Gold is one of the more ideal restorative materials, with better compatibility with human tissue, less irritation, and generally no gingival margin inflammation.

Disadvantages: processing is difficult, the bonding strength of pure titanium and porcelain is not as strong as porcelain and precious metal alloy and nickel-chromium alloy, and the edge fit is also worse than the first two, and the price is relatively expensive. ◆6 gold-platinum alloy porcelain teeth: gold content 85%, platinum content > 10%, stability, processability, strength, color are very good, gold-orange-yellow base color and human gum tissue tone close, no gray-black edge problems, looks beautiful and natural. This is a very ideal material for metal inner crowns, but the cost is higher. ◆7 Gold-deposited porcelain teeth: It fits very closely to the real teeth that have been worn small, and the inner crown is light yellow, making the overall shade of the porcelain crown more similar to the real teeth.
