It started with C-3 and the last MRI showed C-1 to C-7. The only bisphosphonates that have ORN risk are the long term injectibles. The oral versions are actually used to treat ORN of the mandible. It makes no sense to me that something used to treat ORN can cause it. Some studies I looked at were using people with radiated mandibles and the rate of ORN was the same as people not taking bisphosphonates, around 10%.
One of the reasons the mandible has such a high rate is the size and density of the bone.
