To reduce the radiation dose in dental computed tomography (CT), backprojection-filtration (BPF) algorithm is the preferred choice as it can reconstruct images from truncated data within limited scanning angle, thereby reducing radiation dose and avoiding irradiation to the brain. However, the integral interval of backprojection is variable for every PI-line which causes the calculation efficiency...
How to build a precise finite element model for periodontal ligament (PDL) of impacted tooth is a key step in numerical simulation of orthodontics. However, it is difficult to obtain accurate three-dimensional model of impacted tooth which embed in alveolar bone. In this paper, combined with reverse engineering and CT image, a new finite element method is introduced. Firstly, create the surface model...
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...
