Numerical simulation of hydro-mechanical coupling of periodontal ligament.

Orthodontic tooth movement in the alveolar bone is due to the mechanical response of periodontal ligament to applied forces. Definition of a proper constitutive model of the periodontal ligament to investigate its response to orthodontic loading is required. For this purpose, a three-dimensional finite element model of incisor tooth, periodontal ligament, and bone was built utilizing the hydro-mechanical coupling theory.

Thermal Analysis of Dental Implants in Mandibular Premolar Region: 3D FEM Study.

Purpose: The distribution of temperature in a dental implant following hot food and beverage consumption is essential for evaluating the hazard this process may have on bone health. The purpose of this study was to predict the temperature distribution in the dental implant with/without a crown and the bone crest in contact with it using the finite element method.

Materials And Methods: A 3D model of the implant and the mandible was prepared by using computer-aided design software.
