The purpose of this study is to investigate the effect on the bending test conditions of the composite resin blocks for CAD/CAM. Three point bending tests with the fulcrum distance of 5 mm, 10mm, 15mm and 20mm were performed, concurrently a biaxial bending test was also performed. In general, it was found that the bending strength increased with the decrease of fulcrum distance. Therefore, the shortest fulcrum distance of bending test provides the apparently largest bending strength.
