Digital versus conventional techniques for pattern fabrication of implant-supported frameworks.

Objective: The aim of this experimental study was to compare retention of frameworks cast from wax patterns fabricated by three different methods.

Materials And Methods: Thirty-six implant analogs connected to one-piece abutments were divided randomly into three groups according to the wax pattern fabrication method ( = 12). Computer-aided design/computer-aided manufacturing (CAD/CAM) milling machine, three-dimensional printer, and conventional technique were used for fabrication of waxing patterns.
