PDT Gleason Guide™ Sharpening System

PDT Gleason Guide™ Sharpening System


Take the guesswork out of sharpening for more accurate results in less time, every time.

Let’s face it — sharpening dental instruments isn’t the best part of anyone’s day. Maintaining that perfect edge while thinking about the clock is a struggle that every dental professional is familiar with. That’s why PDT is proud to bring you the patented Gleason Guide™ Sharpening System!

See How It Works With PDT CEO and Founder Linda Miller

By following a simple 3 step process, you can maintain your edge easily and quickly:
  1. Stop. Place the back of your instrument’s blade against the stop.
  2. Rest. Lower the instrument until the terminal shank is resting against the bar.
  3. Glide. Move your instrument in a gliding motion across the stone using light pressure.

Using the Gleason Guide to maintain your dental scalers, curettes, and Graceys is just that easy! By keeping your dental instruments at their best, you can reduce chair time and improve comfort for patients. Plus, a sharp instrument reduces the amount of pressure you need to apply when removing deposits, gives you more control over the instrument by reducing slipping, and improves your ability to detect calculus.


Why is sharpening important?

  • Reduce the number of strokes necessary to remove calculus, leading to a more comfortable visit for your patients and greater efficiency.
  • Lessen the amount of pressure needed to effectively remove calculus, reducing the risk of developing musculoskeletal disorders.
  • Avoid burnishing calculus for more effective patient treatment.

Ultimate Edge Sharpening Kit™


Includes everything you need for regular maintenance of your dental instruments. PDT’s fine ceramic sharpening stone helps maintain your instruments edge by removing only small amounts of metal during restoration. This helps keep your instruments sharp, and increases their longevity.

Ultimate Edge Transformation Kit™


This kit not only includes our fine stone for regular maintenance, but also a coarse ceramic sharpening stone meant for reshaping and re-beveling blades on instruments that have gone too long without resharpening. By taking more metal off with each stroke, you can use the combination of the stone and Gleason guide to help restore proper instrument edge and sharpness.

Frequently Asked Questions

While the Gleason Guide helps definitively answer how to sharpen your instruments, why and when to sharpen aren’t always so straightforward.

Whether an instrument relies on special coatings or sound metallurgical processes, no instrument can stay sharp forever. As you run a sharp edge over a hard surface, the edge will round and wear slightly with each stroke. Over time, those small changes add up, forcing you to apply more pressure to the instrument to get it to cut properly. This gradual wear can be hard to spot, leading to more discomfort for both you and your patient and a higher chance of burnishing calculus.

By creating instruments that not only hold their edge but can also be resharpened, plus a sharpening system that’s easy to use, PDT has designed a system for high-quality instruments that provide real longevity and comfort.

While many practitioners try to do their sharpening on a weekly or daily basis, sharpening your instruments should be based on use rather than time. There are two common ways to check if your instrument is still sharp: the visual glare test or through the use of a test surface like PDT’s PingRing™.

The visual glare test involves evaluating the light reflection off the junction of the face and the lateral side of the blade. If light reflects at that point, then you know you need to resharpen. If you can’t see that reflection in the edge, then you know it’s sharp.

To test the sharpness with a PingRing™, place your blade at the angle you would be using it on a tooth. Then, use your fulcrum and apply a normal amount of pressure. The blade should grab the surface and you’ll hear a pinging sound that tells you the edge is sharp. If the instrument slides across the ring, then you know that it’s time to resharpen.

At PDT, we use ceramic sharpening stones because they’re harder, leading to greater longevity. Plus, you don’t have to use oil or water when you’re sharpening with them. By combining durability with convenience, our ceramic stones don’t become a hindrance to maintaining a regular sharpening schedule.

Yes, it can. The Gleason Guide’s sharpened bevel is based off the terminal shank, so any scaler, curette, or Gracey can be sharpened effectively with the Gleason Guide regardless of manufacturer. Keep in mind that some instruments use coatings to maintain their edge, and may not be able to be safely resharpened. Always check a manufacturer’s guidelines before using any sharpening method with these types of instruments.
