Abstract

The effects of different sites of an expansile force on the maxillae of three monkeys were studied. A lateral force of five pounds was delivered directly to four locations on each maxilla. Aluminum rods, rigidly attached to the teeth of each buccal segment, were photographed before and after each force application. The data indicated that the pattern of lateral maxillary displacement is related to the position of the lateral force in relation to the center of resistance of each maxilla.

摘要

研究了扩张力的不同作用部位对三只猴子上颌骨的影响。对每只上颌骨的四个位置直接施加五磅的侧向力。在每次施加力之前和之后,拍摄牢固连接到每个颊侧牙段牙齿上的铝棒。数据表明,上颌骨侧向移位的模式与侧向力相对于每个上颌骨阻力中心的位置有关。
