The purpose of this investigation was to identify any difference of vertical dimension change that could be attributed to not using a face-bow transfer. Both demonstrations resulted in occlusal changes in vertical dimension. In comparing the demonstrations, where a hinge axis transfer was not taken, a greater amount of change was recorded over that observer in the demonstration where the hinge axis transfer was made. More dedicated research is clearly warranted to establish how much of the change was due to normal technical error. The time spent taking a face-bow transfer (hinge axis) may represent a small portion of the time required to accomplish adjustments on a denture where no transfer was performed. This information will allow the clinician to decide on the time they are willing to dedicate to occlusal corrections at the chair.
本研究的目的是确定垂直维度变化中可能归因于未使用面弓转移的任何差异。两次演示均导致垂直维度的咬合变化。在比较演示时，未进行铰链轴转移的演示中记录到的变化量比进行铰链轴转移的演示中的观察者记录到的变化量更大。显然需要进行更专门的研究来确定这种变化中有多少是由于正常的技术误差。花费在进行面弓转移（铰链轴）上的时间可能只占在未进行转移的义齿上完成调整所需时间的一小部分。这些信息将使临床医生能够决定他们愿意在椅旁花费多少时间进行咬合矫正。
