The correct orientation of the occlusal plane is the first and one of the important steps while recording jaw relationships in an edentulous patient. One of the most popular methods is to orient the occlusal plane to interpupillary line anteriorly and ala-tragus lines posteriorly which is usually accomplished by repetitive adjustment of the maxillary rim until a hand-held Fox's plane appears to be parallel to these lines. However, this process is time-consuming and error-prone. The eventual plane is almost always an educated guess, and this can be difficult for a new student. The device presented in this article marks the occlusal plane on wax rims parallel to interpupillary line anteriorly and the ala-tragus lines posteriorly, and thus, occlusal plane can be oriented in one simple step, thereby saving time and increasing efficiency of the operator.
在为无牙颌患者记录颌关系时，咬合平面的正确定位是首要且重要的步骤之一。最常用的方法之一是使咬合平面在前方与瞳孔连线对齐，在后方与鼻翼 - 耳屏线对齐，这通常需要反复调整上颌基托，直到手持的福克斯平面似乎与这些线平行。然而，这个过程既耗时又容易出错。最终的平面几乎总是凭经验猜测，这对新手学生来说可能很困难。本文介绍的装置可在蜡基托上标记出与前方瞳孔连线和后方鼻翼 - 耳屏线平行的咬合平面，因此，咬合平面可以通过一个简单步骤来定位，从而节省时间并提高操作者的效率。
