Abstract:

Post-core-crown is a widely used restorative m ethod in clinic. Despite there are series of theoretical and experim ental studies about the physical and mechanical ability of post-core-crown, there also remains disputes in the retention and resistance of dentin ferrule, the relation between the elastic modulus of post-core and stress distribution, whether the use of post can strengthen the resistance strength of teeth. This review makes a summarization with these and put forward some questions that need advancing in research.

Key words: post-core-crown, dentin collar, post, elastic m odulus
