Assessing new bone formation after maxillary sinus augmentation surgery using right anterior iliac crest bone marrow aspirate and cancellous allograft.

The aim of this retrospective study was to assess the change in the alveolar bone height following sinus augmentation surgery utilising a combination of right anterior iliac crest bone marrow aspirates and allogeneic cancellous bone, as observed through cone-beam computed tomography (CBCT). A total of 46 patients who underwent CBCT scans taken before and after sinus augmentation surgery were evaluated. The alveolar bone heights were compared over time. Average and frequency measures, as well as a Student's t test were performed to determine significant differences between the graft height between the preoperative and postoperative alveolar bone heights. Overall, a statistically significant increase in alveolar bone heights from a mean of 5.44 mm ± 2.9 m to 12.49 mm ± 4.8 m was observed on the postoperative CBCT scan. The mean postoperative CBCT was 23 months (range: 5-59), p < 0.01. In conclusion, the use of bone marrow aspirates from the right anterior iliac crest combined with allogeneic cancellous bone materials can be successfully used to create increased bone height for pre-implant site grafting.
