I had the implant procedure today. What is the validity period of the implant?

Today, I decided to go ahead with the implant procedure that I had been avoiding out of fear. The doctor at Smiling Dental in Ingyedong, Suwon City, had recommended it several months ago, but I kept postponing it because I was scared.

Today, I entrusted my body entirely to anesthesia for the procedure. Contrary to my worries, it was completed quickly and easily. The removal of the remaining part of the gum was done with something similar to a Benzi, which was dizzying, but thanks to the power of anesthesia, the procedure was relatively simple.

The procedure was successfully completed, but one thing I'm curious about is that implants are not permanent either. How long is the validity period of an implant? I would like those with experience to share their thoughts. The doctor says that if properly maintained, it can be permanent... Can we believe that at face value?
