What are the criteria of immediate loading? According to Prof. Branemark, an orthopedic surgeon, the concept of immediate loading was not acceptable. Even removing the restoration from occlusion brings it into function on mastication. Then comes the immediate denture or fixed/removable hybrid bridge of the entire arch. In that case, the concept of taking it out of occlusion makes no sense. I am familiar with the available literature on the subject, but still the issue remains a mystery in my mind. Where is the science? What do you think? Are we lowering the odds of predictability that were at one point very high?
