Long blade ISSC1 SINUS LIFT

The Long Blade ISSC1 Sinus Lift is a double-ended sinus lift curette constructed from surgical-grade stainless steel, with identical 3.5mm wide working blades on both ends. Each blade features an extended long shaft set at an offset angle from the handle axis, with a concave spoon-shaped inner face and a smoothly curved atraumatic tip. The extended blade length distinguishes this instrument from the standard ISSC1, providing additional reach for accessing the deep posterior and medial walls of the maxillary sinus cavity during lateral window augmentation procedures.

The concave blade geometry allows the surgeon to slide the working face along the inner sinus floor without applying direct apical pressure against the Schneiderian membrane. The Sinus Lift surgery with bone graft instrument’s full-length ringed knurled handle transmits clear tactile feedback when the blade contacts bone versus membrane, supporting controlled incremental elevation. Both working ends are mirror-image configurations, allowing the surgeon to use either end without repositioning. The instrument tolerates full steam autoclave sterilization at 134°C and standard ultrasonic cleaning without blade deformation or handle degradation.

Oral and maxillofacial surgeons and implantologists use this Sinus grafting for dental implants instrument during lateral window maxillary sinus floor augmentation. After creating a bony access window on the lateral sinus wall, the surgeon introduces the long blade to separate the Schneiderian membrane from the sinus floor and extend the elevation to the anterior, posterior, and medial walls of the sinus cavity. The created sub-membrane space is then filled with autograft, allograft, or xenograft bone graft material before posterior implant placement.

For implantologists who work in anatomically complex posterior maxillary sites where standard curettes fall short of the medial wall, Leader Surgical provides the extended-reach solution that makes the difference between a completed elevation and a compromised one.

What are the two types of sinus lifts?
There are two forms of sinus elevation surgery: an internal sinus lift and an external sinus lift. The type of sinus lift required depends upon the amount of native bone present at the time of surgery.
