ZCore+

Porcelain Fused to Engineered Zirconia

“ZCore+ is a great alternative to anterior porcelain to metal restorations. I would recommend them for anterior crowns and bridges with the most demanding esthetic requirements.”

Karli Luksch, CDT | Senior Team Leader

Porcelain Fused to Engineered Zirconia

Over the years, Zirconia has proven to be sufficiently strong when used as a core material. However, due to a number of differences in the handling characteristics of zirconia versus metal alloys, the structural makeup of veneering porcelain is significantly different. As a result, while zirconia porcelain is very esthetic and kind to opposing dentition, it does have a fracture toughness that is 33% lower than porcelain used for PFMs. Therefore, copings and frameworks that provide optimal porcelain support are crucial to the durability of zirconia-reinforced restorations. Clinical studies, as well as our own observations based on 50,000+ units fabricated over the past 15 years, reveal that there is a higher incidence of chipping of the veneering porcelain with these restorations.

Indications & Recommendations

Although many manufacturers advocate the use of porcelain fused to zirconia restorations in all areas of the mouth, we recommend restricting their use to single crowns and 3-unit bridges in the anterior region. Cases involving posterior teeth can only be recommended with prior case consultation and evaluation.

Cementation

ZCore+ 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.

Workmanship

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 seven working days in the laboratory.

Multilink® is a registered trademark of Ivoclar Vivadent, Inc.

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.

Thermo-Splint

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.
