New coating improves<br />
medical product and<br />
dental procedures<br />
The <strong>Danish</strong> <strong>Technological</strong><br />
<strong>Institute</strong> has developed a new<br />
carbon-based low friction coating<br />
to be used on screws for dental<br />
applications. The product works<br />
better than former surface-treated<br />
titan implants and is easier for<br />
dentists to work with.<br />
The new product allows the dentist<br />
to run the screw more smoothly<br />
during procedures like implanting a<br />
crown in a patient’s jawbone. The<br />
customised dental implant coating<br />
is designed not only to be smooth<br />
but also to have an intermediate<br />
layer between screw and nut that<br />
reduces friction further when the<br />
screw is loosened and tightened<br />
several times. This surface coating<br />
is a customised biocompatible lowfriction<br />
coating of the Diamond-<br />
Like-Carbon type.<br />
Since the product has been developed<br />
without hydrogen, the materials<br />
do not risk having the hydrogen<br />
brittleness that other types of<br />
coatings do. The new coating is,<br />
of course, non-toxic – and can be<br />
deposited on almost all materials<br />
such as metals, alloys, ceramic<br />
materials and composites.<br />
The innovative carbonaceous coating<br />
was developed on the <strong>Danish</strong><br />
<strong>Technological</strong> <strong>Institute</strong>’s advanced<br />
PVD coating machine in cooperation<br />
with Elos Medtech Pinol A/S,<br />
a company manufacturing medical<br />
and dental instruments and equipment.<br />
Coating in mass production<br />
The coating is called MediCarb®<br />
and went into mass production in<br />
late <strong>2010</strong>. So far, four companies<br />
among the ten market leaders in<br />
dental applications have received<br />
test samples of the new medical<br />
product. Christian Schäfe Thomsen,<br />
Dental Product Manager from<br />
Elos Medtech Pinol A/S has high<br />
expectations for the new product:<br />
- I’m thrilled about our cooperation<br />
with the <strong>Danish</strong> <strong>Technological</strong><br />
<strong>Institute</strong>. By drawing on their<br />
vast experience with DLC coatings<br />
and excellent understanding<br />
of our challenges and needs, we<br />
have now developed a fantastic<br />
product, which will increase our<br />
turnover and make a difference to<br />
our customers and, above all, their<br />
patients.<br />
The <strong>Danish</strong> <strong>Technological</strong> <strong>Institute</strong><br />
now has three different types of<br />
low-friction coatings at its disposal,<br />
and other industries are also<br />
expected to benefit from the new<br />
coating.
