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 H4MC.
