89 Lucas Spoon Shape Curettes

The 89 Lucas Spoon Shape Curettes is a double-ended instrument with mirror-image spoon blades, each measuring 3.0 mm in width as confirmed by the LS1-298 article reference and visible tip dimension in the product image. Both working ends sit on terminal shanks angled at 50 degrees with a 21 mm reach, directing the concave spoon face against socket walls without handle obstruction on neighboring teeth. The round hollow handle is machined from surgical-grade stainless steel, reducing overall instrument weight while maintaining shank rigidity during active strokes. Overall instrument length is 165 mm (6.5 inches), with the balance point centered at mid-handle for controlled scooping pressure.

The hollow handle construction on the Lucas Spoon design reduces wrist fatigue during extended curettage sessions compared to solid-body variants. The spoon rim carries no lateral cutting edge — the working motion is an inward scooping scrape directed along the socket wall surface. The stainless steel alloy resists corrosion through repeated autoclave sterilization at 134°C without surface oxidation or blade deformation across clinical use cycles.

Oral surgeons and general dentists use the 89 Lucas Spoon Shape Curettes after standard molar and premolar extractions to remove granulation tissue, necrotic bone fragments, and periapical cyst remnants from the alveolus. The Dental Periodontal Lucas Spoon Shape Curette class covers socket diameters from 2.2 mm to 4.7 mm across the full Lucas series, with the #89 targeting medium molar socket diameters. Surgeons work each socket wall quadrant with short inward strokes before graft placement or wound closure.

Leader Surgical doesn’t rely on reputation alone — each instrument leaving the production line meets the same dimensional and material standard that surgical teams have come to depend on.

What is the standard length?
While it varies by manufacturer, many models have an overall length of approximately 6.5 inches (16.5 cm) to 7 inches (18 cm).
