Stronger, More Successful Bone Implants May Result from a Layered Approach
September 3rd, 2007
Researchers from the American Dental Association Foundation (ADAF) and the National Institute of Standards and Technology (NIST) have developed a new method for layering two kinds of biomaterials into one strong, yet porous unit that may lead to improved reconstruction or repair of bones. Currently, calcium phosphate cements (CPCs)—water-based pastes of powdered calcium and a phosphate compound that form hydroxyapatite, a material found in natural bone—are used for reconstructing or repairing skeletal defects, but only in bones that are not load-bearing (such as those in the face and skull). Macropores built into the CPCs make it easier for new bone cells to infuse and,...
