The aim of this study was to evaluate differences in ossification of the 2 forms of demineralized bone matrix (DBM)-putty and powder-radiographically, using digital densitometry on panoramic radiographs in maxillary sinus floor augmentation procedures. Twelve subjects needing bilateral maxillary sinus floor augmentation for the placement of osseointegrated implants were included in this study. The left and right maxillary sinuses were augmented in the same session in each patient using the 2 preferred forms of DBM-putty and powder-during the same session. One sinus was augmented with DBM putty form and the other sinus was augmented with DBM powder form randomly. Every patient had a total of 4 panoramic radiographs taken, preoperatively and in the first, third, and sixth month postoperatively. The densitometry measurements were taken from each step of the aluminium step-wedge, from both sinuses from different points a total of 3 times, and the average of these measurements was calculated. The amount of mineralization in each graft material in every radiograph was clarified by the appearance of a difference in the equivalent aluminium thickness, and the obtained results were statistically evaluated. The results showed that there were no significant differences between two graft materials statistically. These two graft materials could be good alternatives in sinus lifting procedures because of less morbidity, lower price, and good ossification. The results indicate that 2 different types of DBM achieved good ossification in the sinus lifting procedure, and there is not a considerable distinction in these 2 forms.
