Fine-tuning in detail: optimill acero nf for more process reliability in everyday milling work
When CAD/CAM milling metals, it is not just the alloy that is decisive, but the interaction between material, machine and workflow. This is precisely where dentona comes in with the new CAD/CAM disc optimill acero nf. The tried-and-tested CoCr milling blank has been further developed with the aim of further improving process reliability, cost-effectiveness and reproducible results in everyday laboratory work.
optimill acero nf is a CoCr disc that combines machining convenience, process reliability and cost-effectiveness – for a stable, predictable milling routine in the dental laboratory.
Proven basis, specifically readjusted
optimill acero nf builds on the established CoCr basis of the predecessor material. Fine-tuning is crucial: purity, homogeneity and microstructure have been optimised. The result is a material that is particularly stable and predictable in everyday laboratory work; an advantage especially for laboratories with high throughput and clearly defined process chains.
Efficient machining, reduced tool wear
The optimised microstructure ensures convenient machining and supports uniform cutting. At the same time, it helps to reduce tool wear and increase edge stability. For the laboratory, this means more planning reliability, consistent quality and more economical use of tools.

Biocompatible, corrosion-resistant, ceramic-compatible
As a tungsten-free, nickel-free and beryllium-free CoCr disc, optimill acero nf fulfils high requirements for biocompatibility and corrosion resistance. The alloy is matched in such a way that the coefficient of thermal expansion (CTE) is compatible with common veneering ceramics – a solid basis for a reliable metal-ceramic bond. Polishability was also specifically taken into account in order to keep the finishing process in the laboratory efficient.
Open system and reliable process integration
Thanks to standardised, reproducible process chains, optimill acero nf is compatible with CAD/CAM milling machines designed for this purpose across all systems. This means that the material can be easily integrated into existing workflows – regardless of the milling technology used.
With optimill acero nf, dentona once again demonstrates that CAD/CAM materials are not viewed in isolation. Further developments are based on the principle of considering material, processing and workflow as a unit.
