Abstract

Aim: Comparing the density of bone formed after sinus lifting and augmentation with Nanobone graft to that of the newly formed bone after non-augmented sinus lifting with tenting technique.
Materials and Methods: A total of 12 maxillary sinuses requiring lifting and augmentation procedures were divided into two groups: Group 1: comprised six patients in which grafted maxillary sinus lifting with Nanobone graft procedures were performed, Group 2: comprised six patients in which non-grafted maxillary sinus lifting procedures were performed.
Simultaneous implant placement was performed in both groups. Implants were left for six months after placement in bone to ensure complete osseointegration before loading.
Results: Immediately post-operative, after 6 months and after 9 months, the mean bone density of grafted group showed statistically significantly higher value than non grafted group. This is due to the continued bone formation in the grafted group.
Conclusion: There is significant increase in density of bone formed after augmented sinus lifting with Nanobone more than that of newly formed bone after non-augmented sinus lifting in the first nine months after the maxillary sinus lifting operation with simultaneous implants placement.
