Abstract

The dynamic response of a maxillary molar with periodontal ligament (PDL) was investigated to explore the dynamic behavior of the tooth. Three-dimensional (3D) finite element model of a maxillary molar with periodontium was constructed using CT image-reconstruction. The modal vibration of the maxillary molar in the periodontal system was performed at first, and then the dynamic response of the tooth under an impact loading was calculated and compared with the results of the different periodontal attachments in order to assess the condition of the periodontium. The first four modes were dominant in the modal vibration. The resonant frequency of the maxillary molar under the impact loading was close to the frequency of the second mode in the modal analysis. The resonant frequency decreased gradually with the loss of alveolar bone, while the resonant amplitude increased nonlinearly. The resonant frequency and amplitude of the maxillary molar can be used to describe the loss of alveolar bone and the condition of periodontium.
