title: Cast post and core foundation for the badly broken down molar tooth.
abstract: BACKGROUND
  This article addresses the difficult clinical problem of restoration of endodontically treated posterior teeth, where there is nothing left of the clinical crown.
  
  
  METHODS
  A step by step procedure, including instrumentation and materials and a new impression technique, is described in detail, with clinical photographs.
  
  
  RESULTS
  This technique results in the fabrication of a robust and extremely retentive post and core on which to place fixed prosthodontic restorations.
  
  
  CONCLUSIONS
  The author has placed over 600 restorations of this type over a five year period, without any reported failures. With the 'greying' of the population there are increased demands on dentists to restore structurally compromised teeth, and increasing expectations of the performance of these restorations. This technique is offered as a superior alternative to conventional post and core constructions methods.
