- Abstract:
- The aim of the study was to investigate whether bone marrow aspirates (BMA) and concentrates (BMAC) influence the grafts' stability when added to deproteinized bovine bone mineral (DBBM) within the first 6 months after maxillary sinus augmentation. 26 CT data of 13 patients undergoing bilateral maxillary sinus augmentation in a split-mouth design were evaluated using the Voxim software by comparing the graft volumes 2 weeks after the sinus lift procedure with CT data obtained 6 months later. DBBM with (N = 6) or without tibial BMA (N = 6) and DBBM with (N = 7) and without adding iliac BMAC (N = 7) were used as grafts. Absolute and percentage changes in the graft volumes were evaluated, and the nonparametric Mann-Whitney U-test and the nonparametric Wilcoxon test were performed to determine significant differences between the graft volumes within each single split-mouth group and between the two groups. Overall, the volumes decreased between 15% and 21%. All single groups showed statistically significant decreases over 6 months of healing. The time-dependent changes in volumes between the different groups were not statistically significant (P = 0.818). An evident decrease in graft volume over the first 6 months of healing has to be expected irrespectively of graft composite. Neither BMA nor BMAC seem to have an evident impact. Overaugmentation seems recommendable in two-stage maxillary sinus surgery. © 2013 John Wiley & Sons A/S. Published by Blackwell Publishing Ltd.
