Dr. R. asks:
This is the first case I have done where I placed the dental implant on the day I extracted the tooth. This was in #14 area [Maxillary Left First Molar]. There were problems right from the beginning.
Now after 4 months post-op the upper 2 threads of the implant are visible and exposed to the oral cavity. I believe the dental implant has peri-implantitis. Is there anything I can do at this point to save this dental implant? Additionally, what causes peri-implantitis and how can I prevent it in the future?
