Abstract:
Objective:To improve stress analysis in stress-intensive regions of human periodontal tissue. Methods:Based on coarse analysis on the finite element(FE) model including human teeth and periodontal tissue, the submodel method was introduced to analyze the stresses in interested region such as apical. Results:Submodel analysis showed same stress distribution as FE model while more precision of stress value was obtained by submodel because refined mesh was used.Conclusion:More accurate stresses measurements in local regions can be obtained by submodel method.
