GZH257-6c Pre-Sintered Zirconia Polishing Bur | Coarse Large Tapered Cone

GZH257-6c Pre-Sintered Zirconia Polishing Bur

The GZH257-6c is a pre-sintered zirconia polishing bur designed for dental laboratory adjustment of green-state zirconia before final sintering. Its Coarse abrasive profile helps technicians refine contours, smooth surfaces, and prepare restorations with controlled cutting performance.

Key Features

• Designed for pre-sintered zirconia and green-state zirconia restorations.
• Coarse abrasive option for efficient finishing and controlled material removal.
• Large tapered cone profile for model-specific access and contour adjustment.
• Suitable for dental lab workflows before final zirconia sintering.

Applications

• Pre-sintered zirconia crown and bridge adjustment.
• Surface smoothing, contour refinement, and margin area finishing before sintering.
• Dental laboratory zirconia polishing and finishing procedures.
