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.
Advantages :
Exceptional durability: The cobalt-chromium frame is extremely resistant to corrosion and wear, ensuring a long service life for the prosthesis.High performance: Efficiently withstands masticatory forces, offering a reliable and stable solution for dental restorations.
Customizable aesthetics: Provides a superior aesthetic finish with various customization options to meet the specific needs of each patient.
Disadvantages :
Regulatory and health considerations: The use of cobalt chromium must be carefully considered due to regulatory restrictions and health concerns related to its classification as a CMR substance.
Despite regulatory concerns, the rigid ackers on Chrome Cobalt chassis offer a variety of customization options for precise and comfortable adaptation to each clinical case. These options include customization of tooth and gum shape and color, ensuring optimal functionality and natural aesthetics.
Custom-machined teeth in multilayer PMMA offer natural aesthetics and optimal functionality, faithfully reproducing the appearance and texture of natural teeth.
Acrylic resin gingiva is designed with attention to detail to provide a realistic appearance and harmonious integration with the patient's natural gingiva.
