After tooth loss, alveolar ridge resorption is a common phenomenon, which alters the size and shape of the host bone available for the dental implant placement. In the era of prosthetic driven implant dentistry, the final prosthesis type and design dictates the number, size and the ideal implant position. In clinical practice, though patients often demand osseointegrated implants to replace their missing teeth; the deficiency of bone volume is the primary reason for avoiding such treatment options. The solution to such situations lies in the re-establishment of the ridge height consistent with prosthetic design and with suitable load-bearing lamellar bone for implant placement and long-term stability. Despite recent advances in bone grafts and bone-substitute technology, the use of autogenous bone grafts continues to represent the "gold standard" in implant site reconstructive surgery. The mandibular symphysis (chin bone in interforaminal region) is a favorable donor site as it has an excellent risk-benefit ratio. Several reconstruction procedures by using chin graft have been proposed to increase alveolar bone volume both vertically and laterally to prepare the ridge for a correct placement of oral implants. This article reviews the various aspects of chin grafts, wherein the regional surgical anatomy, various incision designs, surgical protocols for harvesting and the possible clinical and esthetic complications of chin grafts have been discussed.
