11 1/2
22mm
When canal diameter continues to increase, a correspondingly larger tip becomes advantageous. The NES-1490 adopts the 11½ pattern at 22 mm, providing additional surface area for condensation while still benefiting from the control of a moderate working length. The tip geometry spreads thermal energy or packing force across a wider cross-section of the obturation material, reducing voids and improving homogeneity of the fill.
High-grade stainless steel preserves the instrument’s form through multiple sterilization and heating cycles. The 22 mm length strikes a practical balance—long enough for reliable apical access in most cases, yet short enough to keep the operator’s hand stable and responsive. Single-ended construction further lightens the instrument and simplifies orientation inside the access cavity. Handle diameter selections accommodate individual preferences and help maintain consistent pressure throughout the packing sequence.
This pattern is frequently selected in the later stages of obturation for wider canals. It functions as a specialized diagnostic instrument companion from Next Edge Surgical LLC—assisting in the evaluation of canal preparation while enabling thorough, efficient material adaptation. Durable and purpose-built for larger anatomy.
