The centrifugal force generated by a normal 360º turn prophy angle results in splattering and mess. The 60º turn reciprocating prophy angles eliminates potential splattering of prophy paste, blood and saliva, keeping the prophy paste in the cup where it belongs. Less reciprocating means much less heat during use, assuring a smooth, cool treatment for your patient. Due to less heat generated during use, if necessary more pressure may be applied to remove stubborn stains. With it's innovative design the prophy cup or brush can be used continuously on the tooth surface, saving valuable chair time. The rotational motion of traditional prophy cups and brushes can cause laceration and bleeding of the gums.
