OBJECTIVE
To assess the repeatability and kinematic data of Modjaw® recordings from a group of asymptomatic patients.
METHODS
Modjaw® mandibular kinematic data were recorded for 22 asymptomatic volunteers (DC/TMD questionnaire). Sagittal (SCI at 3 and 5 mm) and transversal (TCI at 4 mm) condylar inclination values of the instantaneous center of rotation were measured over two recording sessions. The repeatability of recordings was determined from the intraclass correlation coefficient (ICC), which is based on a one-way random-effects ANOVA.
RESULTS
The repeatability of recordings was found to be good to excellent. The mean TCI in mediotrusion was 7.1° ± 5.1, and the mean SCI in protrusion was 51.07° ± 9.43.
CONCLUSION
The Modjaw® device reliably records the patient's real hinge axis kinematics during functional mandibular movements. Data can be transferred with the patient's personal reference plane and digital casts to the CAD/CAM software.
目的
评估一组无症状患者的 Modjaw®记录的重复性和运动学数据。
方法
对 22 名无症状志愿者（DC/TMD 问卷）进行 Modjaw®下颌运动学数据记录。在两次记录过程中，测量瞬时旋转中心的矢状（SCI 在 3 和 5 毫米处）和横向（TCI 在 4 毫米处）髁突倾斜值。基于单因素随机效应方差分析的组内相关系数（ICC）来确定记录的可重复性。
结果
记录的重复性被认为是良好到优秀的。正中关系位时的平均 TCI 为 7.1°±5.1，前伸位时的平均 SCI 为 51.07°±9.43。
结论
Modjaw®设备可可靠地记录患者在功能性下颌运动过程中的真实铰链轴运动学。可以将数据与患者的个人参考平面和数字模型一起转移到 CAD/CAM 软件。
