What are the various types of materials used for making dental crowns?
Dental crowns are made from all metal, porcelain-fused-to-metal, ceramic, resin etc. Details are given below. • Metallic dental crowns – the metals used are gold, palladium, nickel, chromium etc. The metal crown need less removal of tooth structure and causes less tooth wear to the opposing teeth. Metal crowns last longer and can resist wear-out due to chewing and biting. Chipping or breaking instances are very rare in metallic crowns. The main disadvantage in using metal crowns is their color; hence they become better choice for out-of-sight molars. • Porcelain-fused-to-metal dental crowns – this has the advantage over metallic crowns in color matching to your adjacent teeth. However, this wears out the opposite teeth more as compared to resin or metal crowns. It is also possible that the porcelain portion of the crown might break or chip off. The porcelain-fused-to-metal crowns when fixed adjacent to the all-ceramic crowns looks similar to normal teeth. The main disadvantage in this
