Permanent crowns can be made from all metal, porcelain-fused-to-metal, all resin, or all ceramic. · Metals used in crowns include gold alloy, other alloys (for example, palladium) or a base-metal alloy (for example, nickel or chromium). Compared with other crown types, less tooth structure needs to be removed with metal crowns. Tooth wear to the opposing teeth is kept to a minimum. Metal crowns withstand biting and chewing forces well. They last the longest in terms of wear down and they rarely chip or break. The main drawback is the metallic color. Metal crowns are a good choice for out-of-sight molars. · Porcelain-fused-to-metal dental crowns can be color matched to your adjacent teeth (unlike the metallic crowns). However, more wearing to the opposing teeth occurs with this crown type compared with metal or resin crowns. The crown’s porcelain portion can also chip or break off. Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth. However, sometime
