Multi-purpose gold alloys (Degunorm, Degudent LTG) were investigated as casting metal for conical double-crown telescopic prosthesis. Bond strength between porcelain and metal was compared to conventional ceramo-metal system. In addition, bond strength with some four treatments was also examined. The results were as follows:<BR>1. Bond strength of multi-purpose gold alloy with its original low-fused porcelain was similar to those of conventional dental porcelain-fused metal.<BR>2. Bond strength of Degunorm painted bonding agent after sandblasting showed the highest value under all test conditions in this study.<BR>3. According to SEM observation, body-opaque interface after firing was definite. However, bondingopaque interface was not distinguishable.<BR>4. The values of Vickers hardness (Hv) for body, opaque and bonding porcelain were 712, 325 and 468respectively.<BR>5. Particle size of opaque porcelain was approximately 50 pm, and was coarser than that of bonding porcelain.<BR>6. Leucite was detected in all of porcelain powders before firing. However, the leucite peak of body powder drawn in the X-ray diffraction chart was not obviously steep because it was amorphous.
