When there is bone loss it can be corrected by placing the bio acceptable bone or from patient own bone. Not all the biomaterials are same. Please check for the bone graft used.
Bio-Oss is a bone replacement material that is used to increase the body's own bone. Bio-Oss is composed of the hard, mineral portion of natural bone and has a structure very similar to that of human bone. It is therefore well accepted by human bone tissue and serves as a guide-rail for the new bone growth.
