Load deformation studies were carried out on the maxillary arches of three adult Macaca irus monkeys using tooth-borne and tissue-borne plates. By means of an electronically controlled dynamometer, forces with different loading rates, creep, and simulated chewing loads were applied to the plates. The displacement was measured electronically relative to posterior teeth using a linear variable displacement transducer. The six main viscoelastic features noted by other workers for individual teeth under load have been confirmed for the test plates and can be attributed to the connective tissues in the periodontium and in the mucosa. The magnitude of displacement of the tissue-borne plate, however, was appreciably greater than for the tooth-borne plate, and the recovery was far slower. Reducing the part of the plate in contact with mucosa produced greater intrusion, and reducing the number of teeth supporting the tooth-borne plate produced greater displacement.
使用牙支持式和组织支持式托板，对三只成年食蟹猴的上颌牙弓进行了加载变形研究。通过电子控制测力计，对托板施加不同加载速率、蠕变和模拟咀嚼负荷的力。使用线性可变位移传感器相对于后牙以电子方式测量位移。其他研究人员所指出的单个牙齿在负载下的六个主要粘弹性特征，在测试托板中得到了证实，并且可归因于牙周膜和黏膜中的结缔组织。然而，组织支持式托板的位移幅度明显大于牙支持式托板，并且恢复要慢得多。减少托板与黏膜接触的部分会产生更大的侵入，减少支持牙支持式托板的牙齿数量会产生更大的位移。
