handpiece, I think you would be hard pressed to come up with a more comfortable design than the folks at Hu-Friedy did. I find that the large diameter handpiece keeps my hand relaxed, so I avoid the kind of muscle strain and hand fatigue that I often experience when trying to hold a handpiece. It also has a fiber-optic light source, so you can see what you are doing. Now make this a piezoelectric scaler and you have a winner in your hand. My hygienists have been using piezoelectric scalers for over 15 years, and they will not switch. When I gave them the Symmetry IQ to evaluate, they were thrilled with the truly user-friendly touch pad controls that have three color-coded, predefined power settings for a variety of scaling procedures. The unit has a smooth, easy-to-clean surface that makes infection control easy. Of course, Hu-Friedy has designed an IMS™ cassette specifically for the Symmetry IQ handpiece. The cassette is available for double or single handpieces. Add to all of this Hu-Friedy’s 100 years of experience in designing and making scaling tips, and you have the Symmetry S-Series Piezo Tips. They offer a comprehensive group of tip designs that are made to work with the Symmetry IQ generator. Included are a universal standard diameter tip for removing heavy supragingival deposits, a thin perio tip, a curette style tip, and a diamond-coated tip for removal of residual debris. Last but certainly not least, the Symmetry Piezo Tips come with the patented Guardian™ Tip Carrier, which is a great torque-limiting wrench designed for safe and easy connection of the tip to the handpiece. The bottom line is that my hygienists gave this piezoelectric high marks as a great device. They definitely want one of them.
