Objectives 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. Material and methods 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. Results 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). Conclusions 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. [ABSTRACT FROM AUTHOR] |
