Failing Dental Implants: Anything I Can Do to Rescue These?

Authors

Dr. C. asks:

I have a new patient who presents with two implants in #23 and 26 sites [mandibular right lateral incisor and mandibular left lateral incisor; 32,42] supporting a 4-unit fixed partial denture replacing teeth #23-26. The implants have considerable bone loss but are not mobile. Is there anything I can do to rescue these ailing and failing implants?
