Bone grafting technique to increase interdental alveolar bone height for placement of an implant

We have developed a simple, one-step technique for chin bone onlay grafting combined with simultaneous implant placement to increase alveolar bone height without any support system. We have used it to place 14 implants in nine patients; eight recovered uneventfully but, in the other one, the wound broke down and the exposed chin bone necrosed. After a mean follow-up period of three years (range 1.5-4.7) the clinical and radiological outcome has remained good in those eight patients.
