Ultrasonic scaler inserts provide the active tip for ultrasonic and magnetostrictive systems. These inserts fit in the handpiece and are vibrated to provide the power scaling and other treatments used with these systems. Scaler inserts are available in a range of sizes and they are designed to work at specific frequencies, so it's important to have the best insert for the system you use and the case you are treating. These ultrasonic tips are also available with different angles and some include swivels to make them easier to maneuver during treatment.
