The award-winning Multi-Axis Spiral Suction (MASS) tip features a spiral vented design, angled barrel wall, and a rolled edge. It is the FIRST & ONLY HVE tip that; prevents soft tissue from being drawn-in, allows for continuous suction even if the end of the tip is occluded, prevents backflow of fluids, and serves the function of both an HVE tip and a saliva ejector. In addition to those features it offers; a more ergonomic hand positioning for assistants, a better field of view for both dentist and assistant, is quieter than traditional HVE tips, and has a rounded edge to prevent possible tissue trauma. -- 100 disposable tips per bag.
