Radiographic and clinical photographs of our case. (A) Panoramic radiograph exhibited a giant odontoma and a left impacted third molar located deep to the mandibular inferior border (arrow). (B) A coronal view of CBCT images revealed the proximity of tooth 38 to the left IAN canal (arrow). (C) An axial view of CBCT images revealed the proximity of tooth 38 to the left IAN canal (arrow). (D) Sagittal view of CBCT images. (E) The bone window in the retromolar area was created for excision of the giant odontoma. (F) The bone screw (arrow) was placed on the occlusal surface of tooth 38. (G) Orthodontic forces were applied by an elastic band (arrow) connecting to the bone screw between 34 and 35 (arrow) to make tooth 38 move forward. (H) A CBCT image showed approximately 2-mm forward movement of tooth 38 (arrow). (I) The panoramic radiograph also showed approximately 2-mm forward movement of tooth 38 (arrow). (J) A clinical photograph showed tooth 38 extracted. (K) A screw hole (arrow) was placed into the occlusal surface of tooth 38. (L) The particulate marrow cancellous bone was obtained from the right iliac crest. (M) The bone defect was filled with particulate marrow cancellous bone. (N) The follow-up image of 8 months after surgery indicated successful bone regeneration (arrow). (O) One year after surgery, the follow-up panoramic film indicated stable bone volume (arrow). (P) One year after surgery, the follow-up CBCT images indicated stable bone volume (arrow). (Q) One year after surgery, the clinical photograph showed good wound healing.
