正常的咬合运动依赖于牙、颌关节以及神经肌肉的功能协调。其中任何之一发生障碍都会导致整个口颌系统的功能紊乱。临床上对于咬合的诊断和咬合调整,一般采用咬合纸、蜡片等作咬合印记来检查咬合状态,这些方法只能检查咬合运动结束后的静止状态,由于缺乏时间这一要素,所以,不能直接观察到咬合开始至滑走时的动态接触关系。另外,把咬合纸、蜡片放入口内作检查时,容易引起生理咬合位置的变化,而且受唾液影响,所以,近年来开始采用咬合音来检查咬合状态。咬合音分析法就是上下牙的撞击或滑走产生的振动,通过骨传导或空气传导由传感 Normal bite movement depends on the coordination of teeth, jaw joints and neuromuscular function. Any one of the obstacles will lead to the entire oral mandibular system dysfunction. Clinically for the diagnosis of bite and bite adjustment, the general use of bite paper, wax tablets for bite marks to check the occlusion state, these methods can only check the state of rest after bite movement, due to the lack of time, this element can not be directly The dynamic contact between the start of slippage and slippage was observed. In addition, the bite paper, wax tablets into the mouth for examination, easy to cause changes in physiological bite position, but also affected by saliva, so in recent years began to use bite sound to check the occlusion state. Bite sound analysis is the upper and lower teeth of the impact or slip away from the vibration through the bone conduction or air conduction by the sensor
