Gold has long been a preferred choice for clinicians because of its longevity and functional success. With precious, semi-precious, and non-precision metal options, Gold remains a proven material choice for a broad spectrum of clinical needs.
Full Gold Crowns (FGCs) consist entirely of a single piece of alloy. Although commonly cited as a "Gold" crown, this catagory of crown is actually composed of many different types of metal elements, including but not limited to: Gold, Platinum, Palladium, Silver, Copper and Tin. The first four elements listed are noble metals, while the last two listed are base metals. Full Gold Crowns are of better quality when they are high in noble make-up. According to the American Dental Association, Full Gold Crown alloys can only be labeled as high noble when they contain at least 60% noble metal, of which at least 40% must be Gold.
In addition to being non-corrosive and hypo-allergenic, Gold is the most non-toxic and biocompatible metal used in dentistry, Gold margins do not break or chip, even with polish and wear. Gold's wear rates and coefficient of thermal expansion is very similar to enamel, and thus accomplishes a better natural fit. Often times less tooth structure is removed when preparing teeth for Gold, which leaves the tooth stronger and healthier overall.
