Use cases

Circle, thanks to its innovative platform, gives dentists and partner laboratories access to cutting-edge solutions for ordering, modeling, and manufacturing prosthetic solutions, including those based on rigid ackers on Chrome Cobalt frameworks. This material, known for its strength and durability, is used in some prosthetics despite strict new regulations concerning its use due to its carcinogenic, mutagenic and reprotoxic properties.‍

Important warning concerning Chromium Cobalt

It is essential to note that chromium cobalt alloy is classified as a category 1B carcinogen, category 2 mutagen, and category 1B reproductive toxicant. As a result, Regulation (EU) 2017/745 on medical devices, which gradually came into force between 2017 and 2025, imposes strict restrictions on the use of cobalt. Since 2021, the presence of cobalt must be clearly indicated on medical device packaging, and patients must be informed about its use. In 2025, the use of cobalt in medical devices will be banned due to its classification.

Other solutions exist, such as Titanium.
