Radiolucencies Around The Implant

Alan, a dentist, asks us:
I have a question regarding a lower arch oral rehabilitation case that I have done 1 year ago. The patient had severe peridontally involved
teeth which were all removed to be replaced with
5 dental implants.

The dental implants were placed by an oral surgeon. It was done as an immediate case and a fixed lower denture was placed on the same day. The prosthetic part was completed by me after about 2 months of waiting for the surgeons OK to proceed.

My problem is that during recent examinations, I have found that one of the dental implants was mobile. I suspected the abutment was loose and as I didn’t have the proper torquing wrench, I referred my patient back to see the oral surgeon. I was told by the surgeon that there were no problems. However during his most recent visit, I still found the dental implant mobile and it was painful for the patient. I took an xray and confirmed my worst fear: radiolucencies around the dental implant!

I am not sure what should be the correct way of telling the patient especially after the surgeon who checked it said it was OK. How would you guys handle this case? He currently has a screw retained
fixed lower prosthesis. I am rather new to the implant field and have been only doing the
prosthetic part so far. I would appreciate any comments and suggestions. Thanks!
