这种印记（咀嚼“肌肉记忆”）被证明是一种条件反射，其肌肉条件反射持续不到两分钟，比之前认为的要短得多。这种反射在每次吞咽时被强化并储存在咀嚼肌中，调节咀嚼肌的活动，引导下弓准确地进入内压区。这些肌肉调节补偿了不断变化的影响下颌骨进入ICP的内部和外部因素。本文中描述的一个简单的快速实验分离了印痕，使读者第一次清楚地看到它的作用。我们强烈建议每个读者都做这个实验。这个实验表明，通过隐藏咀嚼肌肉的反应（撞击-滑动），印痕如何限制了治疗师在实现咬合-肌肉相容性方面的成功。这一发现具有重要的临床意义。这意味着，就治疗咬合的肌肉方面而言，牙医传统上治疗咬合是盲目的，这是咬合思想的神经肌肉学派试图纠正的情况。关于遮挡的争论仍在继续。
The engram (the masticatory "muscle memory") is shown to be a conditionable reflex whose muscle conditioning lasts less than two minutes, far shorter than previously thought. This reflex, reinforced and stored in the masticatory muscles at every swallow, adjusts masticatory muscle activity to guide the lower arch unerringly into its ICP. These muscle adjustments compensate for the continually changing internal and external factors that affect the mandible's entry into the ICP. A simple quick experiment described in this article isolates the engram, enabling the reader to see its action clearly for the first time. It is urged that every reader perform this experiment. This experiment shows how the engram, by hiding the masticatory muscles' reaction (the hit-and-slide), limits the success of the therapist in achieving occlusion-muscle compatibility. This finding has major clinical implications. It means that, as regards the muscle aspect of treating occlusion, the dentist treating occlusion conventionally is working blind, a situation the neuromuscular school of occlusal thought seeks to correct. The controversy over occlusion continues.
