A Simplified Technique for Retrofitting a Post and Core Foundation to a Pre-existing Crown: A Case Report

Esthetic and functionally restoration of endodontically treated tooth is commonly performed by a post and core. Many causes of failure can lead to fracture of abutment such as composite debonding, trauma and recurrent caries. This paper describes a simplified technique for fabrication of a casted post and core by retrofitting an old metal ceramic crown using duralay resin as model without the original die or its replica in a simple and time-saving way.
