For the removal of supragingival calculus.
For calculus removal place the tip third of the scaler’s cutting edge against the tooth. Tilt the instrument toward the tooth to achieve 70° to 80° angle between the tooth and the blade. Apply lateral pressure and activate the scaler by using vertical, diagonal or horizontal pull strokes. To maintain control use short 2-3 mm long strokes.
Same angle but with a more delicate blade than in the Crane-Kaplan.
