摘要
本文是出了一种客观确定牙松动的新方法。用瞬态碰撞激震测定牙固有振动半周期Ｔ／２和减幅系数η。以Ｔ／２为主，η为辅，度量牙齿的松动度。对依据的原理从牙周动力学模型出发进行了严密的数学推导；讨论了测试方案；介绍了牙模型测试实验；最后给出实际状态下测试的初步结果。
A new method of defining tooth mobility objectively was reported. Measurements of tooth natural vibration half cycle T/2 and ratio of amplitude attenuation η was done according to tooth vibration excited by instantaneous impact. We measured tooth mobility using T/2 as main andη as assist factor. Strict mathematical deduction was made using principles obtained from periodontal dynamic model Measuring program was discussed and experimental test of tooth model introduced. Besides preliminary results of actual measurement of tooth were given.
