摘要
介绍压电式加速度传感计测量物体固有频率的基本原理,并将其应用于口腔医学中,研制了牙用振动固有频率测试仪,对该仪器的结构、测试方法、特点做了简要介绍。本仪器可以广泛应用于口腔临床检查、诊断和研究。通过对天然牙、义齿、种植体固有频率的测定,可以进一步探讨其与松动度、结构强度、疲劳寿命之间的潜在关系。
The principle of measuring natural frequencies by accelerometers was described in the paper.With its application to stomatology,an instrument for measuring natural frequency of teeth was developed.Some information of the instrument was clearly explained,including its function,principle and advantages.The instrument can be used in the physical examination,diagnosis,research and so on.The natural frequencies measurement of teeth,dentures and implants by the instrument is the fundamental works for further research on the relationship between the natural frequency and the mobility,structure strength and fatigue life of teeth.
