ProAngle Ergo’s shell is ergonomically designed for ease of use. Its tilted head allows hand and wrist to operate with less effort compared with traditional prophy angles, causing fewer micro-traumas. The gearing structure of ProAngle Ergo makes it much quieter than other contra-angle DPAs. The newly developed Torque Cup effectively reduces splattering with its blade geometry and features outer diamonds for improved interproximal cleaning.
