  • Patent number: 10092382
    Abstract: A disposable prophy angle is provided, the prophy angle comprising a housing containing a drive shaft and a driven shaft; the drive shaft having a proximal end and a distal end and a longitudinal axis therebetween, the distal end having a substantially conical driving portion and a projection, the proximal end of the drive shaft configured to engage a dental hand piece; and the driven shaft having a driven portion comprising a recess configured for engagement by the projection and/or the substantially conical portion of the drive shaft to oscillate the driven shaft at an oscillation angle greater than 90 degrees. In some embodiments, there is a method of making a disposable prophy angle by overmolding a prophy cup to the prophy angle. In other embodiments, there is a method of using the prophy angle to prevent tooth decay.
