I was born with cleft lip and palate in 1969. I'm looking at total replacement top and bottom. I'm far from a normal case.

you need to have complete analysis,first.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,



 shape size and even color,



 you will have that smile you always wanted back with a great confort and support.



 



All on 4 By Nobel Biocare,



its the best way to go if what you want is a screw retained  bar,



that you do not remove ,



 also you will have a strong solution,



 extractions (if you need them) and immediate setting of implants are done at the same proceedure,



and within acouple of days, you will be able to enjoy, a great smile ,



 with strenght and confort,



that smile you always wanted, this is the moment, shape, size and even color, you will be able to change.



 But yes, you have asolution!

I used to make a lot of obturators for cleft palate patients in the late 1970's thru the 1980's.  It has been several years now.  Implants can be used to make a snap in denture.  I used them to secure dentures with obturators.The fistula may be closed with sliding flap without bone graft.  Placing implants requires bone.  Bone grafts can be used to prepare fpr implants.
