Anterior Emax Crown

Q&A ABOUT EMAX CROWN AND ZIRCONIA CROWN

Zirconia & Emax are two dental materials that used broadly in manufacturing dental restorations recently. There are many questions relating to the advantages and disadvantages of Emax crown and Zirconia crown: Which one is better? Which one saving costs more? Which one is more durable and so on. Today, we will conduct a Q&A about the Emax crown and Zirconia crown to answer these questions.

Q:  WHAT ARE THE DIFFERENCES BETWEEN EMAX AND ZIRCONIA?

         Emax                 Zirconia
Chemical composition Lithium Disilicate All- ceramic material Zirconium Dioxide A white, powdered metal oxide, ceramic
Strength 380-500 megapascals Incredibly strong :800-1200 megapascals
Thickness Minimum thickness: 1.5-2mmm for strength Can be strong at the thickness of 0.5mm
Appearance Natural translucent Realistic looking Has a denser, opaquer look
The differences between Emax and Zirconia

Q: WHAT IS THE SUITABLE CHOICE FOR ANTERIOR AND POSTERIOR CROWNS?

 A: Zirconia is usually chosen for the posterior teeth, and Emax is chosen for the anterior teeth. This is because the posterior teeth often require a lot of force and are hidden inside, so they do not require aesthetics while the front teeth use less force and need more aesthetics. However, the final choice depends on the patient’s dental condition. Recently, the aesthetic of the Zirconia crown has been greatly improved, can be completely suitable for anterior and posterior dental restorations with outstanding durability and improved aesthetics.

Q: WHAT IS THE BEST CROWN FOR STRENGTH AND AESTHETICS?

A: Layered Zirconia restorations combine both the highest aesthetics and the strength and flexibility for all posterior and anterior cases. With layered Zirconia, there is no metal to show through the ceramic and unsightly black lines at the gingival margin. This aesthetic restoration is built on a coping composed of zirconium oxide, one of the strongest and most biocompatible ceramic materials. After being milled using CAD/CAM technology, the final restoration achieves intimacy of fit and a beautiful, translucent appearance.

Q: THE ADVANTAGES OF EMAX CROWN ?

A: Strength: The crowns have a monolithic structure, the strength of lithium disilicate is 380-500 MPa. Functionality: They completely restore the functions of the teeth in the chewing zones and are especially prominent for the anterior teeth areas. Aesthetics: Visually indistinguishable from natural teeth and do not have an opaque frame. You can choose the most accurate shade and transparency for the dentition of a particular patient. The color does not change under the influence of dyes. Comfort: Crowns are made on high-precision equipment, have an anatomical shape, provide a correct bite, excellent closing, comfort when chewing. Safety: Absolutely biocompatible, do not oxidize, do not cause allergies, irritation, so they are suitable for all patients. Durability: With proper care, the crowns serve for more than 15 years, preserving the original properties and appearance. This is one of the best indicators among dentures.

Q: THE ADVANTAGES OF ZIRCONIA CROWN ?

A: Strength: The crowns have a monolithic structure, the strength of Zirconium Dioxide is 800-1200 MPa. Functionality: They completely restore the functions of the teeth in all zones. Aesthetics: For the best aesthetic and strength, Layered Zirconia restorations will be the potential candidate. Comfort: Crowns are made on high-precision equipment, have an anatomical shape, provide a correct bite, excellent closing, comfort when chewing. Safety: Absolutely biocompatible, do not oxidize, do not cause allergies, irritation, so they are suitable for all patients. Durability: With proper care, the crowns serve for more than 15 years, preserving the original properties and appearance. This is also one of the best indicators among dentures.

Q: WHAT ARE THE DRAWBACKS OF THE ZIRCONIA CROWN?

A: The drawbacks of zirconia crowns are minimal. The strength of the material has raised some concerns about friction against the tooth root and wearing down opposing teeth. Frequent checks, however, help to reduce any possible risks to opposing teeth.

Q: WHAT ARE THE DRAWBACKS OF THE EMAX CROWN?

A: The known drawback is the price of the crown. Due to the best aesthetic, the E-max crown is much more expensive than other crowns.

 Q: HOW LONG TO MANUFACTURE EMAX CROWN AND ZIRCONIA CROWN?

A: At Xdent, we receive scanned files from customers. After finishing the design, all crowns will be milled with CAD/CAM technology to achieve the intimacy of fit and beauty. After that, our skilled technician will process more steps to get the final translucent appearance. All steps are finished in 2 days maximum.
