The choice depends on multiple factors, including the tooth’s location, the patient’s bite, esthetic expectations, and long-term durability needs.
To help your team guide patients toward the best restorative outcome, here’s an overview of the most commonly used crown materials and their unique benefits:
PFM crowns combine a durable metal substructure with a tooth-colored porcelain overlay, offering a balance of strength and esthetics. This traditional option has long been used for both anterior and posterior restorations due to its proven performance. The metal core provides excellent strength for load-bearing areas such as molars and premolars, while the porcelain exterior creates a natural-looking finish that blends with surrounding teeth.
PFMs also have a long clinical track record, making them a trusted choice across many case types. However, one drawback is that the metal underneath may become visible over time, especially if gum recession occurs, creating a gray line at the margin. Additionally, PFMs are typically less translucent than all-ceramic options, which can affect their appearance in the esthetic zone.
All-ceramic crowns are made entirely of porcelain or ceramic, with no metal components. They are favored for their lifelike appearance and are often the first choice for restoring front teeth. These crowns offer superior esthetics thanks to their ability to mimic the translucency of natural enamel. They’re also an excellent option for patients with metal sensitivities, as they are biocompatible and metal-free.
Available in various ceramic formulations, all-ceramic crowns can be tailored to achieve highly accurate shade matching. That said, they may not be the best option for molars or for patients who grind their teeth, as they are generally less resistant to high biting forces compared to other materials.
Zirconia crowns are crafted from a high-strength ceramic known for its exceptional durability and fracture resistance. This material is gaining popularity due to its ability to perform well in both posterior and esthetic applications. Monolithic zirconia offers impressive strength, making it ideal for patients with heavy bite pressure or bruxism. It’s also biocompatible and metal-free, providing a safe long-term option for patients with sensitivities. Zirconia crowns are available in both solid (monolithic) and layered versions, offering flexibility between durability and esthetics.
However, solid zirconia can be less translucent than natural teeth, and layered options require precise shading and polishing to achieve a natural look. Choosing the appropriate type of zirconia and working with a skilled lab is essential for optimal results.
E.max crowns are made from lithium disilicate glass-ceramic and are known for their ability to combine esthetics with moderate strength. These crowns are especially well-suited for anterior and premolar teeth where appearance matters most. E.max offers excellent translucency and shade-matching capabilities, making it a popular choice for cosmetic cases. It is also compatible with CAD/CAM workflows, allowing for efficient digital design and milling.
Compared to traditional porcelain, E.max provides added strength, but it may not be sufficient for molars under intense pressure or for patients with significant grinding habits. As with all restorative choices, case selection plays a key role in long-term success.
Full metal crowns are fabricated from materials such as gold alloys, palladium, or base metal alloys like nickel or chromium. These crowns offer unmatched strength and longevity, making them ideal for molars or other posterior teeth that endure significant chewing forces. Metal crowns are also gentle on opposing enamel due to their smooth surface, and they provide a highly stable fit — especially useful in cases with limited space.
Despite their functional benefits, metal crowns are not tooth-colored, which limits their use in visible areas. Additionally, noble metals like gold can significantly increase material costs, which is an important factor for some patients.
There’s no one-size-fits-all solution when it comes to crown materials. Each patient presents with unique clinical and esthetic needs, and the right choice depends on balancing durability, appearance, and function. By understanding the benefits and limitations of each material, your team can confidently guide patients toward the restoration that best supports long-term oral health.
