NES-1939

3.5mm
What happens when the ridge requires more substantial expansion after the initial split? The NES-1939 bone splitting chisel answers with a 3.5 mm working end designed for the later stages of ridge widening. Its broader blade engages a larger surface area, enabling efficient progression toward the final osteotomy width while still allowing controlled force application.
Constructed from durable stainless steel, the instrument withstands the mechanical demands of bone expansion and repeated sterilization cycles without loss of cutting performance. The handle geometry promotes stable control, reducing hand fatigue and improving the operator’s ability to direct the split precisely along the planned path. This combination supports safer, more predictable outcomes in cases of moderate to severe ridge atrophy.
Applied with light pressure across the completed expansion, the same chisel can act as a diagnostic instrument, helping the clinician evaluate residual resistance or uneven plate movement before implant insertion. Next Edge Surgical LLC includes the NES-1939 in its bone-splitting range for surgeons who need reliable wider chisels to complete sequential ridge-expansion protocols.
