When I was a teen my orthodontist pulled two of my bottom teeth to make
room. Normal enough to pull permanant teeth for this procedure. Except -
that no one looked at the ex-rays.

Appears the crowding was caused by a couple of fairly well rooted baby teeth
that both fell out before I was 30. Of course the two pulled teeth were
right next door and had the two baby teeth been removed moved instead it
would have been abou tthe same overall effect.

So now I have a 1/4" gap behind each of my lower canine teeth, then the
molars start. I've often considered implants for those 2 holes - the rest of
my teeth are fine.

When there's not enough bone left in the maxilla (upper arch) to place an
implant of sufficient length, the surgeon lifts the membrane at the floor
of
the sinus, and places bone grafting material (cadaver, autogenous, bovine,
synthetic, etc) iunderneath the membrane in the space he/she created.
This
gives the surgeon enough bone thickness to place a sufficiently long
implant
in the area...so that it doesn't protrude into the sinus space.
