Correlation between clinical and CBCT-based crestal soft tissue and bone parameters in posterior edentulous mandible.

Ideal bone considered for adequate implant stability is that with thick cortical bone surrounding a cancellous bone. This study, perhaps for the first time not only aimed to study the association among Crestal soft tissue thickness, Cortical bone thickness and Cancellous bone density but also to find gender related variations of the three parameters. The crestal soft tissue thickness was evaluated clinically and through CBCT. An increase in crestal soft tissue thickness is significantly associated with an improvement in thickness of cortical bone but cancellous bone density value had a little tendency to change.
