Ridge Augmentation for Implant Placement Using Chin Graft;A Case Report

하악골 전방부 골이식술후 임프란트의 매식;증례보고

Severe alveolar ridge deficiency can prevent ideal implant placement. Ridge augmentation procedures are necessary to regain lost alveolar structures. The corticocancellous block bone graft was harvested from the mandibular symphysis. This block bone was fixed to the lateral aspect of the ridge with titanium screws. Seven months later, the autogenous bone graft was reentered and sufficient bone volume was gained to allow implant placement. The fixation screws were removed and 3I implants were inserted. No complication and postoperative alteration in chin contour were observed. This report demonstrates that chin graft offers a predictable alternative in the reconstruction of ridge deficiency for implant placement.
