We report a case of desmoplastic ameloblastoma (DA) arising in the maxilla, which was reconstructed using a custom-made titanium mesh tray with particulate cancellous bone and marrow (PCBM) after an autogenous iliac bone graft. The patient was a 35-year-old man who was referred to our outpatient clinic to undergo assessment of a maxillary tumor. A swelling was found between the left lateral incisor and premolars. Radiographic findings showed a “frosted glass-like” lesion. We diagnosed DA on an incisional biopsy. Maxillectomy and reconstruction with an autogenous iliac bone graft were performed in June 2013. In addition, reconstructive surgery using a custom-made titanium mesh tray with PCBM was performed subsequently. After the operation, we placed dental implants and provided the final prosthesis. There has been no recurrence of tumor as of 5 years after the maxillectomy and reconstructive surgery. Furthermore, a good esthetic outcome with recovery of the occlusion function was obtained.
