It has been recognized for many years that muscle function influences bone formation and morphology. It is hypothesized here that the movement of bone into new positions within a muscle system results in rearrangement of the stress distribution and reorganization of shape and internal structure. To test the above hypothesis, clinical and animal experiments involving the use of posterior occlusal bite blocks, Herbst appliances, and temporal and masseter muscle stimulation were undertaken. Chronic or continuous alteration in mandibular position within the neuromuscular environment with the posterior occlusal bite block and the Herbst appliance in a sample of monkeys produced extensive condylar remodeling and change in mandibular size. Short periods of induced hyperactivity in the masseter and temporal muscles were associated with the production of malocclusion symptoms. Excess induced temporal muscle activity of specific frequency and intensity may interfere with the remodeling of bone grafts placed under the temporal muscle, while a lesser level of activity was associated with bone remodeling.
多年来人们已经认识到肌肉功能会影响骨骼的形成和形态。本文提出的假设是，骨骼在肌肉系统内移动到新位置会导致应力分布重新排列以及形状和内部结构的重新组织。为了验证上述假设，开展了涉及使用后牙咬合块、Herbst矫治器以及颞肌和咬肌刺激的临床和动物实验。在一组猴子样本中，使用后牙咬合块和Herbst矫治器在神经肌肉环境中使下颌位置发生慢性或持续性改变，导致髁突广泛重塑以及下颌大小改变。咬肌和颞肌短时间的诱导性活动亢进与错牙合症状的产生有关。特定频率和强度的诱导性颞肌活动过度可能会干扰置于颞肌下方的骨移植的重塑，而较低水平的活动则与骨重塑有关。
