颌矢状向；（b）垂直控制下颌骨；（c）解决覆盖问题；（d）覆牙合未增加；（e）刺激前颅底生长。
