Three-Dimensional Finite Element Analysis Of Stress Distribution Of Reattached Maxillary Anterior Tooth

OBJECTIVETo establish the three-dimensional model of reattached maxillary central incisor,and analyze the distribution of stress.METHODSFound the model of reattached maxillary anterior tooth，imitate the stress andanalyze the distribution.RESULTSThe3D model of reattached maxillary anterior tooth was founded,3543nodesand dots were produced.Acquired the Von Mises stress and the distributioncloud atlas.CONCLUSIONSIncisor end is the stress centralization area when biting, the maximum stressequals159MPa.Stress distribution of the surface of fiber post isneglegible,differs from the conclusions that stress distributed on the surfacebetween post and dentin.Stress on amelocemental junction is obviouslydisplayed in cloud atlas.This result is the same as lots of researches.
