The micro tips H3 and H4 with curette have shape double guiding edges to remove calculus and deposits with no risk of damage to connective fibers. They are designed for deep and narrow pockets debridement.

The diamond-coated micro-tips H1 and H2 are used in the second step for root planning, treatment of furcations and abscesses and to remove granulation tissues. They must be inserted delicately, without pressure (approximately 0.3N), to avoid over-instrumentation.

The micro-tips operate in the opposite direction to manual curettes (i.e. using a push stroke without scraping), from the sulcular opening towards the bottom of the pocket without excessive lateral pressure. Residual deposits are removed from pockets and cementum surfaces are decontaminated by the bacteriostatic effect of micro-cavitation.
