The competitive price, lightness and ease of maintenance of the Black Pearl Eco ensure it stands apart. If this were not enough, its power has been increased by more than 50%. It has one separate air/water spray and connects directly to a 2-/3-way or 4-way hose. Its moderately sized head makes this the versatile turbine par excellence.

Type 801-801L: Cavity burs

To treat decays, amalgam or composites cavities.
Remastering of fissures after preparation with plastic filling or ceramic inlays.

Small diameter:
– To eliminate decay from sulcus and decay infiltrated in pits and fissures.
– For small decays close to incisors and canines that require tiny and retentive cavities.
– For cavity retentions in those teeth with bigger decays.

Big diameter:
– to eliminate badly decayed cavities, essentially on (018-021) molars or for concave shaping of crowns in the incisal area (029-035) allowing an optimal stress distribution.



Type 802: Cavity preparation class I-III (plastic filling materials)

The cylinder diameter allows to get straight walls, whereas the round bur enlarges the retentive cavity in depth, according to the decay destruction shape.
