The success rate of bone grafting for dental implants is still very high, probably between 80% and 95%. When dental implants are performed with insufficient bone volume, bone grafting is required. The main reason for this is that the alveolar bone resorbs and shrinks due to the long period of time that the teeth are missing, resulting in insufficient bone volume in the alveolar bone. At this time, bone grafting is needed to increase the width and height of the alveolar bone, and then dental implant surgery can be performed. The success rate of bone grafting, although high, depends on many factors. These include the extent of the bone graft, local blood flow, extension of the mucosal flap, and autoimmune factors (implant rejection). Bone grafting is usually performed according to the size of the defect, and the success rate of pure allograft bone powder is low, which needs to be mixed with autogenous bone for better treatment results.
