curasan AG - specialists in regenerative medicine - today received
510(k) approval by the FDA for Cerasorb® M Dental and Cerasorb®
Perio.

Cerasorb® is a synthetic bone regeneration material that is fully
resorbed by the body and replaced with autogenous bone. Cerasorb® M
Dental is a second-generation product, featuring even faster
resorption and bone replacement. It is used in regions exposed to
lower loads and complements the classic Cerasorb®.

In addition, the company has developed a product by the name of
Cerasorb® Perio, which is designed specifically for bone defects
caused by periodontitis. Thus, curasan has taken a major step forward
in terms of developing indication-specific Cerasorb® products.

"In autumn 2004, we introduced our own sales organisation for the US
dental market. Cerasorb® M Dental and Cerasorb® Perio underline our
ambitions as a leader within the field of state-of-the-art bone
regeneration. Our target group will see the extension of our
Cerasorb® portfolio as evidence of our commitment to the marketplace
and will support our sales activities in this area," said curasan’s
CEO H.D. Rössler.

About curasan AG: curasan AG (ISIN: DE 000 549 453 8), an
exchange-listed company, is a leading innovator within the growth
