The Preferred Esthetic Restorative Material:
BruxZir® Zirconia or IPS e.max®?

BruxZir® Zirconia or IPS e.max®
For dentists who are bombarded with too many options for dental crown materials, there are two tooth-colored materials that offer consistent, reliable outcomes: BruxZir® Zirconia and IPS e.max®.

As with all clinical decisions, material selection is a matter of indication – each case is different. That’s why New West wants to make things easier by providing you with all the information you need to decide when to use zirconia and when to use IPS e.max.

BruxZir Zirconia

Zirconia crowns are well established as one of the strongest tooth-colored materials in dentistry. New West offers two types of zirconia crowns: BruxZir® Full-Strength Zirconia and BruxZir Esthetic Zirconia.
BruxZir Full-Strength and BruxZir Esthetic
BruxZir Full-Strength and BruxZir Esthetic are two types of monolithic zirconia that offer dentists a strong, reliable material for crowns, bridges, veneers and more.

As the name suggests, the main feature of BruxZir Full-Strength is its strength. This zirconia material demonstrates high survival rates against the toughest clinical forces.

  • > 1,000 MPa flexural strength
  • Uncompromising strength to withstand opposing forces in the posterior
  • 0.5 mm minimum reduction (1.0 mm ideal reduction)
  • Anterior and posterior bridges (up to 16 units)

BruxZir Esthetic is a durable zirconia material as well, but its main feature is its incredible esthetic appearance. For cases in the smile zone, BruxZir Esthetic is the ideal choice.

  • ≥ 870 MPa flexural strength
  • High translucency and lifelike vitality designed for the anterior
  • 0.7 mm minimum reduction (1.25 mm ideal reduction)
  • Anterior bridges (up to 6 units) and posterior bridges (up to 4 units)

Zirconia requires minimal preparation, making it easy for clinicians to prescribe it for a multitude of indications.

The versatility of these two monolithic zirconia materials allows clinicians to prescribe BruxZir for a wide variety of indications, including crowns, bridges, veneers, screw-retained crowns and full-arch implant prostheses.

IPS e.max

IPS e.max is made from a glass-ceramic material called lithium disilicate, which offers excellent esthetics and is considered the world’s best-selling glass-ceramic dental material.1

  • Affordable alternative to zirconia-based restorative materials
  • 500 MPa flexural strength
  • 1.0 mm minimum reduction (1.5 mm ideal reduction is recommended for the incisal or occlusal third)
  • Anterior bridges (up to 3 units)

IPS e.max
IPS e.max crowns offer high strength and durability.

Which is Preferred?

Deciding between BruxZir Zirconia and IPS e.max for a case primarily revolves around two central components: esthetics and function.
Both BruxZir Zirconia and IPS e.max have evolved with advanced manufacturing techniques over the years. Today, the materials are highly esthetic: Light transmission, reflection and color characteristics have been reevaluated to improve the lifelike appearance of these restorations. IPS e.max offers a more true-to-life coloration and translucency than zirconia restorations. The high esthetics of IPS e.max do come at the expense of the material’s flexural strength, which is substantially higher in zirconia restorations.
In terms of function, zirconia offers a more reliable strength and longevity. BruxZir Zirconia can also be used for a greater variety of indications. It requires less reduction on preparations and can be used for full-arch restorations. Functionally, zirconia is an ideal material for clinicians looking to prepare restorations that are likely to face the highest levels of toughness. BruxZir Esthetic serves as a suitable middle ground for dentists looking for the highest levels of esthetics with the highest levels of durability.

No matter what material you choose for your next restoration, BruxZir Zirconia and IPS e.max are excellent choices.
