Previous reconstruction of severely atrophic maxilla with calvarial bone graft and implant supported fixed partial prosthesis - Case report

Abstract

Purposes: Autogenous bone graft is still considered the “gold standard” for bone augmentation of the jaws prior to dental implants placement. In cases of major bone defects, we can relinquish reconstructive techniques using grafts from extra buccal donor areas, such as the calvarial bone graft. Although this technique is well established in the literature, many professionals feel insecure in indicating this type of treatment to their patients, due to the high degree of complexity for the execution of the procedure and not acceptance by the patient. Case report: A female patient, 42-year-old, had undergone reconstructive surgery by means of a calvarial bone graft for pre-maxilla reconstruction prior to dental implants placement in regions of 14 to 24. The graft collection procedure was performed in a hospital setting and under general anesthesia. The grafts were transplanted from the calvarial bone to reconstruct the anterior maxilla. After 7 months, 4 dental implants were placed, allowing a future prosthetic rehabilitation. After the period of osseointegration, screw-retained partial fixed prosthesis was made, returning function and aesthetics to the patient. Conclusions: In view of the clinical case and literature presented, it is concluded that patients with severe maxillary bone atrophy can undergo a successful reconstruction process with calvarial bone grafts and dental implants.
