Going a bit further here: If the chances of success of a single implant
are .95, the chances of complete success for two implants must be .95 X .95=
..9025.

Going further yet, for multiple units:
Three Implants .95 ^3 = .8574
Four Implants .95 ^4 = .8175
Five Implants .95 ^5 = .7738
Six Implants .95 ^6 = .7351

As you can see, even though 95% success per unit looks like a pretty good
number, the chances of complete success would seem to degrade rapidly with
multiple units so (based on this math only) some extra units may indeed be worth
considering if it would be more expensive to add them later.
