The main benefit of dental bone fillings is to restore a certain amount of bone, so that patients with insufficient bone can meet the conditions for implantation. After the bone volume is sufficient, implantation or normal restorative treatment can be performed, so bone powder is mainly used for patients with bone defects or bone resorption. However, it is very expensive to fill the bone powder, a few grams of bone powder costs several thousand dollars, and the failure rate is very high. The current bone powder is all small bovine bone, which is still different from normal human bone, and even after several years of change, it is still a foreign body existing in the mouth, so there is still a difference between bone filling powder and its own alveolar bone.
