In order to maintain bone remodeling balance, it is important to keep enough Ca absorption from the intestine. Vitamin D is required to increase Ca absorption from the gut.

Renal impairment is the main cause of deterioration of the activation of vitamin D. Aging is associated with the dev...

However, bone graft substitutes have been developed and used because of the limited amount or donor site morbidity of the autogenous bone graft. Many kinds of bone graft substitutes including osteoconductive materials and osteoinductive materials are used for improving bone healing. Osteoconductive materials help to provide a three-dimensional structure to support the ingrowth of th...
