[Studies on the mechano-electronic measurement of tooth mobility].

The correlations between dynamic and quasi-static mechano-electronic measurements of tooth mobility were investigated in more than 1500 teeth. The two methods correlate quite well with the conventional classification (in Germany). On the other hand, there is no correlation between dynamic and quasistatic mechano-electronic measurements. Nevertheless distinctive signs and periodontal findings could be verified by mechano-electronic evaluation of tooth mobility.
