Atlas of Cases 221 a b d f Figure 20B.1 a Panoramic image of a 32-year-old male with Pindborg s tumor CEOT to the left. b Panoramic image 6 months after the operation. The border between graft and the angular area is still sharp and the bony union is not complete. c Situation 14 months after the operation. There is complete bony union between graft and mandible. However areas of bone resorption are seen within the graft. d Situation 27 months after the operation. The plate has been removed and the height of the graft is preserved but bone resorption within the graft seems to continue. e Cross-sectional tomography 27 months after operation. Two consecutive cuts. There is good cortical lining of the graft but it has a central area of radiolucency bone resorption . f A diagrammatic representation of e . 222 C. Lindqvist D.

Soderholm c Figure 20B.2 a Panoramic image of a 40-year-old female 4 years after primary operation for SCC of mandibular gingiva of the molar area and 20 months after transplantation of an iliac bone graft. The plate has fractured. There is good bony union medially between graft and mandible but a defect at the angular border. b Cross-sectional tomography also shows the plate fracture. A thin bony bridge is seen lingually. c Panoramic image 5 months later. There is complete union between graft and mandible the plate has been removed. 20B.
