Bone loss occurs through out the life of a dental implant no matter what we do to it (eg. platform switching, nano surface technology). This is more so if the implant has been in the mouth for over 10- 15 years. Disease processes will exacerbate the rate of bone loss. Bone around an implant does not remodel in the same way as a natural tooth and cannot response in a way that a tooth does. The presence of periodontal ligament is vital to the long term maintenance of the bony ridge. How do we incorporate these factors into our long term treatment planning?
