for the time and place, in life. I was scuba diving every weekend and training for a Padi Divemaster. I had to have my dentist make special mouth plates, for my regulators. after a while that go to expensive. I had a Plate made, for the 4 teeth that were missing on the right side of the mouth. cheaper, than the implants. I paid 1400.00 for the plate ( that have been there now 18 years) I inquired about upgrading, but the price was too much. My brother in law, suggested going to brazil, and having the work done. airfair & a place to stay, for the work to be done was cheaper then going to a local dentist by thousand of dollars ( just something to thing about )
