OSAHS患者戴用自行调节式口腔矫治器下颌骨位置变化的研究
【摘要】
目的：为下颌前伸式口腔矫治器治疗阻塞性睡眠呼吸暂停低通气综合征OSAHS（obstructive sleep apnea hypopnea syndrome）的下颌定位提供参考。
方法：采用X线头影测量32例患者戴用自行调节式口腔矫治器于治疗前、医师经验位及患者调节位时下颌水平与垂直测量项目的具体数据，并进行统计学处理。
结果：医师经验位和患者调节位与治疗前比较时，测量项目均有显著性差异；医师经验位和患者调节位比较时，除S-Ar-Go和H-MP测量数据差异无统计学意义（P值分别为0.95、0.843），其他测量项目均有显著性差异（P<0.05）。
结论：自行调节式口腔矫治器的医师经验位和患者调节位的下颌位置存在显著性差异，可为下颌前伸类口腔矫治器个性化治疗的下颌前伸定位研究提供参考。

Study on the position change of mandible in OSAHS patients cured by self-adjustable oral appliances(https://www.daowen.com)
Abstract
Objective：To provide a theoretic reference for mandibular positioning in the treatment of OSAHS with the mandibular advancement devices.
Methods：Thirty-two OSAHS patients detected to be valid by polysomnography were selected as research subjects.Cephalometric analysis was carried out to compare the position changes of mandibular in original position，physician experience position and patient self-adjustable position respectively.
Results：There is significant difference between physician experience position and patient self-adjustable position except S-Ar-Go and H-MP（P＜0.05）.
Conclusion：The great difference between two positions（physician experience position and patient self-adjustable position）may provide an individualized mandibular position for the treatment of mandibular advancement devices。
