| 目的：研究Splint 在纠正CR-CO不调时对下颌骨位置变化的影响，为正畸治疗前正确的诊断和治疗提供参考。方法：随机选
取门诊戴用Splint治疗的患者23 例，在其治疗前后拍摄头颅定位侧位片，应用Jarabak 分析法测量并进行统计学分析。结果：患者
戴用Splint治疗后，出现下颌后缩，面下1/3 变长；口内表现为前牙覆盖变大，覆牙合变浅或者开牙合，可见早接触点；前后头影测
量结果比较显示N-Go-Me 显著增加(P<0.05)，后面高/ 前面高、S-Ar-Go 和N-Go-Me 较治疗前显著减小(P<0.05)，N-S-Ar 和
Ar-Go-Me 治疗前后无明显差异(P>0.05)。结论：Splint 在纠正CR-CO不调时，同时改变了下颌骨的位置，使下颌骨发生顺时针方
向旋转。因此，在正畸治疗之前，应该充分考虑下颌骨可能发生的这种变化，以便更好的确定正畸治疗方案。 |

| Objective:To study the effect of Splint treatment on the position of mandibular in the correction of CR-CO discrepancy
and provide proper reference for correct orthodontic diagnosis and treatment of malocclusion.Methods:23 patients were selected randomly
among outpatients of Splint treatment. Cephalometrics were taken before and after treatment and Jarabak cephalometric analysis
was used to measure the differences during the treatment.Results:Mandibular was retracted after Splint treatment and the lower third part
of the face became longer. Overjet became deeper and the overbite became shallower(P<0.05). After Splint treatment, there was a smaller
S-Go/N-Me，Ar-Go-Nand S-Ar/Ar-Go (P<0.05). However, N-Go-Me after treatment was bigger than that of before treatment.Conclusion:When CR-CO discrepancy was corrected using Splint treatment, the position of mandibular was backwards and turned clockwise. And
this should be considered before orthodontic treatment and make a more stable and harmonious CR-CO relation. |
