The advanced Capillary Attraction Technology of Captek combined all the advantages of high-purity gold with a platinum / palladium alloy producing exceptionally strong copings. Because this is not a cast coping, there are no dark oxides on the surface to discolor the porcelain. This provides the perfect platform for the ceramist to build upon…creating restorations that are warmer, more life-like and blend better with natural teeth. No more harsh black lines associated with traditional porcelain fused to base metals crowns. Captek has been clinically proven to reduce the accumulation of harmful bacteria and plaque up to 90 percent better than the natural tooth structure! No special preparation or bonding techniques are required with Captek, saving valuable chair time during preparation and replacement.
