Ochsenbein bone chisel #3

The Ochsenbein Bone Chisel #3 (Article# LS1-377) is a double-ended periodontal chisel measuring 165 mm (6.5 inches) overall, with mirror-image curved blades on each end carrying semi-circular notches beveled on both sides of the blade margin. The 4 mm bi-beveled working tip features a rectangular cross-section with sharp lateral cutting edges, oriented to engage interproximal bone from the facial approach without contacting adjacent root surfaces. The round ringed knurled handle is machined from surgical-grade stainless steel, providing stable three-finger control during both push strokes and lateral scraping action throughout active surgical use.

The double-ended configuration distinguishes the #3 from the single-ended #1 and #2 variants — placing two working approaches on one instrument and reducing tray count during osseous surgery. The bilateral bevel on each Ochsenbein notch allows the blade to cut on both the push and pull stroke, unlike single-bevel chisels that are limited to one directional motion. The rectangular blade cross-section generates a shearing force against bone margins during lateral strokes, making it effective for heavy supragingival calculus removal from open interproximal surfaces. The stainless-steel body tolerates autoclave sterilization at 134°C without edge degradation across clinical use cycles.

Periodontists use the Ochsenbein Bone Chisel #3 during osseous resective surgery, osteoplasty, and crown lengthening procedures requiring interproximal bone recontouring. The Ochsenbein Periodontal Chisel #3 also reflects periosteal flaps, removes secondary palatal flaps, and dislodges remaining fiber attachments from root surfaces after tooth extraction. Surgeons activate the blade with horizontal push strokes directed facial to lingual along open embrasure spaces.

Leader Surgical backs every instrument it produces with the same manufacturing discipline — consistent blade geometry, verified material composition, and dimensional accuracy that clinicians can count on tray after tray.

What is the “Ochsenbein #3” specifically known for?
The #3 model is often slightly narrower than the #1 and #2, making it the “go-to” for narrow interproximal spaces where a standard chisel might be too bulky to fit between the teeth.
