The Next Generation in Scaling:

The Game Changing Double Graceys

A revolutionary concept and design conceived by Dr. Clayton Gracey in the 1940’s, the Gracey line of hand instruments are celebrated as the “Queen Bee” of all hand instruments.Hygienists know that when we pick up a Gracey, it will instrument periodontal pockets greater than 3 mm better than any universal could. When I attended the University of Iowa dental hygiene program, this was repeated until it was ingrained in our heads. Recently, I had the opportunity to teach a couple of hands-on instrumentation courses in my Alma mater state, where other University of Iowa grads confirmed my suspicion. Turns out, many of us are loyal Gracey fans.

As a typical, detail oriented hygienist, I have subscribed to this thinking and had success improving the health of my patients. There were, however, several time management issues with this method. First, I was often running behind, picking up and putting down multiple instruments for each specific area is time consuming. The other, has been the challenge of re-sharpening Graceys. Keeping up with every Gracey, in every cassette, is a daunting task.They were often too dull to do the excellent job I expected of them. If they were sharp, who knows what kind of angle I had created in my haste to craft a sharper edge? Then there is the reprocessing. It takes time for big cassettes to run through, and sometimes, I didn’t have enough for the day. What to do? Order more set ups and send them out for sharpening? That’s expensive .Build in time to sharpen? Also expensive, and pretty darn unrealistic.

Three years ago, my game changed forever. I experienced an advancement in scaling that satisfies my need for Gracey coverage, while also solving the expense and time management issues they created. Enter the world-shattering American Eagle XP® Technology Double Graceys. Only two instruments are needed to access the ENTIRE mouth? NO WAY!

How does this work? Sounds like tissue trauma in the making, right? Not at all. The specially designed face of the blade comes to a peak that creates a 70-degree angle on each side. Insert the Double Gracey into the pocket, just as you would any Gracey, and you will find the shank is just off parallel of the long axis of the tooth when you feel the blade “bite.” A rounded toe and back, protects the wall of the pocket from tissue trauma, just as any Gracey would. To watch the Double Gracey in action, view this video:

Just when I thought I had found Gracey utopia, I had the chance to try a set of Double Gracey mini’s. These babies are 3mm longer in the shank, with a 50% shorter working blade. I have detected fossas and concavities that I didn’t know existed with these very unique instruments. XP Technology sharpen-free instruments are designed to not be re-sharpened. By this, I mean they are shipped from American Eagle Instruments’ factory in Montana, with thinner blades…15% thinner than stainless steel instruments to be exact. For the first time in my dental hygiene life, my instruments have a completely unaltered factory edge for their entire working life! What a concept! Even though I preferred the thinner blade on my past stainless steel instruments, I probably had redesigned the working angle of the blade a bit. Most of us are not as proficient at sharpening as we think. Read this excellent study done by Lory Laughter, RDH, MS to see what really happens when most of us try to sharpen:

If you are looking for a way to elevate your dental hygiene game, give the Double Gracey Kit a try.The kit contains both Double Gracey minis and both regular Double Graceys.You can check them out here:
