Was abutment properly seated and tightened?

Follow-up re: implant at tooth #31. Pain was totally gone after placement of abutment and crown. However the oral surgeon had to remove on day of the submitted panoramic. "A 15 blade was used to make a sulcular incision. A prosthetic handpiece was used to access the abutment screw. When the abutment screw was tightened, the entire fixture abutment complex moved and the fixture abutment and crown were taken out as one unit. There is a large amount of granulation tissue and purulent tissue at the distal aspect of the implant site. The side was curetted aggressively. Mesial bone was intact and healthy." The explanation given me was "The end result was loss of osteointergration, but this was secondary to infection on the fixture. A non-union would have caused spinning at the uncovering stage. When i exposed the fixture, there was granulation tissue and pus on the fixture and the bone. Usually on the non-intergrated implants we will see a thin area of fibrous non bony union. So yes and no, the was inadequate integration but secondary to infection." Same day, a new, identical Nobel Active 5.0 was placed adjacent. A cover screw was placed and closed with sutures. Cerasorb M mixed with sterile venipuncture was used. Two weeks later Widened PDL (periodontal ligament space) was detected at tooth #30. The cover screw of the new implant became exposed three weeks after placement and sits in a crater. Small ulcer on throat and two canker sores on cheek adjacent to site. So far no pain, blood, swelling or pus, but temp is below normal for me, runny nose and persistent salty taste in mouth.
