This paper describes a novel technique of directly measuring loads at the condyle in Macaca arctoides and provides recordings on one animal while measuring loads at the TMJ. This study is the first to actually measure loads directly at the articulating surfaces of the condyle. The data collected in this study confirm Hylander's data that the TMJ is a stress-bearing joint. With this pilot study, observations which can be made are: 1) The loads at the condyle are minimal during posterior chewing of both soft and hard foods (1-3 lb), and 2) during mastication of food the load (3-4 lb) at the condyle is larger than for posterior chewing. It was demonstrated during the calibration of the transducer that as the condyle translates forward over the articulating eminence during opening, a load is produced on it which is as large as the load present during incisal biting. Since recordings were only successfully taken on one animal, the above observations must be confirmed with further experiments.
本文描述了一种直接测量熊猴髁突负荷的新技术，并在测量颞下颌关节负荷时对一只动物进行了记录。本研究首次实际直接测量髁突关节表面的负荷。本研究收集的数据证实了海兰德的数据，即颞下颌关节是一个承重关节。通过这项初步研究，可以得出以下观察结果：1）在咀嚼软食和硬食的后牙咀嚼过程中，髁突的负荷最小（1-3磅）；2）在咀嚼食物时，髁突的负荷（3-4磅）大于后牙咀嚼时的负荷。在传感器校准过程中发现，在开口时髁突向前越过关节结节平移时，其上产生的负荷与切牙咬合时的负荷一样大。由于仅在一只动物身上成功进行了记录，上述观察结果必须通过进一步实验加以证实。
