Objective: Using finite element method analysis of two-tier structure decorated with porcelain occlusal thickness and the thickness of the core porcelain occlusal zirconia all-ceramic crowns internal stress distribution, and provide a theoretical basis for clinical production of all-ceramic crowns, thereby enhancing the use of prosthesislife expectancy.Methods:Maxillary first molar zirconia all-ceramic crowns dimensional finite element model, [...]
Objective:To study the condition and character of stress distribution in the mandible by use of 3D finite element analysis, of which forces are applied on chin.Methods:The electronic CT images of mandible were scaned and then imported to the Mimics software. A 3D finite-element model of mandible was finally established. At the angle of 90°,0°, and [...]
Root canal therapy (RCT) is currently the most effective treatment for pulp and periapical diseases. Root canal preparation, which includes cleaning and shaping of the root canal systems, is one of the key steps of RCT procedure. The aim of root canal instrumentation is to forming an ideal canal shape (continuous tapering), which is essential [...]

Objective: The study was designed to reduce the cost of production of dental bracket.We built four different bottom structure of dental brackets model in the method of three dimensional finite element analysis on computer frist. And analysed the variability of the stress distribution and the maximum deformation of each model, thus assess the quality of [...]

Objectives:To generate the three-dimensional finite element models with three different retainer designs and evaluate in vitro their influence on the strength of two-unit cantilever resin-bonded bridges(CRBB), using three-dimensional finite element analysis.Methods:The maxillary first premolar was scanned using Micro-CT technique. Three models with different retainer designs were constructed on M1 (the groove-shaped group), M2 (the D-shaped [...]
Objective Comparative Study the biomechanical behavior of three models of the femoral neck by application of three-dimensional finite element to explore some biomechanical basis of femoral head interior supporting system in treatment of femoral head necrosis.Methods 1.According to the different intervention, we establish laboratory model of femoral head into three groups : Normal model of [...]
Objective The purpose of this study is to establish three-dimensional finite element model of healty human knee including the posterior cruciate ligament (PCL) and lateral collateral ligament (LCL) with a set of consecutive MRI images and three-dimensional finite element software(ANSYS software). In this model,the PCL was removed to simulate its injury of gradeⅢ.Then we calculated [...]
