90 Lucas Spoon Shape Curettes

The 90 Lucas Spoon Shape Curettes is a double-ended instrument with mirror-image spoon blades, each measuring 4.0 mm in width as confirmed by the LS1-299 article reference and blade dimension marking visible in the product image. Both working ends connect to terminal shanks angled at 50 degrees with a 21 mm reach, directing the concave spoon face squarely against large molar socket walls without handle interference on adjacent teeth. The round large-diameter handle is machined from surgical-grade stainless steel, allowing free axial rotation between two fingers during multi-directional scooping strokes. Overall instrument length is 165 mm (6.5 inches), balancing consistently at mid-handle throughout clinical use.

The 4.0 mm blade width positions this spoon curette within the larger end of the Lucas series, covering standard third molar and wide molar alveoli where smaller spoons fail to maintain full wall contact. The spoon rim carries no lateral cutting edge — the working motion is a controlled inward scrape rather than a slice. The stainless steel body tolerates autoclave sterilization at 134°C without blade deformation or handle oxidation across repeated cycles. The hollow handle core reduces dead weight while keeping shank stiffness intact during active strokes.

Oral surgeons and general dentists use the 90 Lucas Spoon Shape Curettes after large posterior tooth and third molar extractions to debride granulation tissue, periapical cyst linings, and necrotic bone fragments from the alveolus. Surgeons work each socket wall quadrant with short inward scooping strokes, clearing all debris systematically before placing a bone graft or closing the flap with primary sutures.

The instruments that come out of Leader Surgical carry a consistency that surgical teams notice immediately — from the weight distribution in hand to the edge retention after multiple sterilization cycles, nothing feels like an afterthought.

Is the “90” model different from other Lucas curettes?
The “90” refers to the specific size or variant. Lucas curettes typically range from smaller sizes like #84 (2.0mm–2.4mm) to larger sizes like #88 (4.7mm). The specific dimensions of a “90” variant may vary by manufacturer but follow the same double-ended, angled spoon design.
