A crown is a dental restoration that covers a tooth in order to improve his strength and the appearance of tooth. A zirconium crown is a type of all-ceramic crown made from zirconia, a very strong material which is compatible with the human body. Because of its strength and durability, Zirconia is used in many other medical applications, for example artificial joints.

Zirconia is a type of crystal which is indestructible and lasts longer than other crowns. It is safe to use and preferred by many people to porcelain fused to metal crowns because there is no fear of our body rejecting Zirconia or displaying an allergic reaction to it. Unlike other type of crowns, these restorations won’t corrode so there is no blue gum around the tooth, no electrical conductivity and the tooth will look natural.

Advantages of a Zirconiam Crown

Milled, Not Cast — The CAD/CAM Advantage

A zirconium crown is not poured or cast like old metal work. We scan the prepared tooth, design the crown on screen, and a 5-axis machine mills it from a solid disc of medical-grade zirconia in our own Smile Infinity laboratory. Digital design plus in-house milling means a margin that fits to the micron, fast turnaround, and a result we control from start to finish — no outsourcing, no guesswork.

Monolithic or Layered — Strength and Beauty

Zirconia can be used two ways. A full-contour, monolithic crown is milled as one solid piece for maximum strength — ideal for back teeth and heavy bite forces. A layered crown carries hand-applied porcelain over a zirconia core for the deepest translucency — ideal for the smile zone. We choose tooth by tooth between raw power and refined aesthetics, and often combine both across an arch.

How We Bond Zirconium — Variolink by Ivoclar

Zirconia is dense and bonds differently from porcelain. We cement zirconium crowns with Variolink by Ivoclar, an adhesive resin cement engineered for high-strength ceramics, after conditioning the inner surface so the crown locks permanently to the tooth. Thin porcelain veneers, by contrast, are bonded with Ultra-Bond Plus by DenMat. The right cement for the right ceramic is not a detail — it is the difference between a restoration that lasts for years and one that loosens.

Zirconium vs. E.max — Choosing the Material

Both are metal-free and biocompatible. Zirconia is the strongest ceramic we use — the choice for crowns, bridges, molars and grinders. E.max lithium-disilicate is more translucent and is our preference for single front crowns and veneers, where light behaviour matters most. Many full-mouth cases use both: zirconia where the load is, E.max where the light is, and our ZEvolution German-technology system where a signature finish is the goal.

One Plan for the Perfect Smile

Crowns rarely stand alone in a makeover. We design the full result digitally and preview it with a smile mock-up first. If the gum line is uneven, laser gummy-smile correction reshapes it. If the lips need balance, our Smile Infinity plastic and dermatology department refines them. Crowns, veneers, gums and lips — designed together on our CAD/CAM and 3D-printing workflow in the Smile Infinity laboratory.

Every case is led by Dr. Habib Zarifeh — International Cosmetic Dentist and Dental Implants Surgeon, Head of Oral Surgery at CMC Hospital Beirut (affiliated with Johns Hopkins International), MSc in Laser Dentistry, RWTH Aachen, Germany, and founder of Smile Infinity Medical Centres across 12 countries.

It’s not a smile. It’s a signature.

Zirconium crowns has many advantages:

• Extraordinarily Tough.
• Can withstand hard grinding and biting.
• Translucent enough to be similar to natural teeth.
• Less tooth removal
• No Metal Fuse
• Modifiable size, shape and Color
But the main three advantages are:
1. Strength: It lasts longer than any type of crown.
2. Aesthetics: Because of its attractive translucent color, this crown blends in well with the other teeth.
3. Retain more of the existing tooth: More of the Original tooth is preserved. This is useful if the crown needs to be removed.

So a good choice if you are looking for a strong, long lasting and visually appealing crown. They are perfect at covering of damage or staining as well as helping to maintain the function of the tooth.
