I am dissatisfied with my electric high-speed handpiece. It was expensive to purchase, and yet it breaks frequently and is also very expensive to repair. Can you recommend a high quality air-driven handpiece that is ergonomical and easy to maintain?

I would recommend the SolaraPlus (DentalEZ) high-speed air-driven handpiece for several reasons. It is solid titanium and very light (36 g), thereby reducing hand fatigue. It is also easy to maintain because it has a lube-free ceramic ball-bearing turbine. It also features solid, glass rod fiber optics, a four-port water spray, and more than 18 watts of power for efficient cutting.
