3 Fedi Periodontal Chisel

The 3 Fedi Periodontal Chisel is a double-ended instrument constructed from surgical-grade stainless steel, offering strong corrosion resistance through repeated autoclave cycles. The working end measures 2.8mm in width, set at a 40-degree angle, allowing the blade to reach interproximal spaces without obstruction. Both ends carry slightly curved, thin blades with semi-circular cutting edges that hold sharpness across multiple uses. The handle features a knurled, round-barrel body providing a firm, non-slip grip during active surgical manipulation. The instrument is balanced symmetrically around the central handle for controlled, two-handed use.

The instrument body is machined from a single piece of stainless steel, eliminating joint weak points and supporting long-term structural integrity. The Fedi periodontal chisel series differs from standard bone chisels through its blade geometry — the slight curvature and narrow width target soft tissue incision rather than bulk bone removal. The green-tinted surface coating, visible on the handle, reduces glare under operative lighting without affecting sterilization compatibility. The instrument is fully autoclavable and reusable, meeting standard surgical instrument care protocols.

Periodontists use the 3 Fedi Periodontal Chisel during open-flap debridement and resective osseous surgery. The surgeon uses the curved blade to make secondary sulcular incisions along the root surface, severing residual periodontal fibers after the primary flap incision. It also excises interproximal soft tissue tabs between adjacent teeth during flap reflection. In osseous recontouring, it accesses narrow embrasure spaces where wider instruments cannot reach.

The CHISEL FEDI N.3 suits surgeons who require consistent blade geometry across a demanding clinical caseload. Leader Surgical stands behind this instrument with strict dimensional tolerances, material consistency, and sterilization-safe finishing — making it a dependable addition to any periodontal surgical kit.

What is the primary function of the 3 Fedi Chisel?
It is specifically designed for making secondary sulcular incisions during flap surgery and for the removal or recontouring of soft tissue.
