In this study, a new jaw movement analyzer available with six degrees of freedom has been developed for unilateral cleft lip and palate patients. This new system does not need adaptors to connect devices inside and outside of the oral cavity, which interfere with a natural jaw movement, because it was organized on the basis of a magnetic motion capture system using an LC resonant marker. Moreover, the LC marker was small and had minimal circuit with no battery and could be driven wirelessly by action of electromagnetic induction.The system was composed of measurement instruments and coil assembly, consisting of a driving coil, LC markers, and a pick-up coil array. It was found that six degrees of freedom measurement and 60 Hz sampling cycles were achieved and the position accuracies of makers were within 1.0mm simultaneously using six LC resonant markers.This new system could capture six markers at the same with six degrees of freedom and drew a smooth path of jaw movement of cleft lip and palate patients. Furthermore the small magnetic markers in this system do not require any adaptors and allow us to measure the jaw movement under the natural conditions without obstruction. So, this system could be applied to young patients.

在这项研究中，一个新的颌骨运动分析仪可与六个自由度已被开发为单侧唇腭裂患者。这种新系统不需要适配器来连接口腔内外的设备，这会干扰自然的下颌运动，因为它是基于使用LC共振标记的磁性运动捕捉系统来组织的。该系统由测量仪器和线圈组件组成，线圈组件由驱动线圈、LC标记器和拾波线圈阵列组成。实验结果表明，该系统可实现6个自由度测量，采样周期为60Hz，同时使用6个LC谐振标记，标记位置精度在1.0mm以内，可同时捕获6个标记，为唇腭裂患者绘制出平滑的颌骨运动轨迹。此外，该系统中的小型磁性标记不需要任何适配器，允许我们在自然条件下无障碍地测量下颌运动。因此，该系统可以应用于年轻患者。
