You don't necessarily need to take the bone yourself when you implant the teeth, it depends on the patient's bone defect. When the patient's bone defect is small, the application of artificial bone powder can meet the needs of bone grafting and implantation. In this case, the patient does not need to take the bone himself. When the patient's bone defect is particularly large and the application of artificial bone powder can not meet the needs of bone grafting, it is necessary to take bone from the patient.
