Tooth mobility was measured mechano-electronically with the aid of quasi-static and dynamic methods in 309 patients comprising 2650 teeth being periodontally healthy. Besides, clinical and roentgenographic findings were ascertained to relate functional features to each periodontium. In general the result was that teeth loaded excessively show increased mobility parameters compared to those loaded normally. However, the mobility of teeth loaded poorly or deficiently was even greater compared to teeth stressed excessively. Moreover, follow-up studies showed that tooth mobility decreases after removal of functional disorders of the masticatory system or an immobilisation of splinted teeth. An experimental trauma of the periodontal ligament also brings on an increased tooth mobility which decreases to the original values some days after the trial.
借助准静态和动态方法，以机电方式对309例患者（共2650颗牙周健康牙齿）的牙齿松动度进行了测量。此外，还确定了临床和X线检查结果，以将功能特征与每个牙周组织相关联。总体结果是，与正常受力的牙齿相比，受力过大的牙齿显示出更高的松动度参数。然而，与受力过大的牙齿相比，受力不足或欠佳的牙齿松动度甚至更大。此外，随访研究表明，在消除咀嚼系统的功能障碍或固定夹板牙齿后，牙齿松动度会降低。牙周膜的实验性创伤也会导致牙齿松动度增加，在实验几天后会降至原始值。
