Although several theories have been put forward, an important factor of bone regeneration is not yet exactly known. But the vascularization to bone wound is said to be a very important factor. The author has made a radiographic observation of correlation between vascularization of inferior alveolar artery and osteogenesis. The patient has a benign tumor in the right lower molar region. Partial osteotomy was performed from first premolar to third molar so as to include the inferior alveolar artery. At postoperative 37th day, thin and slight radiopaque appeared in the bone defect from the distal cut end part of the inferior alveolar artery (Cut end part 4mm in size). The radiopaque gradually developed and reached the cut end of medial bone at 706th day (10mm in size). The phenomenon suggested that new bone developed vigorously by new blood vessel and developed to protect the supply route of blood from strong irritation.
