Autogenous
bone grafts from the mandibular ramus are a known source of inadequate
bone volume scenarios of the residual
alveolar ridge. However, the conventional block-type
harvesting technique cannot prevent
bone marrow invasion, which can cause
postoperative complications such as
pain, swelling, and
inferior alveolar nerve injury. This study aims to suggest a complication-free
harvesting technique and present the results of
bone grafting and
donor sites. One
patient received two
dental implants with a complication-free
harvesting technique that involves creation of ditching holes with a 1 mm round bur. Sagittal, coronal, and axial
osteotomies produced grid-type cortical squares using a micro-saw and a round bur to confirm the cortical thickness. The grid-type
cortical bone was harvested from the occlusal aspect, and the
harvesting was extended through an additional
osteotomy on the exposed and remaining
cortical bone to prevent
bone marrow invasion. The
patient did not suffer postoperative severe
pain, swelling, or
numbness.After 15 months, the harvested site exhibited new
cortical bone lining, and the grafted area had healed to a cortico-cancellous complex with functional loading of the implants. Our
technique, grid-type
cortical bone harvesting without
bone marrow invasion, allowed application of autogenous
bone without
bone marrow invasion to achieve acceptable
bone healing of the
dental implants and to regenerate the harvested
cortical bone.
