The 3D Finite Analysis Of Front Tooth Optimized Designed With Post-and-core Crown

After perfect root canal therapy to the residual root and crown of the front tooth,it is the main repair method to utilize a post and core crown at present.In order to get ideal dental prosthetic restoration,all kinds of posts are designed and already applied in the prosthetic field.At present,several kinds of post forms,such as cone post,parallel post,end with cone post,spiral post, etc. are applied to clinic.Different post has different impact on the influence of stress state of the root and dentin of the tooth.In addition,the post is fixed to the base tooth by the sticking pharmaceutical.As a result,the type and thickness of the sticking pharmaceutical will directly influence to the root and dentin of the tooth. So,the stability of post and the ability to antifold of the root have close relations with the post form and type,thickness of the sticking pharmaceutical.The stress distributed of the root and dentin of the tooth is influenced by many kinds of factors.Experimental study analysed about the single factor in the past.Our experiment was based on the optimization design mode of the three-dimensional finite element and regard transmitting and distributing as...
