Restorative crown materials
Dental Crown Materials
Dental crowns are available in several material types including all-ceramic (zirconia, E.max), porcelain-fused-to-metal (PFM), and full-metal — each with different strength, appearance, and longevity profiles suited to different tooth locations and priorities.
Common uses
- Capping a damaged or heavily restored natural tooth
- The visible restoration placed on top of a dental implant
- Anchoring a dental bridge
Advantages
- + All-ceramic options provide the most natural appearance with no metal content
- + Zirconia crowns combine good appearance with high strength for most locations
- + Full-metal crowns offer maximum durability for back teeth when appearance is not a priority
Limitations
- − Porcelain-fused-to-metal crowns can show a gray line at the gumline as gums recede over time
- − All-ceramic materials have varying strength ceilings by material type
- − All crowns are restorations with an expected lifespan, typically 10–15 years, not permanent
Frequently asked questions
What crown material is used on top of a zirconia implant?+
Most commonly a zirconia or E.max ceramic crown — the crown material and implant post material are separate decisions, though some providers use a monolithic zirconia design that integrates both.
Is a porcelain-fused-to-metal crown a metal-free option?+
No — PFM crowns have a metal substructure with a porcelain coating. Patients seeking a fully metal-free crown should ask specifically for an all-ceramic option.
