Are all on four dental implants sufficient to prevent bone loss and the associated excessive aging of the face?

I have read several articles lately that promote the concept that a single lost tooth is enough to trigger bone loss. If that is true, how can all on four prevent bone loss (a concept that is routinely promoted in the dental industry)? Certainly four implants will not provide the same measure of pressure to the bone. Have I misunderstood what I read? Do all on four merely offer a partial solution to bone loss that can never compare with a full set of teeth?

Nothing compares to keeping teeth

Bone remains when under tension, whether from a root of a tooth or from an implant.  All on Four will help, but where there are no implants/roots, bone will shrink over time.  If bone preservation is a goal, then more implants is better.  Is it clinically significant?  Probably not.

The next question is the restoration, as most all on four treatments use a hybrid denture that can taste/smell funny over time.  A Deutsch Removable Bridge should be considered (using the same implants/design).

All on 4 concept

all on 4 is indicated in case where proper bone is not present due to bone loss. it is last option . so in ideal cases all 4 is not indicated. if proper bone is present in that case maximum numbers of implants are indicated [7 in upper jaw + 7 in lower 7].
