HI There!
I just came back from India to get implants. The way it works overseas is you take 2 trips to complete your procedure, spaced about 6 months apart.
My first trip:In the first trip they pull out any teeth that need replacing and then put the implants in, all in one sitting (they knocked me out for the procedure, thank god)

. Let me be honest, this HURTS! Well, not the surgery itself, but the first few days after surgery. But I'm the type of person that would rather get all of the pain out of the way at once, so this method worked out better for me. I'm now wearing a temporary prosthesis over my implants that I can remove.
Second trip:When I go back in a few months the dentist will put permanent veneers over my implants. The great thing about taking 2 trips is now that I've got all of the painful stuff out of the way, I can look forward to that trip to the Taj Mahal MedTrava's planning for me - and I'll be smiling wide with my new teeth! Hehee

Over all its a great experience for me. Take care.
