Monolithic Zirconia Restoration

“The physical properties that make zirconia appealing as a restorative material also necessitate that it be properly finished with meticulous attention to detail. It is important that you work with a lab you can trust to do that.”

Derrick Luksch, CDT | Owner

Monolithic Zirconia Restoration

When fabricated as a monolithic restoration, zirconia has the highest flexural strength and fracture toughness of any tooth colored material. When properly polished by the dental laboratory, zirconia restorations achieve an extremely smooth surface texture that is kind to opposing dentition. These physical properties have made monolithic zirconia restorations a popular alternative to cast alloy restorations in the posterior region.

Indications & Recommendations

Zirconia is indicated for crowns and bridges anywhere in the mouth. However, due to the optical properties of the material, we recommend its use be limited to posterior restorations.


Occlusal*: In order to maintain the extremely smooth occlusal surface of polished zirconia, care must be taken when making occlusal adjustments. For minor occlusal adjustment, it is recommended to adjust the opposing tooth. If that is not possible, the Brasseler Dialite Intral Oral Adjustment and Polishing Kit provides the necessary instruments for reducing zirconia. To properly polish zirconia, the restoration must be polished with a diamond polishing paste.

Internal: For minor adjustments, it is recommended to adjust the preparation. If the internal aspect must be altered, a sharp diamond with irrigation is recommended to minimize the generation of heat.

*Failure to achieve a mechanical polish of zirconia restorations, by the lab or dentist (after adjustment), can be detrimental to opposing dentition due to the hardness and abrasiveness of unpolished zirconia.


Monolithic zirconia restorations can be conventionally cemented with your crown and bridge cement of choice. Due to its crystalline structure, zirconia crowns cannot be etched and therefore cannot be adhesively bonded. For increased adhesion through chemical bonding, Multilink® Automix by Ivoclar is recommended.


All restorations are manufactured in our laboratory in Corvallis, Oregon under our ISO 9001:2015 and DAMAS Quality Management System guidelines. This ensures your patients consistently receive only the highest quality restorations. Production time is five working days in the laboratory.

Crown & Bridge

Monolithic IPS e.max Press fabricated with TRUfit® technology. The ultimate combination of fit, beauty, and durability in your lithium disilicate restorations.

We developed a restoration that improves the esthetics of monolithic zirconia without compromising its advantages. We call it Micro-Layered Zirconia.

Monolithic zirconia restorations (MZR) is a metal-free, tooth-colored, alternative to full cast restorations.

Porcelain Fused to Engineered Zirconia

Conventionally layered porcelain build-up over a high-strength ceramic coping or framework. Highly esthetic and conventionally cementable.

Porcelain Fused to Metal

PFMs manufactured with our proprietary TRUfit system for improved fit, marginal accuracy, and optimal porcelain support.

Full Cast Gold

Still the benchmark by which all other restorative materials are measured. Our full cast restorations benefit from the use of our proprietary TRUfit® system.

Removable and Implants

Complete Dentures

A natural-looking, well-fitted, and properly functioning denture can significantly impact a patient’s life.

Removable Partial Dentures

Quality is critical to successfully treating patients with an RPD. Quality comes down to three things: the design, the frame, and the acrylic work.

Implant Dentures

O’Brien has been at the forefront of the implant denture field for over 25 years. Whether the cases are implant retained or supported, we have the education and experience to meet your needs.


Night guards and bite splints are indicated in a wide variety of conditions. Thermo-Splint offers ease of use and maximum comfort increasing patient compliance.

Sports Mouth Guards

A custom Sports Mouth Guard minimizes the risk of oral trauma and provides improved comfort compared to stock appliances.

Implant Restorations

Implant restorations are some of the most complex cases we work with at O’Brien, but fortunately we have the expertise to meet your implant restorative needs.
