Description
Dental burs for crown removal
Features
-
Unique dental bur designed for cutting porcelain-fused-to-metal (PFM) crowns and full-metal crowns.
-
Cuts efficiently through ceramic veneering and the underlying metal structure without instrument changes.
-
Available in different working lengths: 2.0 mm, 3.5 mm, 5.0 mm, and 8.0 mm.
-
Tip with a transversing blade on tungsten carbide burs for easier penetration into crown material.
Benefits
-
Time-saving solution: no need to switch instruments when cutting metal-ceramic crowns.
-
Reduced heat generation thanks to optimised chip evacuation.
-
Pyramidal cutting geometry ensures precise and effective crown sectioning.
-
Durability and long service life, even under demanding clinical use.
Recommendations for Use
-
Optimal rotation speed: 160,000 rpm with a micromotor.
-
Work at a 45° angle between the bur and the crown to be removed.
-
Always use sufficient irrigation (minimum 50 ml/min).
-
Do not exceed a working pressure of 2N.
-
For non-precious alloys prone to chipping, use with a turbine applying light pressure.
-
For zirconia and high-fusing ceramics, use 4ZR/4ZRS burs instead of the H4MCXL.
- Assigned Material: no full ceramic
- Maximum Speed: 450000
