70% more power—much greater power than a Universal or Perio insert. Robust enough to smooth plaque-trapping overhangs and remove proximal accretions and stubborn cements. Silicone grips insulate against vibration and heat transfer. Soft-grip provides more comfort and lessens finger vibration. Specialty: Higher vibration compared to all other inserts when using maximum power level. Primary Use: Moderate to extra heavy supra and subgingival deposits. Power: Any. For use in Parkell’s 30KHz and all 30KHz compatible scalers. Durable construction – inserts last longer.
