Why Choose a Diamond Bur for Zirconia Fine Grit Work?

Working with zirconia demands instruments engineered to match the material's exceptional hardness. A dedicated diamond bur for zirconia fine grit application ensures smooth surface preparation without inducing micro-cracks or structural stress in the restoration. The Ziramant special diamond coating is formulated to maintain cutting efficiency throughout the working cycle, reducing the need for frequent instrument changes and supporting consistent clinical outcomes.

Instrument Dimensions

Per ISO 6360, the size number is the maximum head diameter in tenths of a millimeter. See our Busch Bur Size Chart for the full size conversion table, shank codes, and color ring guide.

Applications

This diamond bur for zirconia fine grit preparation is particularly suited for crown and bridge workflows where precision marginal adaptation and smooth surface finishing are critical to long-term restoration success. The egg-shaped geometry facilitates access to contoured surfaces and internal preparation zones commonly encountered in full-contour zirconia restorations.

The diamond bur for zirconia fine grit is well-suited for the following dental laboratory applications:

	Crown and Bridge Technology — Shaping, trimming and finishing of crown and bridge frameworks in the laboratory.
	Processing of Zirconium Oxide — Cutting, contouring and finishing of zirconium oxide restorations.
