NES-1819

Fig. 5
Do you know when does a surgeon reach for the largest curvature in a sinus lift set? Once the membrane is already partially elevated and the goal shifts from careful initial separation to completing a wider lift across the sinus floor. That’s the role the NES-1819, Fig. 5 in the sequence, is built to play.
Its broader, curved working end covers more surface area per pass than the smaller figures in the set, which matters when the surgical plan calls for enough elevated space to accommodate bone graft material or a longer implant fixture. The tip stays non-perforating by design, rounded to glide beneath the membrane rather than risk puncturing it during these final stages of the lift.
A few specifics worth knowing:
Largest curvature in the graduated sinus lift sequence, used after initial elevation is established
Blue plasma coating resists corrosion and reduces friction against bone during extended procedures
Rounded, blunt tip minimizes perforation risk even under the added pressure of a wider lift
Functions as a practical diagnostic instrument for confirming even membrane elevation before graft placement
Offered with hollow handle Ø 8mm, Ø 9.5mm, or solid handle Ø 6mm
Built from surgical stainless steel and autoclave-rated for repeated use, the NES-1819 rounds out a complete sinus lift set for oral surgeons and implantologists handling lateral window or crestal approach procedures.
