Synthetic bone

NanOssTM is engineered synthetic bone and is the first material that duplicates the microstructure, composition and performance of human bone. Utilizing nanotechnology, calcium and phosphate are manipulated at the molecular level and assembled to produce materials with unique structural and functional properties not seen before in other calcium phosphate based materials.

Structural NanOss. A 100% dense, highly consistent, crystalline hydroxyapatite or tricalcium phosphate that has nearly the strength of stainless steel. Based on Angstrom's unique ability to combine strength with controlled resorption, NanOss implants will provide the gold-standard benefits of autograft with the strength found in metal or composite devices. Initial applications for the material include suture anchors, ACL/PCL interference screws and interbody fusion cages for spinal surgery.
