Why dentists choose ErgoDenta for Periodontal Knives
Periodontal knives are purpose-built for sculpting gingival tissue. Our range covers the two designs every perio surgeon relies on — Kirkland knives for external gingivectomy and bevelling, and Orban knives for clean interproximal access on both mesial and distal surfaces.
Blades are machined from high-carbon stainless steel, hand-sharpened to a surgical edge, and paired with slim perio-surgery handles for precise control in tight spaces.
Frequently asked about Periodontics
Which Gracey curette goes in which sextant?
1-2 anterior, 3-4 anterior, 5-6 anterior/premolar, 7-8 posterior buccal/lingual, 9-10 posterior buccal/lingual, 11-12 posterior mesial, 13-14 posterior distal, 15-16 posterior modified mesial, 17-18 posterior modified distal.
Standard, Rigid, Mini or Titanium — what is the difference?
Standard for routine scaling, Rigid for heavier calculus removal, Mini for tight pockets and furcations, Titanium specifically for implant maintenance (will not scratch the implant surface).
How often should curettes be sharpened or replaced?
Sharpen after every 10-15 patients with a fine ceramic stone. Replace once the working edge falls below 50% of original — usually 12-18 months in steady use. Our ErgoRazor® line holds an edge longer.
Are universal curettes a substitute for Graceys?
No — universal curettes (Columbia 13/14, Younger-Good 7/8) work in all sextants but at the cost of site-specific blade angulation. Graceys give better access at the expense of needing more pieces in the cassette.
