NEW MATERIALS FOR ACTIVE AND HEALTHY AGEING

CHALLENGES ADDRESSED

Human life is increasing more and more and it is becoming common the need for the implantation of prosthesis in youth people due to injuries caused by the active lifestyle. However, the reduced life-time of current prosthesis frequently oblige to the replacement of such prosthesis. Therefore new nanomaterials with higher strength and better biological and mechanical behavior with a lifetime similar to the patients’ one are required.

Dental implants are also an important challenge for research on nanomaterials looking for optimal biological, aesthetical and mechanical properties. 

Another critical issue is the increasing bacterial resistance to antibiotics and an intensive research is performed worldwide in order to obtain biocidal materials featuring a strong antibacterial activity against a broad number of pathogens and a reduced toxic effect on both human health and environment.

OUR EXPERTISE
Dental implantology

CINN research is focused on ceramic solutions for crowns, abutments, and implants mainly based on zirconia and alumina/zirconia composites.

One of the most prominent results in this field has been the development of a simple and inexpensive process for controlling final colour of the zirconia materials. Thanks to this process it is possible to imitate the natural teeth of the patient while preserving the high mechanical properties and ageing behavior of white zirconia materials.

Hip and knee prosthesis

CINN research on ceramic nanocomposites for hip and knee prostheses started in 2001 within the frame of the European Project Bioker.

Due to the biocompatibility and good mechanical properties of both aluminum oxide and zirconium oxide the main research interest of the CINN in this field is the development of alumina-toughned-zirconia (ATZ) and zirconia-toughned-alumina (ZTA) materials in the micro-nano and nano-nano systems.

The intelectual property from the research performed comprises two patents on alumina-zirconia nanocomposites with featured enhanced reliability over currently known oxidic ceramic materials thus providing a lifetime close to patient's life expectancy.

Biocides

In order to overcome the limitations of current organic biocides the CINN has directed its research towards inorganic materials and particularly to two kind of materials:

• environmentally-friendly glasses, the so-called eco-biocides and,

• biocides based on metal nanoparticles supported on silicates and calcium phosphates.

One of our current interests is the functionalization of ceramic implants and prosthesis in order to avoid surgical infections. However these materials are very promising in other many applications such as water treatment, agriculture, food preservation, prevention of bio-fouling and corrosion....
