Martin Curettes Fig.3

The Martin Curettes Fig.3 is a double-ended sinus curette with mirror-image working ends, each measuring 4.0 mm in width as confirmed by the LS1-290 article reference and blade dimension marking visible in the product image. Both blades carry a concave spoon-shaped cup with semi-sharp rim edges, mounted on terminal shanks that angle in opposite directions on each end — providing two distinct approach vectors from a single instrument during membrane elevation. The round ringed knurled handle is machined from AISI 420 surgical-grade stainless-steel, allowing stable axial rotation between two fingers throughout the working sequence. Overall instrument length is 165 mm (6.5 inches), balancing consistently at mid-handle during active strokes.

The 4.0 mm blade width positions the Sinus Lift Instrument Fig.3 as the wider follow-up to the Fig.2 variant, covering the expanded subantral space after the initial membrane release has been established at the window margins. The semi-sharp rim edges scrape along the cortical sinus floor surface while the concave blade face lifts and holds the Schneiderian membrane upward without generating perforation risk at the blade center. The stainless-steel body tolerates autoclave sterilization at 134°C across repeated cycles without shank distortion or tip oxidation.

Oral surgeons and implantologists use Martin Curettes Fig.3 during lateral window sinus floor augmentation when posterior maxillary bone height falls below 5 mm. After the Fig.2 establishes the initial release, the clinician switches to this 4.0 mm blade to widen membrane elevation across the sinus floor, distal wall, and medial sinus wall in short sweeping strokes before graft material placement and collagen membrane coverage.

Every instrument that carries the Leader Surgical name goes through the same manufacturing standard — no shortcuts, no variation, and no compromise on what gets handed to a surgeon.

What is the primary function of a Fig. 3 Martin Curette?
It is a surgical hand tool designed for debridement, specifically for scraping, cleaning, or removing diseased tissue and bone fragments. Commonly used in orthopedics for bone grafting and joint reconstruction, and in dentistry for alveolar socket cleaning and cyst removal.
