Implantable medical devices are one of the most demanding areas for materials: medical devices must be biocompatible but also resistant to wear, to sometimes extreme mechanical stresses, aging in a biological environment over long periods of time while ensuring a reliability close to 100%.
For these reasons, ceramics is widely used in the design and manufacturing of medical devices. Today, in order to respond to the increasing life expectancy of patients and increasingly demanding regulations, ceramics used for the production of medical parts must be increasingly efficient and reliable.
Nanometric powders: providing a reliable product for the medical field
Nanoe offers a wide range of powders specially designed for medical devices. We offer alumina and zirconia, but especially ZTA, which is composed of both zirconia and alumina, this enables it to inherit the benefits of both materials. These powders are resistant to wear, bending, shock and hydrothermal ageing.
The powders proposed by Nanoe comply with applicable regulations and standards, in particular ISO-6474-1 for alumina and ISO-6474-2 for the ZTA.
Titanium is a material very much used for making dental implants as it is light and displays good osteo-integration. However, so that the integration into the bone works best, titanium implants need to achieve a specific roughness via sandblasting. Nanoe therefore, offers high purity, black TiO2 abrasive powder for post-treatment of these implants without risk of pollution.
Titanium can sometimes be the source of severe allergies in some patients. It is more subject to electrochemical corrosion, particularly in the oral environment that can be acidic. Ceramic is therefore an excellent alternative as it is resistant to moisture and acidity. For this application, Nanoe offers zirconia and Alumina Toughened Zirconia (ATZ) powders that have very good mechanical properties while remaining very aesthetic.
Nanoe offers a ZTA composed of 25% zirconia and 75% alumina for the production of hip prostheses. In addition to meeting regulatory requirements, the ZTA 25 proposed by Nanoe allows for more complex designs with thinner shapes than conventional alumina. The prostheses are smaller and lighter, improving patient comfort.
Nanoe also offers a pink ZTA doped with chrome and strontium for even stronger ceramics.
