The Great Quality of an Istar Emax Crown

Emax dental crowns are made from an advanced lithium disilicate glass-ceramic, a material that has changed how we do dental repairs. This groundbreaking material is a key part of modern dental work, offering a one-of-a-kind mix of strength, long life, and a natural look.

Amazing Material: The Science and Strength Behind It

The great performance of Emax dental crowns comes from the careful design of the way it’s made and its internal structure. This advanced ceramic is mainly made of lithium disilicate (Li2Si2O5) crystals, carefully placed inside a silica-based glassy material.

The main innovation behind lithium disilicate is its special crystal-forming process. This process creates a unique internal structure that has interlocking, needle-like crystals inside a glassy material. This complex structure gives a great balance of high flexural strength, usually between 360 to 400 MPa, and an excellent see-through quality. This mix allows for the creation of very natural-looking repairs that look a lot like real teeth, solving the old problem of choosing between strength and looks.

Key Physical Properties:

• Flexural Strength: The flexural strength of lithium disilicate is usually measured in the range of 360–500 MPa. Pressed ceramic versions often have numbers at the higher end (400–500 MPa), while CAD/CAM-milled blocks are typically in the 360–400 MPa range.
• Fracture Toughness: The fracture toughness (K_IC) of lithium disilicate is generally between 2.5–3.3 MPa·m^0.5. This is much higher than standard feldspathic porcelains (around 1 MPa·m^0.5), a key reason it works well in the clinic.
• Translucency and Optical Properties: Lithium disilicate has a great see-through quality. This feature allows it to look a lot like natural tooth enamel. The mix of its glassy material and controlled crystal size allows us to make different levels of translucency (e.g., High Translucency, Low Translucency), which can be custom-made to match different appearance needs.
• Bonding and Adhesion: Having a glassy material allows for effective etching with hydrofluoric acid and then silanization. These are key steps to get strong resin-ceramic bonds (usually >25 MPa shear bond strength). This is a big advantage over other ceramics like Zirconia.

Healthy and Safe

• Biocompatibility: Many lab and clinical studies have always shown the high biocompatibility of lithium disilicate. It is not harmful to cells and is very gentle on gums, making it very safe to use in the mouth for a long time.

The Istar Lab Advantage: Following Best Practices

When you partner with us, you get more than just a product. You get a team. Our expert dental technician staff uses the best technology and clinical knowledge.

How They’re Used: From a Single Tooth to a Full Smile Makeover

Today, lithium disilicate is seen as a top choice for single-unit crowns, veneers, inlays, and onlays, especially in the front of the mouth.

• Anterior Teeth Restoration: An Emax crown is perfect for a front tooth. It works well for any tooth in the “Aesthetic Zone,” like an incisor or canine.
• Posterior Teeth: While Zirconia is often used for back teeth, a strong Emax crown is also a great choice for a molar or premolar, especially when looks are important.
• Damaged Tooth Repair: It is the best solution for a cracked tooth or after a root canal procedure.
• Full Mouth Reconstruction: For bigger cases, we can make a full set of Emax dental crowns to create a stunning smile makeover. This is where our digital smile design service shines.
• Dental Implant Crown: An Emax crown is a beautiful choice to place on a dental implant to replace a single tooth.

Unmatched Results, Long Life, and Great Looks

The performance of Emax dental crowns is known for lasting a long time, being very strong and hard to break, and looking great. This makes them a top choice for dentists and patients who want the best.

Long-Term Survival and Strength:

Early clinical tests showed they last a long time, always over 95% after five years for lithium disilicate crowns and veneers. These early studies proved the material gives dependable results in both front and back teeth.

Many long-term studies show 10-year survival rates for Emax crowns between 91% and 97%. These rates are as good as, and sometimes even better than, traditional PFM crowns.

Lab tests show that Emax crowns are very hard to break. The average breaking force is typically between 1200–2200 N. These numbers are much stronger than normal chewing forces, showing they are very strong.

Looking Great: The Gold Standard

Lithium disilicate glass-ceramic is specially designed for its great light-handling abilities, making it the best choice for natural-looking repairs.

• Lifelike Translucency: The special internal structure allows for the best way for light to pass through and spread out. It acts just like natural enamel and dentin, creating a great see-through and glowing look.
• Natural Light Dynamics: Lithium disilicate has a very natural glow, with measurements that are very close to natural enamel. This feature allows the crowns to show a special bluish-white look in reflected light and a warm orange-brown color in light that passes through, perfectly copying the way light plays on real teeth.
• Precise Color Matching: Emax crowns are available in a wide range of pre-shaded blocks and can be additionally personalized with stains and glazes. They can match colors so well you can’t see the difference, which means they are a great color match for the teeth next to them.
• High Patient Satisfaction: Clinical studies consistently show high patient satisfaction rates (over 90%) with Emax crowns, especially for their natural color, see-through quality, and overall look.

Comparing Your Repair Options

We know you have many choices. The conversation often comes down to Emax vs Zirconia crowns. Looking at all Emax crown alternatives is important. Here is a simple table to help you decide.

Beyond a standard crown, we also make Emax onlays and inlays. These options save more of the tooth than a full crown. When we discuss veneers vs crowns, we can help you choose the best option based on the clinical need. For some cases, a Maryland bridge might even be a solution.
