title: Double-casting method for fixed prosthodontics with functionally generated path.
abstract: BACKGROUND
  The construction of precise fixed prostheses that are harmonious within the stomatognathic function has been regarded as a critical requirement for successful oral rehabilitation. However, techniques for construction have been unsuccessful in producing a prosthesis that can be inserted without intraoral occlusal adjustment.
  
  
  OBJECTIVE
  In this study, a new method of constructing a precise prosthesis that requires limited occlusal adjustment at the final seating is described.
  
  
  METHODS
  The precision of this method was compared with a conventional method. Fourteen artificial crowns were fabricated on an experimental abutment by using both double-casting and conventional methods. The distances between the cusp tips and occlusal surfaces of the abutments, which were measured on wax/resin patterns and resultant crowns, were recorded to estimate clinical error for each method.
  
  
  RESULTS
  Error for the double-casting method was markedly less than the conventional method. This study demonstrated that a new double-casting method was precise and sufficiently reliable for clinical application.
