Abstract
It was proposed that the human tooth mobility should be analysed elastically on eight new conditions, and the tooth mobility of the human mandibular first premolars were analysed elastically on five conditions which really contain the experimental values of load-displacement on the human tooth. The upper and lower bounds are decided according to the distribution of the elastically analysed values on the above five conditions, and the upper and lower bounds of the values on the five conditions are assumed as the requisite conditions of the human tooth being dynamically equivalent to the simulate tooth models. Attempts were made to make a three dimensional simulate tooth which is dynamically equivalent to the human tooth, but four times large as the human tooth. It was proved that the model D-NO. 2 satisfied the above above conditions of the human tooth.
