Delivering Strength and Esthetics with Obsidian® Fused to Metal – Case of the Week: Episode 191

For the Case of the Week for “Chairside Live” Episode 191, I turned to a state-of-the-art PFM solution to address a heavy bite. The patient, Maria, joined Glidewell Laboratories a year ago as a senior regulatory affairs specialist, a role in which she maintains the company’s strict compliance with all national and international regulations. Her case is emblematic of our culture at Glidewell, where employees are able to contribute to the dental industry and also receive dental work that embodies the latest materials and techniques available.

Maria’s previous restorations included a metal-occlusal PFM on one tooth and chipped porcelain on another; in planning her new restorations, I prioritized masticatory forces as a chief concern.

In addition to using a material that would be able to resist heavy bite forces, I wanted the new restorations to show ideal esthetics, which were lacking in the original PFMs. Of course, the old restorations’ inadequate esthetics were not surprising, as traditional metal occlusal PFMs require some compromise: Strength is maximized, but esthetics suffer.

Fortunately, Obsidian® Fused to Metal (Glidewell Laboratories; Newport Beach, Calif.) avoids this compromise. Offering superior chip resistance, an average flexural strength of 397 MPa, and a lifelike appearance, Obsidian sets a new clinical standard for PFMs. Read on to see how this material yields esthetic, strong restorations.


In the past, a case like this required traditional PFMs, which maximize strength but don’t deliver ideal esthetics. However, that tradeoff doesn’t exist in this case, thanks to Obsidian Fused to Metal. As a cutting-edge update of the long-standing PFM solution, Obsidian Fused to Metal raises the standard in every regard. The material’s flexural strength, chip resistance and ideal esthetics mean that clinicians can count on Obsidian for durable, lifelike restorative results.
