Overview

ELA Pear & Conical Tungsten Carbide Burs (C7L Series, ISO Shape 330) are precision rotary instruments engineered for conservative cavity preparations, smooth internal line angle rounding, and efficient access opening. Manufactured from premium micro-grain tungsten carbide, the C7L pear-shaped geometry (Size 008) transitions smoothly from a rounded tip to divergent walls, making it the gold standard for opening small pits, fissures, and shallow carious lesions while naturally reducing internal stress concentrations.
Key Clinical Applications:
Conservative Cavity Preparations: Ideal for Class I and Class II cavity designs, creating smooth, rounded internal angles that prevent restorative material fracture.
Access Openings: Effectively penetrates enamel and dentin to outline small restoration margins and conservative access paths.
Caries Removal & Shaping: The pear profile allows simultaneous cutting of flat pulpal floors and curved lateral walls.
Product Features:
Classic ISO 330 Pear Geometry: Delivers optimal contours for conservative cavity designs and stress-relieved internal angles.
Micro-Grain Tungsten Carbide: High-density carbide composition ensures exceptional blade edge retention, structural rigidity, 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.
Value Pack of 2: Convenient clinical blister packaging ensuring sterile-ready, dependable performance.
