You have posed excellent questions. A prime consideration about how thi
needs to be designed has to do with the severity of the bite, the forc
of the bite, the lateral excursions, and the dentist's judgemen
(guess-timate) of same!
For many people, there is not a huge amount of lateral, side-to-sid
displacement so two implants may do the trick to prevent the backward
slippage.
On the upper, if you eliminate the palate, you eliminate the "suction.
This means that two implants will never do the job. Why not? Because th
denture will rotate around the fulcrum, that is the line bisecting th
two implants.
STEP ONE is always to be sure that the dentist has plenty of dentur
experience. If the dentures themselves prove to be a problem, try tw
lower mini-implants for stabilization.
If a better approach is desired, prepare to pay more, much more.
