Sc2 Sinus Curette

The Sc2 Sinus Curette is a double-ended surgical-grade stainless steel sinus membrane curette with two asymmetrically sized working ends. The 3.3mm narrow blade addresses anatomically restricted sinus floor regions and tight window access points, while the wider opposing end covers broader membrane surface area during progressive elevation. Both blades carry dull, atraumatic concave faces specifically designed to prevent cutting into the Schneiderian membrane during separation strokes. Both ends are set on angled shafts offset from the full-length ringed knurled handle for access control throughout the procedure.

The 3.3mm blade width is narrower than the standard ISSC1’s 3.5mm, making the Sinus Curette 2 SINC2 specifically suited to narrower sinus floor zones, septa-adjacent anatomical regions, and cases where a finer curette face is needed to maintain controlled bone contact without membrane compression. The dull blade design on both working ends protects the Schneiderian membrane from inadvertent laceration during deliberate scraping-elevation strokes. Both ends tolerate full steam autoclave sterilization at 134°C without blade deformation or handle degradation.

Oral and maxillofacial surgeons and implantologists use this sinus floor elevation curette during the lateral window maxillary sinus floor augmentation procedure. The narrow 3.3mm end separates the membrane from anatomically confined sinus floor regions, septum borders, and anterior wall junctions where wider curettes lose bone contact. The wider end then extends coverage across the broader central and posterior sinus floor, reflecting the Schneiderian membrane away from the bone to create the sub-membrane space required for bone graft placement before posterior implant insertion.

Leader Surgical recognizes that sinus augmentation demands curettes matched precisely to anatomy, which is why the Sc2 delivers a narrow-to-wide blade range that works where standard curettes simply cannot.

What makes the “SC2” version specific?
The SC2 typically features a long blade and specific tip widths (often 3.5mm or 2.8mm/5.0mm) designed to access deeper inner spaces that shorter or wider curettes cannot reach as effectively.
