The Kramer-Nevins 1 and 2 Periodontal Chisels are a paired set of surgical instruments used in periodontal osseous surgery. The #1 chisel typically has a straight blade for general bone planing and ledge removal, while the #2 chisel features an angled blade for accessing interproximal areas and line angles. Both are used with a mallet to perform osteoplasty (reshaping bone) and osteoectomy (removing bone) to eliminate bony defects and create positive architecture that facilitates soft tissue adaptation and pocket elimination. They are essential tools for executing controlled, manual bone recontouring during periodontal flap procedures.
Unique Value Proposition: This set provides the two fundamental blade designs needed for comprehensive bone contouring. It solves the problem of having an incomplete toolkit by offering both a straight chisel for broad surfaces and an angled chisel for tight spaces, enabling the surgeon to address a wide variety of osseous defects predictably and effectively.
