Any patient with one or many missing teeth is a good candidate for dental implants. Anyway, there are certain chronic diseases that disqualify some individuals in getting this procedure done. If you suffer from a chronic condition, talk to a dentist and see if you are or not a good candidate for dental implants.
I can't help much with personal experiences, but know a few persons who travelled to overseas clinics bacause it is cheaper. If you want to compare prices, you can look on dentalimplantsfriends com
