Nobel Active Implants: thoughts on failure issues?


I purchased the Nobel Active implant system, and thought it would be great. Unfortunately, I started getting implant failures with this implant system. Of 40 implants that I placed, 9 failed to integrate. I want to make it clear that all implants I placed in the last 5 years were via surgical guides and all of them had enough bone all around. I have had very good results with other implant systems I placed, such as Biomet 3i, MIS Implants (5% failure or less), and Hiossen Implants (I did not have any failures after 500 placements). Has anyone else had issues with the Nobel Active? Please share your experience, and any information why I maybe getting more failures from Nobel Active. Thank you for sharing your thoughts.
