Abstract: The bond durability of composite-type resin cement was evaluated by means of cyclic impact tests using three different loads. In terms of experimental setup, a casting alloy, 12% Au-Pd-Ag, was used as the adherend and bonded to a cast block using a composite-type cement (Bistite II). A shear load--using plungers of three different weights at 100, 110, and 120 g--was dropped from a 3-mm height onto a small piece of the casting alloy until debonding. The cycle numbers that caused debonding were 1756 +/- 680 x 10(4) times for 100 g, 1403 +/- 515 x 10(4) times for 110 g, and 420 +/- 200 x 10(4) times for 120 g, respectively. Therefore, the group loaded with 120 g showed a significantly lower value as compared to the other two groups. On the fracture mode of the cement, it was a bulk fracture regardless of the loading weight employed in this study--the same result obtained in a previous study where heavier weights were employed.
