Gingival Curettage Burs - FG Torpedo Diamond Burs
Eagle gingival curettage burs are FG diamond burs with a torpedo (round-nosed chamfer) head, made for rotary gingival curettage during crown preparation. The range includes 11 shapes - S1 to S5 and T1 to T6 - in tapered, cylindrical and long torpedo profiles, with grits from super fine to super coarse.
Rotary curettage, also called gingitage, is a troughing technique for subgingival margins: as the torpedo diamond extends the finish line into the sulcus and forms a chamfer, it also removes the sulcular epithelium. The result is an exposed, clearly defined margin for the impression and the final restoration.
Clinical Uses
- Rotary gingival curettage (gingitage) - extending the finish line subgingivally while removing the sulcular lining
- Chamfer margins - forming and refining chamfer finish lines in crown and bridge preparation
- Subgingival margin preparation - Class II and Class V preparations that extend below the gingival margin
- Impression troughing - creating a clean, visible margin for conventional or digital impressions
Rotary curettage is typically indicated for healthy gingiva: no bleeding on probing, a shallow sulcus and adequate keratinized tissue. Use generous water spray throughout.
Rotary Gingival Curettage: Step by Step
A general outline of the technique - follow your own clinical protocol and training.
- Assess the tissue: confirm healthy gingiva and sulcus depth before planning a subgingival margin.
- Prepare to the gingival margin: complete axial reduction and place the chamfer at the gingival level first.
- Choose the torpedo: match the head diameter to the chamfer width you planned (S codes smaller, T codes larger).
- Extend into the sulcus: with water spray and light pressure, carry the torpedo tip slightly below the gingival margin, following the tooth contour so the chamfer and the curettage happen in one pass.
- Refine: smooth the finish line with a fine or super fine torpedo of the same shape.
- Control bleeding and record: manage any bleeding per your protocol before taking the impression or scan.
Grit Guide
- Black band - Super Coarse: rapid reduction
- Green band - Coarse: chamfer preparation and rotary curettage
- No band - Medium: general preparation and margin extension
- Red band - Fine: refining the chamfer and finish line
- Yellow band - Super Fine: final smoothing of the margin
Not every shape comes in every grit - choose the code first, and the selector shows the grits available for it.
Shapes and Codes
Each code is listed with its equivalent ISO shape and size reference (shape number - head diameter in tenths of a millimeter). S codes have smaller heads (1.4-1.6 mm); T codes have larger heads (1.6-2.2 mm).
- Tapered torpedo (878K): S2 (014), S5 (016), T3 (018), T1 (020), T2 (022)
- Cylindrical torpedo (877K): S4 (014), T5 (016), T4 (018)
- Long torpedo (879K): S3 (014), S1 (016), T6 (018)
See the size chart in the product images for the head shape of each code.
Choosing a Torpedo Shape
- Tapered torpedo: the usual choice for full-coverage crown preps, matching a tapered axial wall
- Cylindrical torpedo: parallel walls and a uniform chamfer depth
- Long torpedo: long clinical crowns and extended axial walls
Chamfer Bur vs Flame Bur
A torpedo chamfer bur has a rounded tip, so it leaves a defined chamfer that is easy to read on an impression or scan. A flame bur tapers to a point and leaves a feather-edge finish line. Choose the chamfer bur when the design calls for a clear margin with room for the restorative material.
How to Get the Most From Each Bur
- Run the FG bur in a high-speed handpiece at the speed recommended by the handpiece and bur manufacturer.
- Always use water spray; dry cutting overheats the tooth and the tissue.
- Use light pressure and keep the bur moving.
- Replace a bur when it stops cutting efficiently - forcing a dull bur raises heat and tissue trauma.
Cleaning and Sterilization
These burs are autoclavable and reusable. Before each use, pre-soak in a bur-compatible disinfectant, brush or clean ultrasonically in a bur holder, rinse, dry, pouch and autoclave following your clinic's reprocessing protocol. Inspect each bur and discard it if the diamond coating is worn or the shank is bent.
