Surgical Considerations in anterior mandibular region

During the harvesting of a monocortical symphyseal block of bone from the mandibular symphysis region (autogenous block bone graft), incisive branch of the inferior alveolar artery is often severed as it continues medially and anastomose with the artery of the opposite side if proper care is not taken. The apical limit of bone harvesting is 5mm coronal to the inferior border of the chin, coronal limit is 5mm apical of the apex of the anterior teeth and lateral limit is 5mm mesial to the mental foramen.
