ELA Inverted Cone Tungsten Carbide Burs (C25 Series, ISO Shape 245) are precision-engineered rotary instruments specifically designed for traditional amalgam and composite cavity preparations, establishing flat pulpal floors, and cutting sharp internal line angles. Characterized by a slightly elongated inverted cone geometry (ISO Shape 245), these burs provide superior control when defining retention locks and squaring internal walls compared to standard short inverted cones.
Key Clinical Applications:
Classic Cavity Preparations: Ideal for opening and defining Class I and Class II cavity outlines with well-defined, flat floors.
Retention & Undercut Formation: Creates precise mechanical undercuts and sharp internal line angles for optimal restorative retention.
Restorative Removal: Effectively slices through old filling materials and contours bulk tooth structure.
Product Features:
ISO Shape 245 Elongated Geometry: Slightly longer head profile ensures exceptional stability and clean lateral cutting action.
Micro-Grain Tungsten Carbide: High-density carbide composition maximizes blade edge retention, structural durability, and resistance to wear.
Dual Shank Options (FG & RA): Available in Friction Grip (FG) for high-speed handpieces or Latch-Type (RA) for slow-speed contra-angles.
Convenient Pack of 2: Clinical blister packaging ensuring sterile-ready, dependable performance for daily procedures.
