Long-term results of secondary alveolar bone grafting using a technique to harvest pure calvarial cancellous bone: Evaluation based on plain radiography and computed tomography

Our cancellous bone harvesting technique resulted in successful graft survival without serious complications, including dural or brain injuries. Although the ilium is widely accepted as the optimal donor site for secondary alveolar bone grafting, the calvarium could be an alternative donor site that results in equivalent outcomes.
