Dynamic simulation of alveolar bone remodeling based on viscoelastic constitutive model of periodontal ligament

Dynamic simulation of alveolar bone remodeling is important for orthodontic study and clinical operation, but dynamic simulation based on tissue change has never been realized. Based on a remodeling model obtained from data in literature, using a viscoelastic constitutive model of periodontal ligament obtained by experiment data fitting, the alveolar remodeling progress was simulated with a program controlling the displacement of the external surface of periodontal ligament. Simulation with this method can describe tissue change in orthodontics and can be used to verify a supposed remodeling model, also can give guidance on the clinical operation.
