本研究的目的是探讨一个最佳的条件下，轻敲运动咬合注册。用六自由度下颌运动记录系统测量了5名正常人在不同头位等不同条件下叩击时起始点和髁突轨迹点的闭合轨迹（Camper平面，法兰克福平面;平行于地板），敲击频率（2 Hz，3 Hz）和切缘间距（20 mm，30 mm）。通过绘制两个跟踪点，在其上观察到几乎纯下颌旋转。结果：当头部位于Camper平面上，敲击频率为3 Hz，切距为30 mm时，旋转值最大;在最后髁稳定位记录的下颌骨最后闭合路径不会引起髁突的后移，因此，使用最后闭合路径可以获得可靠的咬合记录当满足上述攻丝条件时，以下颌骨的长度作为参考。
The purpose of this study was to investigate an optimum condition for tapping movements for bite registration. The closing path of inicisal and condylar tracking points were measured with a system for recording jaw movements in 6 degrees of freedom during tapping mevements in five normal subjects under various conditions such as different head positions (Camper plane, Frankfort plane; parallel to the floor), tapping frequency (2 Hz, 3 Hz), and interincisal distance (20 mm, 30 mm).The most stable position of the condyle was found by plotting both tracking points, on which almost pure mandibular rotation was observed. Each tapping condition was evaluated by comparing the incisal path's range of rotation of the vertical component, which was termed the rotation value of the mandible.Results: When the head was positioned on the Camper plane, with a 3 Hz tapping frequency at a interincisal distance of 30 mm, the highest rotation value was found ; the most posterior closing path of the mandible recorded at the most condylar stable position did not cause posterior displacement of the condyle.It is concluded that a reliable bite registration can be obtained by using the most posterior closing path of the mandible as reference when the above mentioned tapping conditions are met.
