Crown Cutting Burs

Description

Crown cutting burs are heavy duty rotary instruments engineered to section and remove existing crowns and bridges quickly and safely. Used with a high speed handpiece and copious water spray, they create access grooves, split retainers, and cut through metal frameworks so the restoration can be lifted off without damaging the underlying tooth. The working heads are precision cut for aggressive yet controlled removal, while the rigid shank keeps the bur steady at depth.

Key features and benefits:

• Tungsten carbide or diamond options to match the material you are cutting.

• Cross cut geometry bites efficiently into metal and PFM frameworks, reducing skating.

• Diamond crown cutters open porcelain and ceramic layers with smoother control.

• Long, rigid shank improves reach and visibility during sectioning.

• Balanced manufacture limits vibration for patient comfort and better accuracy.

• Autoclavable for reliable chairside infection control.

• Typically available in common shapes such as tapered fissure, round end taper, and cylinder for different cut paths.

Typical uses and applications:

• Sectioning full coverage crowns and multi unit bridges prior to removal.

• Cutting retention grooves to disengage cemented restorations.

• Reducing metal collars and adjusting occlusal anatomy on temporary refits.

• Dividing PFM into porcelain and metal layers for controlled removal.

How it compares:

• Versus standard diamond finishing burs, dedicated crown cutters remove material far faster and last longer under high load.

• Versus elevators alone, creating a precise section line lowers risk of tooth or root fracture and shortens appointment time.

Clinical guidance:

• Use steady, light pressure and continuous water spray to control heat and debris.

• For zirconia and other high strength ceramics, choose diamond crown cutting burs rather than metal cutting carbides.

• Replace worn burs promptly to maintain cutting efficiency and protect tooth structure.
