OBJECTIVE
To develop a computer-aided mandibular repositioning system (CAMRS) and investigate its preliminary application in efficacy prediction of oral appliance in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS).
METHODS
CAMRS was mainly consisting of a step motor and a screw that was remote-controlled by a computer. This system could work with polysomnography (PSG). Fourteen OSAHS patients diagnosed by PSG were recruited. With CAMRS, six mandibular positions were titrated with PSG for every hour.
RESULTS
Stable mandible positioning and little sleeping disturbance were observed. Apnea hypopnea index (AHI) was improved progressively with mandibular advancement. The extent of mandibular advancement was correlated with the severity of OSAHS (r = 0.72747).
CONCLUSIONS
CAMRS could reproductively and effectively reposition mandible with little sleeping disturbance. Through CAMRS, an individualized optimal mandibular position could be obtained for each OSAHS patient treated with oral appliance.
目的
研发一种计算机辅助下颌重新定位系统（CAMRS），并研究其在阻塞性睡眠呼吸暂停低通气综合征（OSAHS）患者口腔矫治器疗效预测中的初步应用。
方法
CAMRS主要由一个步进电机和一个由计算机远程控制的螺杆组成。该系统可与多导睡眠图（PSG）配合使用。招募了14例经PSG诊断的OSAHS患者。使用CAMRS，每小时用PSG对六个下颌位置进行滴定。
结果
观察到下颌定位稳定且睡眠干扰小。随着下颌前移，呼吸暂停低通气指数（AHI）逐渐改善。下颌前移程度与OSAHS严重程度相关（r = 0.72747）。
结论
CAMRS可以在睡眠干扰小的情况下重复且有效地重新定位下颌。通过CAMRS，可以为每位接受口腔矫治器治疗的OSAHS患者获得个性化的最佳下颌位置。
