NeoDiamond Z-Class Adjusters Evaluation
Durable, single-patient-use diamond burs easily and efficiently cut and adjust zirconia restorations, reducing overall procedure time
Toddlers and teenagers are notorious for being difficult. But with the right tools and perseverance, both parents and their offspring can survive those challenging years. Like children, zirconia is a dental material that’s infamous for being difficult. The same qualities that make zirconia an excellent choice for restorations, namely exceptional durability and strength, make the material extremely challenging to cut, adjust, and polish—sometimes resulting in less-than-ideal final esthetic results.
Yet with the right instruments in hand—for example, Microcopy’s NeoDiamond Z-Class diamond burs—dentists can not only survive the often-dreaded zirconia adjustment process, but perhaps even enjoy it. Dr. Robert DeFazio recently discovered the Z-Class diamonds, which are designed specifically for cutting and adjusting zirconia, and declared, “These burs were phenomenal!” He said they easily reduced the restorations and, when combined with polishers, left a very smooth and esthetic finish.
For this DPS evaluation, Dr. DeFazio and several other dentists used the single-patient-use Z-Class Adjusters in combination with Microcopy’s NeoShine Zirconia Polishers. “I was placing an implant crown on my best friend’s mother, and the Z-Class Adjusters worked perfectly,” said Dr. DeFazio. “It required less chair time to achieve a superior finish. I would highly recommend them.”
Single-Patient-Use & Variety of Shapes
Like all NeoDiamond burs, Z-Class diamonds are enclosed in sterile packets designed for single-patient-use to avoid cross-contamination and encourage safer dentistry—a timely message given how the recent pandemic has impacted the dental industry. With 10 shapes in total—7 adjusters and 3 cutters—Z-Class provides dentists with the tools they need to tackle zirconia restorations with confidence.
Dr. Marc Hendler said the 7 different shapes in the Z-Class Adjuster portfolio—round end taper, ball, teardrop, needle, egg, flame, and pointed cone— “are more than adequate” for all of his zirconia adjustment needs. Citing the variety of shapes and ease of use as his favorite features, Dr. Ken Bendik said he was very happy with the performance of the adjusters and was pleased with the final results.
“The shape of the egg diamond was perfect for occlusal adjustment, and the unique cone-shaped polisher made getting into the grooves and anatomy of a tooth far easier than I would have expected,” shared Peter Dantini Jr., DDS. “Between the shape of the egg adjuster and the 2-step NeoShine polisher, I found it far easier to achieve a polished crown than when using my [other] wheels/points and diamonds.”
Ease of Adjustment & Polishing
Created with unique zirconia-grade diamonds, Z-Class Adjusters are designed to produce a smooth cut at a consistent depth without scarring, according to Microcopy. Without deep striations in the adjusted surface, polishing occurs quickly, improving efficiency and ultimately creating an esthetic, durable final zirconia restoration.
The Z-Class Adjusters “did a great job of adjusting zirconia, which in general is a very difficult material to cut,” noted Leonard Tau, DMD. “This product does exactly what it’s supposed to do—make adjusting zirconia easier,” he added. “In cases where it’s difficult to adjust a solid zirconia prosthesis, it resulted in easier adjustment and superior polishing,” agreed Dr. Kenneth Chae. “Regular diamond burs do not work well on zirconia, but the Z-Class Adjusters reduced high spots on zirconia crowns without burn marks or the need to worry about fracturing the crown,” explained Dr. Gary Dong. He called it a good product that reduces interferences, makes adjustments easier, and, after polishing, offers ideal esthetics.
Time Savings & Final Results
“The Z-Class Adjusters made rapid and clean adjustments of zirconia possible,” reported Dr. Louis Sterling, who said the diamond easily cut through porcelain while removing a fixed bridge. “The polishers provided a high gloss finish after the diamonds were used, resulting in a simple, easy, nice final restoration,” he added. For Diane Casey, DDS, “The adjustments were so smooth that minimal polishing was required,” saving overall procedure time. She said the sterile packaging is simple, making the burs easy to store, dispense, and use.
Dr. Mark Vidor said the diamonds made procedures quicker and more efficient, and Dr. Hendler said he liked the speed, high luster, and excellent results of the NeoShine polishers after using the adjusters. Dr. DeFazio noted, “I loved the finish. It was beautiful,” and Dr. Dantini concluded, “The quality, durability, and finish is outstanding for a diamond and 2-step polisher.”
Dr. Hendler said he liked the Z-Class Adjusters so much that he would be a spokesperson for the product, and Dr. DeFazio said he has already recommended the adjusters to friends. Noting that it is an “economical, convenient, and overall good product,” Dr. Casey concluded, “Zirconia crown delivery was made easier with burs and polishers specifically designed for this task!”
