Dogman, I had HBO before and after implants were placed in my lower jaw. Truly a cake walk compared to all other treatments. My sessions were about 90 minutes, 5 days a week. I was in a single chamber and could watch movies to pass the time. A side effect is that it generally alters your vision temporarily. In my case, happily, I no longer need the glasses I needed to read. That was four years ago, so I guess the improvement is here to stay, as are the implants. Go for it!
