NES-1908

Fig. 86S
Narrower blade suited to confined proximal boxes
Single-bevel edge for precise enamel cleavage
Straight shank that maintains directional control
Access remains the limiting factor in many posterior preparations. The NES-1908 Fig. 86S addresses that limitation with a more slender working end that enters restricted spaces while still delivering a clean cutting action. Operators use it to plane axial walls, refine gingival seats, and remove residual enamel tags that rotary instruments leave behind. The reduced bulk improves visibility and lowers the risk of adjacent-tooth contact during instrumentation.
Stainless-steel construction ensures the cutting edge stays serviceable through multiple sterilization cycles. The handle diameter and surface texture promote a secure yet relaxed hold, allowing measured force application even when the working field is wet or poorly lit. This reliability shortens the hand-instrument phase of cavity preparation and supports consistent internal form.
In the final check before filling, the Fig. 86S pattern can serve as a diagnostic instrument by lightly tracing the preparation margins to confirm smoothness and completeness of enamel removal. Next Edge Surgical LLC offers this model to practices that require finer chisel options for detailed restorative work.
