Rebase
Rebasing is recommended when the denture teeth are not yet worn out but the acrylic denture base material needs to be replaced. A new acrylic base will provide a stable denture without the added expense and time involved in replacing the denture teeth.

Relines
The requirement for Relining occurs as bone and tissue shrinkage occurs changing the fit of your dentures. Relining involves adding new base material to the tissue side of a denture so it fits properly. Relining can restore your denture to a “like new fit”. Relining affects only the fit of your denture and will not change its appearance or other aspects.

Bone and Tissue changes occur due to Resorption (shrinkage) of oral tissue. Resorption takes place over time (months even years) and can be due to:

Weight loss
Loss of teeth
Bone loss in upper or lower jaw
Disease or illness
