Consumption of Alcohol Leading to Implant Complications?

Authors

Dr. Y. asks:

I have been placing dental implants since 2004 and have placed more than 300 but never seen anything like this. I placed 2 implants in #2 and #3 areas after doing a single stage sinus graft using BIOSS. The patient had a shot of alcohol on the first night post-op and 2 days later there was severe inflammation which surprisingly caused teeth #1 and #4 to become slightly mobile. What could be the cause of this and could it be attributed to the alcohol because the surgery was totally atraumatic and routine? Any suggestions anybody?
