Title: The Dentin Stress Analysis in the Restoration with Post-core-crown and Post-and-core Crown
Abstract:Objective To compare and analyze the stress change of the post-core-crown and the post-and-core crown,under the different dentin ferrule,the different load condition.Methods To construct the post-core...Objective To compare and analyze the stress change of the post-core-crown and the post-and-core crown,under the different dentin ferrule,the different load condition.Methods To construct the post-core-crown and the post-and-core crown model of the second mandibular bicuspid.And the finite element analysis software ANSYS was used to solve the variation of the dentin Von Mises stress.Results To the Von Mises stress peak value's size of the dentin,there was no obvious change between post-core-crown and the post-and-core crown;But to the Von Mises stress peak value's distribution of the dentin,the post-core-crown tended to root direction of a tooth.Conclusion When the post-core-crown restoration and the post-and-core restoration are carried in clinical,the base tooth root has the different tooth essence stress change.Read More
