Abstract

In this paper, the assessment and comparison of the biomechanical reactions that occur in the fluid periodontal ligament during tooth movement have been emphasized. Using the finite element method we developed three-dimensional models of the central maxillary incisor and we simulated case studies with forces of progressively ascending intensities. We identified the stress distribution depending on the direction of the orthodontic force and the distribution of displacements, both by quantitative and qualitative methods. As the force and the degree of bone resorption increased, displacements and stress in the direction of force progressively increased, as parameters of orthodontic biomechanics..
