Description
Arum® Cortical Drill – Engineered for Crestal Precision, Built for Stability
Included in NB Master & Regular Kits | Available at Summit Dental Supply
The Arum Cortical Drill is purpose-built to selectively widen the crestal cortical bone, reducing insertion torque and enabling smoother seating of NB (I) & (II) implants. Especially effective in dense bone or posterior zones, this precision drill minimizes crestal compression and helps preserve bone integrity—critical for primary stability and long-term implant success.
