Abstract
A splatter guard for a dental cleaning tool eliminates the splatter by gathering splatter first on the outer lower one-third to one-half of the fructoconical prophy cup using combination of vanes and the dimples. As the splatter migrates upwards, the splatter guard wipes off the splatter. The reason the splatter guard is constructed smaller than the cup is because it allows the cup to flex outward without interfering during use thereof. The splatter guard can be attached several different ways, including slide in, snap on, secured between two half-housing members, or formed integrally with the housing, for example. The drive train is housed in a partial split contra angle housing which allows accurate positioning of the gears as it is required to ensure that the cup rotates concentrically and remains in touch with the knife edge of the splatter guard.
