Economic advantages for your laboratory

The key question: Is Mediloy® M-Co economically viable for my laboratory?

Find out for yourself by calculating your previous costs per milled unit, including tool wear, and comparing them to Mediloy® M-Co.

When using Mediloy® M-Co, after a while you will discover that your costs for tools and their wear are decreasing significantly, thanks to the excellent milling properties of the material.

In addition to these outstanding, approved properties you also benefit from the reliable compatibility of BEGO partial denture alloys, Wirobond® C+ SLM frameworks (e.g., primary crowns) and units milled from Mediloy® M-Co (e.g., crowns/secondary crowns).
