From the milestone website. "New from Milestone Scientific, SafetyWand is the revolutionary answer to the federal legislation* requiring safety engineered devices for dentists. The unique auto-retracting design shields the needle while you’re not using it.
SafetyWand is safer and lighter than a traditional syringe and is operated with one hand. The pen-like grasp provides optimal ergonomics allowing maximal tactile control. And, the best news is that SafetyWand is part of the CompuDent computer-controlled local anesthetic delivery system.
CompuDent with SafetyWand is ideally suited for all injections and procedures and is easier to handle, easier to anesthetize and is now SAFER than ever.
It’s just easier and SAFER - Period."
