Temporomandibular joint vibration analysis (JVA) is the electronic recording of TMJ sounds, or, more accurately, vibrations occurring in the joint. Utilizing vibration transducers called accelerometers, a characteristic wave pattern is created for the various types of internal joint vibrations (conditions). Whereas the human ear cannot hear many of the frequencies that occur in the TMJ's, the accelerometers record all frequencies with equal efficiency. Once a vibration has been recorded, then it can be compared to other types of vibrations. This may make it possible to categorize the various types of internal conditions, and then, to monitor the joint status throughout treatment. Sample patients are shown with the initial and then progress joint vibration analyses. This electronic device may help answer the questions of whether orthodontic treatment helps, harms, or has any affect on the internal health of the TMJ. It may also be used to monitor different types of orthodontic treatment to help determine whether one type is more beneficial to the TMJ or not.
颞下颌关节振动分析（JVA）是对颞下颌关节声音的电子记录，或者更准确地说，是对关节中发生的振动的记录。利用称为加速度计的振动传感器，为各种类型的关节内部振动（情况）创建特征波形图。虽然人耳听不到颞下颌关节中出现的许多频率，但加速度计能以相同的效率记录所有频率。一旦记录到振动，就可以将其与其他类型的振动进行比较。这可能使对各种类型的内部情况进行分类成为可能，然后在整个治疗过程中监测关节状态。展示了样本患者的初始和进展期关节振动分析。这种电子设备可能有助于回答正畸治疗对颞下颌关节内部健康是有帮助、有害还是有任何影响的问题。它还可用于监测不同类型的正畸治疗，以帮助确定一种类型是否对颞下颌关节更有益。
