Zirconia That Delivers Esthetics and Maxes Your Profit In the Practice

The New Zirconia Workflow

Cementing and bonding zirconia is a crucial factor in restoration survival and patient peace of mind. Clinicians need to balance ease in preparation, patient-approved esthetics, and predictable longevity through an approach that supports practice efficiency and income. Unfortunately, there is often conflicting information on how to handle advanced materials and techniques most effectively.

In considering your specific zirconia choice, take advantage of your Burbank Dental Lab technical advisor as a resource. They have specific knowledge of material properties, and access to digital technology.

Zir-MAX.M e® in Your Practice

1. Simplicity of Cementation

Zir-MAX.M e® can be placed with either conventional cements or bonded, making it fit into whatever procedures work best for you in your clinical judgment. When bonding, use adhesive systems with dual cure resins. When cementing use a low expansion cement, like resin-modified glass ionomers.

2. Preparation

It is not necessary to use a shoulder preparation. Feather-edge preparations are acceptable. Ideal minimum margin preparation is 0.3 mm chamfer, but all margin preparations may be used, including a full shoulder.

• 1 mm axial wall reduction
• 1 mm cingulum / occlusal reduction required.
• Note: As with any all-ceramic, no sharp or right angles.

Adjustment Tips

• When adjustments are necessary for fit, adjust prepped tooth.
• When occlusal adjustments are required on the monolithic zirconia material, use a diamond with water. Most all rotary instrument companies carry specific diamonds that they recommend for adjusting zirconia.
• It is crucial to polish adjusted areas to a high shine polish, using zirconia polishing cups or points.
• Avoid carbide use

Zir-MAX.M e® is a good material choice for patients that desire a bright color/high-value all-ceramic but want natural translucency as well, especially when the patient requires more strength. Zirconia can be fabricated with very high-value effects but still provide an esthetic translucent incisal edge. Many other ceramic material choices can gray unsatisfactorily as translucency is added; zirconia is less inclined to develop undesirable grayness. This facilitates the creation of a “Hollywood White” with a natural incisal translucent effect. The additional translucency of  Zir-MAX.M e®  over previous zirconia materials yields a more vital restoration while achieving the brightness of a Hollywood Smile.
