“…The alveolar bone was considered immovable, the restrictions of displacement were applied on the exterior surface of the PDL in three-directions [14,15]. To validate the model, the modal analysis of the maxillary molar in the periodontal system was performed at first using MSC software MARC-FEA.…”

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.

“…This step is crucial regarding the PDL's decisive influence of load transfer and stress/strain distribution in the tooth, the PDL itself and the surrounding bone. 5,15 The cementum layer was not modeled because of its small thickness and physical properties that are similar to those of dentin. …”

“…5,15,16 The conditions of analysis to simulate this model were considered when it behaved in a homogeneous and isotropic manner, i.e., all material properties were identical in all directions, and with a linear elastic behavior, in which deformation of the structure occurs linearly. After establishment of the analysis conditions, two situations of traumatic impact were simulated: a) a loading force of 500 N applied at a 45° angle, acting on the buccal surface of the crown in its central region (F1) and b) a loading force of 2000 N, acting in the same angle, surface, and region of the tooth (F2) ( Figure 2).…”

“…These effects can be direct when the consequences of trauma occur in the area of impact, such as tooth fractures, or indirect when the stress produced by the impact propagates to adjacent tissues and causes damage to these regions, such as root resorption resulting from periodontal ligament (PDL) necrosis. 4,5 Several methods have been developed in an attempt to better understand the stress distribution inside the dentoalveolar joint (DAJ). Such methodologies include photoelastic models, analytical mathematical models, and mathematical analyses, such as the finite element method (FEM).…”

Aim: The present study aimed to analyze the stress distribution in the dentoalveolar structures of a maxillary central incisor submitted to two situations of impact loading. Materials and Methods: The following loading forces were applied using a three-dimensional finite element model: a force of 500 N at an angle of 45° on the buccal surface of the crown and a 2000 N force acting in the same direction and surface of the tooth. Results: Harmful stress was observed in the second situation, suggesting damage to both the tooth and adjacent tissue. However, the damage found in soft tissues such as dental pulp, was negligible. Conclusion: Injuries resulting from the traumatic situations were more damaging to the integrity of the tooth and its associated hard-tissue structures. Uniterms: Tooth injuries.

“…Additionally, adding frictional boundaries conditions between teeth and active ligations for orthodontic appliances will continue to increase the accuracy of these models. Three dimensional dynamic simulations for assessing tooth injury, similar to those demonstrated in 2D studies (Huang et al, 2006;Miura and Maeda, 2008), should be reevaluated. While techniques will continually be optimized to improve numerical approximations, this does not negate the value of finite element techniques in dentistry.…”
