An alternative post-and-core method for patients with limited interarch space

ABSTRACTBackgroundThe authors describe a technique for placement of a three-unit posterior fixed partial denture where one abutment lacked sufficient interarch space.Case DescriptionThis method involves the use of a cast post and core with a precision attachment soldered into the core to provide the necessary retention and resistance. The prosthesis is retained by a combination of cement and screw retention.Clinical ImplicationsThis method is desirable when there is insufficient interarch space for a conventional post-and-core restoration. Achieving internal reinforcement by connecting the precision attachment to the residual root should provide the prosthesis with retention and added stability.
