Synthetic Biocompatible Dental Bonegraft B-OstIN is synthetic biocompatible material composed of elements that occur naturally in the bone i.e hydroxapatite (HAP). B-OstIN is made by wet chemical methods and thereafter converted into porous mass through ceramic processing routes. Similarly to the bone mineral make B-OstIn biocompatible and most Osteo conductive Materila. B-OstIN is most osteoconductive material with helps in bone bonding withing 3 month, fastest of all ceramic constituents. - Ca /  P ratio similar to that of human bone. - Crystalling structure and morphology similar to natural bone. - 60 - 70% porosity with pore size 100 - 300 um
