Reconstruction and Implant-Supported Rehabilitation of an Iatrogenically Caused Maxillary Alveolar Defect

Implant Dent. 2019 Oct;28(5):510-513. doi: 10.1097/ID.0000000000000910.


Defects of the oral and maxillofacial region may arise from several reasons such as trauma, infection, cyst, tumor, medication related osteonecrosis of the jaw, and misuse of some irritant agents. For reconstruction, autogenous grafts remain the gold standard among the alternatives. In our case, a 42-year-old woman referred to our clinic for implant-supported fixed bridge rehabilitation of her edentulous and defected left 2nd premolar and 1st molar region. In examinations, devitalizing agent-dependent large defect was observed. Anterior iliac crest (AIC) grafting technique was preferred for reconstruction. Consecutively, 16-week bone healing and 3-month implant osseointegration periods were uneventful. After fabrication of the implant-supported fixed bridge, the patient was followed up for 2.5 years with no signs of bone resorption, gingival inflammation, and pain. AIC grafting and implant-borne fixed bridges seem stable and satisfactory methods for large maxillofacial defects.
