Osteoporosis causes bones to become weak & brittle due to low bone mass & bone tissue deterioration. Chronic & progressive Most common origin of bone disease in U.S. Fractures transpire easily. Primary cause of fractures in elderly. Bone formation should match bone resorption. Osteoblasts Build (form) new bone & generate organic matrix & mineralize bone. Osteoclasts Breaks down bone & cause bone resorption. Osteocytes Maintain bone by directing when/where bone remodeling is to occur. Parathyroid

Abstract Bone graft procedures‚ in particular maxillofacial repair‚ account for half of the orthopedic procedures done in the US each year. Infection is a major issue in surgery‚ and should be of primary concern when engineering biomaterials. Silver is of renewed importance today‚ as it has the ability to potentiate antibiotics against resistant bacterial strains. In order to reduce long term infection risks‚ it is necessary for the scaffold to maintain a silver ion release for the length of the
