[Results of measuring tooth mobility by a two-parameter periodontometer]

A new method for evaluating mobility of a tooth and area of its periodontium is suggested. The evaluation of elastic and viscous components of tooth mobility is based on theoretical estimations. Clinical evaluations of tooth mobility were carried out in patients with physiologically normal periodontium making use of a two-parametrical periodontometer. Experiments demonstrated that the ratio of elastic to viscous components of the tooth mobility is proportionate to periodontal area. Two-parameter periodontometer gives data on complete mobility of a tooth and periodontal area.
