Density of bone formed after sinus augmentation with Nanobone versus that of bone formed after sinus lift with tenting technique : Preliminary study

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.
