摘　　要：首先简要介绍目前测量牙齿松动位移的主要方法,并分析了各自的特点和造成误差的主要原因。着重阐述了采用双激 光位移传感器检测牙齿相对位移装置的检测原理、设计方案以及相关性能指标。采用附带压力传感器的探杆配合操作,可为 有关牙动度的医学研究和临床提供较精确的变力下牙齿松动位移测量数据。The methods of measuring tooth mobility displacement are reviewed and their characteristics and the errors occurred are analysed. The principle, design scheme and performance of the instrument, which are based on double laser sensor, are described. Choosing the way in which the handgrip works with pressure sensor can help those who working for measuring tooth mobility displacement or working in clinic to get more accurate data.
