By means of a variable capacitance device, the occlusal movements of 12 fully-developed teeth were recorded in 6 adult monkeys. Sustained extrusion was seen, with rhythmic pulsations due to the heart beat and to breathing. Extrusion varied from 10 to 138 micrometers over periods of 40-360 min, and became progressively slower with time. Because of the protracted nature of the extrusion, it is probable that these tooth movements were caused by forces generated in the periodontal ligament resulting from biochemical changes in the periodontium rather than by vascular alterations, and occurred as a result of the removal of intrusive loads from the opposing teeth.
通过一个可变电容装置，在6只成年猴子身上记录了12颗完全发育牙齿的咬合运动。观察到持续的牙齿伸长，伴有因心跳和呼吸产生的节律性脉动。在40 - 360分钟的时间段内，牙齿伸长幅度在10至138微米之间，并且随着时间的推移逐渐变慢。由于这种伸长具有持续性，这些牙齿运动很可能是由牙周组织生化变化导致牙周韧带产生的力引起的，而非血管改变所致，并且是由于对颌牙齿的侵入性负荷去除而发生的。
