Background:
The conventional method of harvesting full cortical bone from the mandibular ramus was reported to have associated complications ranging from postoperative pain and swelling to impaired inferior alveolar nerve function.
Methods:
A modified ramal bone harvesting technique is described in which partial cortical-type bone is harvested from the mandibular ramus and used for an autogenous bone graft.
Results:
Partial-thickness cortical bone was harvested without paresthesia while reducing postoperative discomfort and complications. Sufficient bone was obtained for ridge augmentation and eventual implant placement.
Conclusion:
Non-invasive partial cortical ramal bone harvesting is a reproducible and predictable technique for preventing nerve damage while providing sufficient block bone needed for a dental implant.
