A study was conducted that compared three arbitrarily located axes to the true hinge axis location on ten subjects. Of the 60 different arbitrary axis locations registered, 55% were within 6 mm of the true hinge axis. The results of this study revealed very small differences between a hinge axis face-bow. Hanau 132-SM face-bow, and the Whip-Mix ear face-bow. A linear deviation range of 0.116 to 0.268 mm is of doubtful clinical significance to complete denture construction. If an articulator like the New Simplex is used without a face-bow and with a 3 mm interocclusal wax record, it can be anticipated that there will be a 1 mm deviation in the anterior direction in centric occlusion. This discrepancy, incorporated with errors due to processing, can be eliminated by remounting the finished complete dentures with a new centric relation record for occlusal correction.
进行了一项研究，该研究将十个受试者的三个任意定位轴与真正的铰链轴位置进行了比较。在记录的60个不同的任意轴位置中，55%在距真正铰链轴6毫米范围内。该研究结果显示，铰链轴面弓、Hanau 132-SM面弓和Whip-Mix耳面弓之间的差异非常小。0.116至0.268毫米的线性偏差范围对于全口义齿的制作而言，其临床意义存疑。如果使用像New Simplex这样的牙合架，不使用面弓且采用3毫米的牙合间蜡记录，可以预期在正中咬合时向前会有1毫米的偏差。这种差异，再加上加工过程中的误差，可以通过用新的正中关系记录重新安装完成的全口义齿以进行咬合校正来消除。
