MBF-Ⅰ型力仪的研制和应用

A Study of MBF-I Type Gnathodynamometer and Clinical Application in Dentistry

本(牙合)力仪采用电阻应变技术原理研制而成。该仪器灵敏度高、功能齐全,可打印、显示、储存统计资料,还可绘制(牙合)力曲线图、动态反映(牙合)力变化。用该(牙合)力仪测试309例正常牙7597颗的(牙合)力。

The MBF-I type gnathodynamometer was adopted from resistance strain-gage mea-suring techniques.The key in this study was designed by using a transducer and com-puter.This device has multiple functions.The range of the biting force being testedwas from 0 to 100 kgf,accuracy was 0.5%.Temperature range was from -20℃ to 50℃The values of the biting force obtained can be expressed by drawing a curve,which mayreflect the dynamic changes of the biting force.This device also can autocalculate themaximum biting force,storing and recording the sex,age and biting force values of thepersons be tested,The MBF-I type gnathodynamometer has been used for measuring.7597 teeth of 309 persons in four hospitals.
