Radiographic follow-up evaluation of sinus augmentation with deproteinized bovine bone and implant installation after loading.

Computed tomography (CT) has been used in diagnosis and implant treatment, and CT can be used to assess the dimensional stability of graft materials after maxillary sinus augmentation. A 50-year-old male patient was treated for the simultaneous placement of implants with sinus augmentation and two post-operative CT scans were performed after the delivery of the prosthesis at 9 months and 15 months after the operation. There were no significant changes in alveolar bone height and the buccal window seemed to show remodeling over time. The continuity of the defect and the cortication were apparent in the 15-month post-operative CT scan. Implants installed simultaneously with sinus augmentation were well in function and the graft material seemed to be stable in maintaining tissue dimensions after the loading of the implants. The presented results need to be validated in further large case series or case-controlled studies.
