OBJECTIVE
Valid and reliable recording is a key requirement for accurately simulating individual jaw movements.
METHODS
Horizontal condylar inclination (HCI) and Bennett's angle were measured using a digital jaw tracker (Cadiax® Compact 2) in 27 young adults. Three mounting methods (paraocclusal tray adapter, periocclusal tray adapter, and tray adapter with mandibular clamp) were tested.
RESULTS
The mean values of the HCI differed by up to 10° between the mounting methods; however, the values for Bennett's angle did not differ substantially. While the intersession reliability of the Bennett's angle assessment did not depend on the mounting method, the reliability of the HCI assessment was only fair to good for the paraocclusal mounting method but poor for both periocclusal mounting methods.
DISCUSSION
For attaching the tracing bow of jaw trackers to the mandible, a paraocclusal tray adapter should be applied, to achieve the most reliable results.
目的
有效且可靠的记录是准确模拟个体颌运动的关键要求。
方法
使用数字颌追踪器（Cadiax® Compact 2）对27名年轻成年人测量水平髁突倾斜度（HCI）和贝内特角。测试了三种安装方法（咬合面托盘适配器、近咬合面托盘适配器和带下颌夹的托盘适配器）。
结果
不同安装方法之间HCI的平均值相差高达10°；然而，贝内特角的值没有显著差异。虽然贝内特角评估的组间可靠性不取决于安装方法，但HCI评估的可靠性对于咬合面安装方法仅为一般到良好，而对于两种近咬合面安装方法则较差。
讨论
为了将颌追踪器的描记弓连接到下颌骨上，应使用咬合面托盘适配器，以获得最可靠的结果。
