Bone curettes are the quiet workhorses of oral surgery. Used after extraction to clean granulation tissue, after apicoectomy to remove cyst lining, after socket preservation to enucleate. Get the pattern wrong and you're fighting the bone instead of working with it.
This guide explains the three dominant patterns (Lucas, Molt, Volkmann), the size convention (85, 86, 87, 88), and which combination covers a typical surgical practice.
TL;DR
Lucas curettes = spoon-shaped, oval working end. The standard for granulation tissue removal. Sizes 85–88 = increasing tip diameter (2.5mm → 4mm). Molt curettes = sharper edges, double-ended (anterior + posterior), used for cyst enucleation. Volkmann = sharper, longer, used in orthopaedic and complex surgical work.
Lucas curette sizes
| Size | Tip diameter | Length | Best for | Cross-arch use |
|---|---|---|---|---|
| Lucas 85 | 2.5mm | 17cm | Anterior socket curettage, tight access | Anterior teeth |
| Lucas 86 | 3.0mm | 17cm | Premolar socket curettage | Premolars |
| Lucas 87 | 3.5mm | 17cm | Molar socket curettage (most-used) | Molars (general) |
| Lucas 88 | 4.0mm | 18cm | Large molar sockets, cysts | Posterior molars, surgical sites |
Lucas vs. Molt vs. Volkmann
| Pattern | Shape | Edge | Length | Best use |
|---|---|---|---|---|
| Lucas | Oval spoon, round-edge | Smooth or serrated | 17–18cm | Granulation tissue removal post-extraction |
| Molt (Nordberg-Molt) | Double-ended (anterior + posterior) | Sharper than Lucas | 18cm | Cyst enucleation, periapical lesions |
| Volkmann | Long-handle, larger spoon | Very sharp | 18–22cm | Orthopaedic / complex surgical bone work |
| Periosteal Elevator (Molt 9) | Flat blade | Sharp, beveled | 15cm | Mucoperiosteal flap reflection |

How to build a complete surgical bone curette set
- Lucas 86 + 87 — covers most general extraction sites
- Lucas 88 — for larger sockets and cyst sites
- Molt 4mm-7mm double-ended — for cyst lining enucleation and periapical work
- Periosteal elevator (Molt 9) — for flap reflection
- Mini bone curette (Lucas 85) — for tight anterior access
Serrated vs. smooth edges
Lucas curettes come in two finishes: smooth and serrated. Smooth is the original — gentler on bone, less aggressive on granulation tissue, more predictable cuts. Serrated grips granulation tissue better and cuts faster, but is more aggressive on healthy bone — risk of removing more than intended.
Most surgeons keep one of each: serrated for the bulk debridement, smooth for the final pass.
Why surgical curettes need premium steel
Bone work dulls instruments fast. A standard stainless curette loses its edge after 50–80 uses on cortical bone. Our ErgoRazor® surgical line uses harder cobalt-chromium steel that holds the edge 2–3× longer — important when a single dull curette can extend a surgery by 5 minutes.
