You will do fine. I opted to have the abutment implanted at the same time as my second surgery for tumor removal, therefore it was done under general anesthesia, and I was in the hospital for four days afterward because of the translab surgery recovery time required.
I can honestly say neither the translab incision nor the abutment implant have given me any unmanageable pain. I did have Dilaudid IV for the first 24 hours, a couple of oral Dilaudid the second 24 hours, only Tylenol thereafter. I would have to say most of that was needed because of the translab surgery, not from the abutment surgery.
My instructions were to wait until the doctor removed the stitches from the incision and the bandage from the abutment (8 days post-op) before washing my hair. Then, no restrictions from there on ...... just wash hair with my normal shampoo and keep it clean on a daily basis. I have had no issues with healing whatsoever. It is still a tiny bit tender when I touch around it at a month post-op. Counting the next 60 days until my "turn on" date!
Best wishes and many prayers for a successful surgery tomorrow.
