The shear bond strength of 12% Au-Ag-Pd alloy, when a flame spraying treatment was applied on the surface of it, working on 4-META/MMA-TBB opaque resin was compared with that of retention beads SSR. And the most suitable distance for each spraying powder was evaluated by compressive shear tests. The results of these tests indicated the following: 1. 442 sprayed at a distance directed by the maker had a significant strength by a higher average than retention beads SSR. 2. 442, 443 sprayed at a distance of 25 cm and 447, 43C sprayed at a distance of 20 cm showed the highest bond strength among those spraying distances (10cm, 15cm, 20cm, 25cm). 3. 442 sprayed at 20 cm and 25 cm had a significant bond strength by a higher average than retention beads SSR. 4. The shear bond strength at a distance of 10 cm had a tendency for every powder to lower. 5. A spraying distance of high shear bond strength was indicated between 20cm and 25cm at all spraying powders.
