Bone grafting is needed to ensure proper fixation of the implant. Depending on the condition of the jaw ridge, its volume and bone density (after studying computer images), a decision is made about the type of length and diameter of the future implant, the place and angle of its installation.
If the width and strength of the bone is sufficient to securely adhere to the entire body of the implant, then the graft is unnecessary since the socket is small enough to accommodate the implant’s diameter.
