BONE SCRAPER STRAIGHT & CURVED SET
Dual-geometry cortical bone harvesting set designed for atraumatic collection of autogenous bone shavings in regenerative procedures.
Key Features:
• 2-piece set: straight scraper (LS9-276) and curved scraper (LS9-277)
• Straight axial blade for direct cortical bone harvesting on flat surfaces
• Curved offset blade for access to anatomically restricted or concave areas
• Sharp precision-ground edges for controlled bone shaving without fragmentation
• Produces thin cortical shavings with higher biological viability than milled bone
• Multi-ring ribbed handle for secure grip and controlled scraping motion
• Single-piece surgical-grade stainless steel construction for durability
• Autoclavable at 134°C with ultrasonic cleaning compatibility
BONE SCRAPER STRAIGHT & CURVED SET
The Bone Scraper Straight & Curved set (Article# LS9-276 / LS9-277) comprises two single-ended instruments machined from surgical-grade stainless steel. LS9-276 carries a flat, thin rectangular blade with a sharpened leading edge aligned axially with the handle for direct straight-line cortical bone collection. LS9-277 features a laterally offset curved blade geometry, angled to access bone surfaces that resist straight-line instrument approach. Both instruments share a multi-ring ribbed cylindrical handle that delivers a firm rotational and push-pull grip during active scraping strokes.
The sharpened blade edge on each instrument is ground to maintain a consistent cutting angle against cortical bone surfaces, producing thin shavings rather than fragmented particles, a clinically important distinction, as intact shavings retain greater cell vitality than milled or ground bone. Both instruments tolerate steam autoclave sterilization at 134°C and ultrasonic bath cleaning with neutral-pH detergents. The single-piece stainless steel construction eliminates joint failure points and simplifies reprocessing, with no internal cavities where bone debris could accumulate.
Oral surgeons, implantologists, and periodontists use this autogenous bone harvesting tool during guided bone regeneration, ridge augmentation, sinus floor elevation, and socket preservation procedures. The straight Bone scraper is drawn across accessible flat or slightly convex cortical surfaces, typically the external oblique ridge, buccal shelf, or retromolar area, while the Bone Scraper Curved navigates anatomically restricted concave sites and posterior regions where axial blade alignment is impractical, ensuring complete harvest from irregular bone surfaces.
Good bone grafting outcomes begin long before the graft is placed, they begin with the quality of the harvest. Leader Surgical designs both variants of this set with that truth in mind: sharp, reliable instruments that protect cell vitality and give surgeons the access they need, wherever that access happens to be.
When should I use a Straight vs. Curved scraper?
- Straight: Best for easy-to-access, flat donor sites like the chin (symphysis) or the body of the mandible.
- Curved: Specifically designed for contouring around concave or convex surfaces, such as the external oblique ridge or the ramus, where a straight tool may lose contact with the bone.
