Designed with TrueFit Technology to provide real ergonomic benefits driven by scientific evidence. This advanced, sensor-based testing system measures over 2.8M data points for pinch force in the finger and pressure applied to the tooth when scaling. The optimized shape, with double-helix grip, reduces pinch force up to 65%. Its optimal proportions and ideal width provide increased patient comfort by applying 37% less pressure to the teeth. Features EverEdge 2.0 working ends that are 72% sharper than the next leading competitor. This allows clinicians to efficiently remove calculus while applying less pressure to the handle, thereby creating a more comfortable experience for both them and their patients.
