Make your present handpiece 50 percent lighter with the esa (extended straight attachment) disposable prophy angle. Less weight makes esa easier on your wrists and hands, making you feel a whole lot better at the end of the day. Think about never having to clean, lubricate and autoclave a straight attachment again. And when you consider the cost of cleaning and autoclaving, esa actually costs less to use than other disposable prophy angles with traditional handpiece connections. Esa attaches to the Star® Titan handpieces.
