How to use the Tip Card
1) Place the neck of the Tip in the cut out.
2) Check wear of the Tip.

we recommend to replace a Tip when the Tip meets the yellow line (wear of 1mm) to guarantee safe and
effective use.

25% when the top of the Tip wears 1 mm
and approximately 50% when it wears 2
mm. In addition, the vibration condition
changes owing to the wear, which may
damage a patient's tooth surface. Check
the Tip wear condition with the Tip Card
periodically, and replace the Tip with a
new one in good time.
