NES-1812

Ø 4 mm
The NES-1812 is the largest cup size in the Lucas curette lineup at Ø 4mm, built for the jobs that need coverage more than precision — clearing out larger extraction sockets, cystic cavities, and areas of granulation tissue that would take several passes with a smaller instrument.
What the larger cup adds to the workflow:
Covers more surface area per stroke, cutting down debridement time in bigger surgical sites
Well suited to molar extraction sockets and multi-rooted cavities where a small cup would need repeated passes
Sharp, curved rim lifts soft tissue and debris cleanly without dragging across bone
Works alongside smaller Lucas curettes as the “first pass” instrument before finer cups finish the detail work
Hollow handle at Ø 8mm keeps overall weight manageable despite the larger cup
Cyst enucleation and apicoectomy procedures often call for this size specifically, since the goal is thorough removal of the cyst lining or periapical tissue rather than delicate, spot-by-spot cleanup. The cup’s edge also gives clinicians a reliable diagnostic instrument for sweeping a cavity and confirming no residual tissue remains before the site is closed or grafted.
Machined from surgical stainless steel and rated for standard autoclave sterilization, the NES-1812 holds its edge through repeated surgical use without deforming. A dependable choice for oral surgeons managing larger post-extraction or periapical surgical sites where efficiency matters as much as precision.
