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.
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.
Titanium is a very used material for making dental implants because it is very light and has a good osteo-integration. However, this material can cause severe allergies with certain patients. It is subject to electrochemical corrosion, especially in the oral environment that can be quite acidic. Ceramic is an excellent alternative. It is resistant to moisture and acidity. Nanoe proposes for this application zirconia and ATZ powders having both very good mechanical properties while remaining aesthetic.
