摘要

在这项研究中,8个浸泡过的人类儿童头骨(牙龄约9.5岁)被置于标准化的高拉力头套牵引系统中。对上颌骨施加每侧0.5 ~ 3.5 N (1 N = 0.1 kgf)的拉力。通过激光全息术在每个颅骨的22个指示点上确定骨骼部件的位移。在所有头骨中都建立了协调的位移和数量和方向的变化。总的位移量主要是单个颅骨的特征,而不是特定的位移。平均上颌向略向下后方向移位,几乎平行于咬合平面。未见骨骼部件变形。结果表明,上颌和其他骨骼构件的初始位移与受力方向不一致。

Initial displacements and variations of eight human child skulls owing to high-pull headgear traction determined with laser holography

In this study eight macerated, human child skulls (dental age approximately 9.5 years) were subjected to a standardized high-pull headgear traction system. Tensile forces from 0.5 to 3.5 N (1 N = 0.1 kgf) per side were produced to the maxillae. Displacements of skeletal components were determined at 22 indicator points per skull by means of laser holography. Coordinated displacements and variations in amount and direction were established in all skulls. The overall amount of displacements was primarily a characteristic of an individual skull, not of a particular displacement. On the average, the maxillae were displaced in a slightly downward and posterior direction almost parallel to the occlusal plane. No deformations of skeletal components were seen. Results indicated that initial displacements of the maxillae and other skeletal components are not in the same direction as the direction of applied forces.
