In modern dentistry, the demand for aesthetically pleasing and functional restorations has led to the rise of advanced materials like zirconia crowns. Dental crowns, which are used to protect and restore damaged teeth, now come in various materials that balance strength, durability, and aesthetics. Zirconia crowns, in particular, have become favored for their remarkable ability to mimic the appearance of natural teeth while offering superior strength.
What Are Dental Crowns and Why Do They Matter?
A dental crown is essentially a cap that covers a damaged, decayed, or weakened tooth to restore its shape, strength, and appearance. Crowns play a crucial role in protecting and reinforcing teeth, especially after procedures like root canal therapy or when covering dental implants. The choice of crown material can have a significant impact on the tooth’s aesthetics, durability, and functionality.
Exploring the World of Dental Crowns.
- Emax Crowns:
Emax crowns are crafted from lithium disilicate, a high-strength glass-ceramic material known for its exceptional aesthetic appeal and durability.
Their natural translucency allows them to mimic the look of real teeth, making them an ideal choice for anterior restorations. Emax crowns offer a high level of strength as well, making them suitable for both front and back teeth. They are resistant to wear, provide excellent bonding to tooth structure, and come in a variety of shades for seamless blending with surrounding teeth.
- Zirconia Crowns:
Zirconia crowns are made from zirconium dioxide, a material prized for its incredible strength and biocompatibility.
Zirconia is highly resistant to chipping or breaking, making it ideal for patients who grind their teeth or require crowns on molars. Unlike metal-based crowns, zirconia is non-reactive and integrates well with natural tissues. Additionally, it is available in a variety of shades, offering a natural-looking solution with long-lasting durability.
- Milling v/s Layering of crowns
Both Emax and zirconia crowns can be produced as solid (milled) versions, which offer maximum strength and are typically used for posterior teeth, or layered versions that enhance translucency and aesthetics for front teeth. Solid crowns are more opaque and durable, while layered crowns offer a more natural, tooth-like appearance, combining strength and beauty for optimal performance in different dental zones. While Emax crowns are preferred for their translucency in front teeth, zirconia crowns stand out for their incredible strength, making them a better option for molars or patients prone to teeth grinding.
Your dental professional can help determine whether a solid or layered crown is the right option for your specific case, taking into account factors like tooth location and aesthetic preference. Other considerations include tooth wear, aesthetic goals, and cost when deciding between milled or layered crowns.

- Porcelain-Fused-to-Metal (PFM) Crowns:
PFM crowns feature a metal substructure that provides strength, topped with a layer of porcelain for a natural tooth-like appearance. These crowns are durable and long-lasting, though the metal core can sometimes become visible near the gum line over time, especially with gum recession.
This type of crown is still a popular option for both front and back teeth due to its strength and affordability, though less aesthetic compared to full-ceramic crowns.
- Ceramic-Facing on Metal Crowns:
Similar to PFM, ceramic-facing metal crowns have a metal base with a ceramic overlay. The metal provides strength, while the ceramic adds a more natural look to the visible portion of the tooth. However, the strength of the metal can compromise the aesthetic quality, as it lacks the translucency of full-ceramic options.
- Stainless Steel Crowns:
Mostly used for paediatric patients or temporary restorations, stainless steel crowns are known for their durability and affordability. They are commonly used on primary teeth and are easy to place but lack aesthetic appeal due to their metallic colour.
Conclusion: Tailored Solutions for Every Smile
In summary, dental crowns play a critical role in restoring and enhancing the appearance and function of teeth. From Emax to porcelain-fused-to-metal, each material brings its own strengths, catering to different needs.
PFM and ceramic-facing crowns provide durability, while stainless steel crowns are mainly used for temporary or paediatric treatments. Solid and layered versions of Emax and zirconia crowns offer versatility in strength and aesthetics.
Emax crowns are ideal for front teeth and veneers, thanks to their natural translucency, while zirconia crowns stand out for their strength, making them perfect for molars and patients prone to teeth grinding. Ultimately, the choice between Emax, zirconia, or other types of crowns depends on the location of the tooth, the patient’s bite, and their aesthetic preferences. visit Dental clinic In Bannerghatta to Consult your dental professional to choose the best crown for your smile!
