“…Vibration is a natural property of the structure, and different structural style has different vibration characteristic [21]. The periodontal system can be regarded as an elastic buffer system that is made up of the tooth, the alveolar bone and the PDL connecting both of them.…”

The vibration characteristics of a maxillary central incisor were investigated by using the finite element method (FEM) according to nonlinear behavior of the human periodontal ligament (PDL). The effect of alveolar bone loss was also studied to obtain the relationship between the vibration property of the tooth in the periodontal system and the level of periodontal attachment for assessing the condition of periodontium. Three-dimensional (3D) finite element model of the tooth was constructed using CT image-reconstruction, and the elastic face foundation constraint was applied to the surface of the tooth root where the PDL was attached to. Modal analysis was performed by using FEM. The nonlinear behavior of the PDL was assigned and approached by the piecewise linearized method. The results indicated that the vibration of the maxillary central incisor in the periodontal system could be described by several modal frequencies and modes. The first four modes were dominant, which varied with the deformation of the PDL or the force applied on the tooth. The vibration frequency of the maxillary central incisor decreased with the losing of the alveolar bone, but the ratio of decrease had no significant correlation with the nonlinear behavior of the human PDL. The vibration frequency of the maxillary central incisor can be used to describe the loss of the alveolar bone and the level of periodontal attachment, under physiological short-term loading.

“…Many methods are used to evaluate the condition of the PDL [18,19], but most of them focus on the morphologic change of tissue or measurement in static state for example radiographic examination to assess the PDL condition. The support of a tooth is provided by the combined action of the PDL and the alveolar bone, and the PDL is a thin viscoelastic tissue made up of thousands of fibers to support the tooth [20,21].…”

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.

“…One‐way analysis of variance and the Tukey post hoc test were computed to test the variation of the damping ratio values. In addition, to obtain the resonance frequency and damping ratio values of alveolar bone, Laboratory tests were also performed on seven cadaver alveolar bones obtained from the Oral and Maxillofacial Physiology Laboratory, Taipei Medical University, Taipei, Taiwan as previously reported (Lin et al. 2006).…”
