NES-1818

Fig. 4
The NES-1818, Fig. 4 in the sinus lift series, picks up where the smaller curvatures leave off — built for the middle stage of membrane elevation once the initial separation has created enough space to work with a slightly broader tip.
What this size brings to a sinus augmentation procedure:
Curved, non-perforating tip shaped to advance along the sinus floor without catching or tearing membrane tissue
Blue plasma coating for reduced drag against bone and easy visual identification within a graduated instrument set
Works as a bridge between the finer initial-access instruments and the wider elevators used for full lift completion
Doubles as a functional diagnostic instrument for feeling out membrane resistance and confirming safe progression before advancing further
Available in hollow handle Ø 8mm, Ø 9.5mm, or solid handle Ø 6mm to match surgeon preference
Sinus lifts rarely succeed with a single instrument size — the procedure calls for a graduated approach where each figure number takes over once the previous one has done its part, gradually widening the elevated space without applying excessive force at any single point. The NES-1818 fills that mid-sequence role reliably.
Machined from surgical stainless steel and rated for standard autoclave sterilization, it holds its coating and edge integrity through repeated implant and grafting procedures. A dependable middle piece for any complete sinus lift set.
