A step ahead in post and core technique for patients with limited interarch space

The successful treatment of a badly broken down tooth with pulpal disease depends not only on a good endodontic therapy but also on a good prosthodontic reconstruction of the tooth following the root canal treatment. Often, we come across an endodontically treated tooth with little or no clinical crown. In such cases, a postspace is prepared into the canal for the cementation of post and an artificial crown structure called the core is prepared over it to support the fixed partial denture. Post and cores though commonly used now have their own limitations. Failures associated with these systems include the loss of retention of posts and fracture of roots or even root perforations. Moreover, placement of a post in situations with limited interarch space is a challenge for any dentist. The failure rate associated with the conventional techniques would be higher in these conditions. This case report discusses an alternative technique of restoration of a badly broken down endodontically treated tooth with a specially designed post and core attachment to provide the necessary resistance and retention form for the overlying prosthesis in patients with limited interarch space.
