“With Enamelux, my goal was to provide our customers with the highest quality and most consistent lithium disilicate restorations our laboratory could produce. To date, we’ve manufactured more than 81,000 Enamelux restorations with a 99.49% success rate. According to our records, that makes Enamelux our most successful ceramic restoration.”

IPS e.max®

IPS e.max* Press lithium disilicate is our preferred choice of restorative material, and there are several ways to fabricate and finish the various formulations of the product. IPS e.max has more than ten years of clinical reliability and is a trusted solution for dentists worldwide. Lithium disilicate rivals the beauty of the best metal-free materials available today, and through our patented TRUfit processing technique, Enamelux restorations provide exquisite results.

Manufactured with TRUfit® Technology

IPS e.max Press lithium disilicate restorations are manufactured by the lost wax method. We developed a manufacturing system for making lithium disilicate restorations, and hold three patents on this innovative precision manufacturing system we call TRUfit.

We use our patented TRUfit system to fabricate our lithium disilicate restorations using IPS e.max Press and we call the resulting restorations Enamelux® lithium disilicate restorations.

Our process utilizes industrial-grade milling equipment and tooling to produce our wax patterns. This system yields a restoration with superior fit, precise margins, and natural-looking anatomical contours. When it comes to lithium disilicate restorations, utilizing TRUfit technology yields quality and consistency unachievable via hand-wax or milled methods of manufacturing, resulting in few chairside adjustments.

Indications & Recommendations

Enamelux restorations are recommended for inlays, onlays, veneers (to .4mm thin), crowns, and three unit bridges to 2nd bicuspid. Maximum pontic span of 9mm in posterior and 11mm in the anterior, and interproximal connector size of 16 square mm, is recommended.

Preparation/Dentin Shade

Given the varied indications and translucency of the material, a preparation or dentin shade must be provided for optimal esthetic results. This is best communicated utilizing the IPS Natural Die Material shade guide by Ivoclar.

Production time is seven working days in the laboratory.


Crowns may be bonded or conventionally cemented based on material thickness of the finished crown. For restorations that meet the preparation criteria of a minimum 1.5mm occlusal thickness, conventional cementation is possible. If the minimum thickness is at all compromised adhesive cementation is advised. Note: Because studies have shown that adhesive cementation almost doubles the static load-bearing capacity of a lithium disilicate restoration, and gives your patient the most dependable product possible, our recommendation for all posterior restorations is adhesive bonding.

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.
