What is the main indication for using a cast metal crown?

A cast metal crown is primarily indicated when high occlusal forces are anticipated due to its superior strength and durability compared to other materials. Cast metal crowns are fabricated by casting a high noble, noble, or base metal alloy that can withstand the significant forces generated during chewing and grinding. This makes them particularly suitable for posterior teeth, where the forces are highest.

Their robust construction allows them to maintain structural integrity and provide effective support for the tooth, especially in individuals with a strong bite or in those who brux. Other materials, such as porcelain, may be more aesthetically pleasing but lack the same level of strength, making them less ideal in situations where heavy occlusal forces are present.

While aesthetic concerns are important in dentistry, cast metal crowns are typically not chosen for their appearance. They are not the preferred choice when minimal tooth reduction is needed, as other restorative options can often preserve more tooth structure. Additionally, low occlusal forces do not necessitate the strength that cast metal crowns provide, making them less relevant in those scenarios.
