Unfortunately you are not able to get snap on smile without posterior (back) teeth since you have nothing for the teeth to snap on to. You would be looking at a partial denture to replace your missing teeth
SNAPINDENTURES OR ALL ON4 , BY NOBEL BIOCARE.
There are 2 ways of restoring this , the first one could be with Snapindentures,
with 8 minimplants, upper and 8 minimplants lower,
you will have a strong support with snapindentures,
and you will have a great result within a couple of days...
Unfortunately without any teeth you are not a candidate for a snap on smile as it uses your existing teeth as support. You would need dental implants placed and an implant supported denture.
