How does GOLDTECH BIO 2000 develop warm porcelain shades?
A. Because GOLDTECH BIO 2000 is 99.7% gold it retains the true rich color of pure gold, which is the best background for developing warm porcelain shades. Alloy additions such as platinum, palladium or silver would whiten the yellow color rapidly. The rich yellow color of GOLDTECH BIO 2000 absorbs all of the shorter light wavelengths including the blue portion of the spectrum. The blue light is responsible for the dark line seen on traditional porcelain to metal restorations. The reflected light from GOLDTECH BIO 2000 does not contain any blue light so a dark shadow at the gingival is not seen.
