RELINES
The requirement for relining occurs when bone and tissues change due to shrinkage.
Possible causes may be:
The bite
position, existing teeth and acrylic base(s) must be in good condition and
not worn or stained to provide a reline procedure. An impression of your oral
tissue is taken inside your denture(s) to provide a working model. New acrylic
base material is added to your denture to produce a correct fit. The appearance
of your dentures will not change.
REBASE
Denturists in most cases have no way of trying the denture(s). The procedure
is similar to relining. The difference being is that, a rebase replaces all
the pink-acrylic denture base material. The existing teeth remain in the exact
same place.
