Its been almost two years now that I went to Rio Dental in Juarez for my dentures. I had already had all remaining teeth removed near my home in WNC six months prior to going to Mexico. At Rio I had 8 mini implants installed (4 upper, 4 lower) to retain the dentures. I've had no problems and am still very happy with my decision. The whole process, including air fare & motel while there, was less than $3,000. The cost of removing teeth was about $2,200 of which insurance paid $1,100.
Hope this helps and good luck with whatever decision you make.
