Rebasing is usually done when the denture teeth have not worn out in comparison to the denture base material. It is a process of retrofitting dentures by replacing the entire acrylic denture base with new acrylic, which provides a stable denture without replacing the denture teeth.

Relining consists of adding a new layer of acrylic to the tissue side and existing base of a denture so that its fit is improved.

Rebasing/Relining affects and improves only the fit and will not alter a denture’s original appearance nor will it improve or correct a poor bite.

Relines are required when tissue changes occur due to resorption/atrophy (shrinkage) from:

1. Loss of weight
2. Loss of teeth/Loss of bone
3. Aging
4. Disease or illness

Is a soft liner right for you?

Permanent soft liners provide comfort and relief for individuals with:

1. Severely receded or flat gums that do not tolerate the stress of dentures
2. Chronic soreness
3. Gums with prominent or sharp bony areas

Soft relines do offer some advantages over hard denture bases:

1. Clinical evidence indicates that almost everyone tolerates soft liner materials
2. With soft liners, many denture wearers report that they can chew food more comfortably (a significant number of denture wearers with chronic discomfort have experienced great relief)
3. A proven technology, soft liners have been offered to patients for over 20 years, and over that time the materials and technology have steadily improved

Soft liners require regular follow-up visits with a Denturist to examine the fit of dentures, the health of a patient’s oral tissues, and to ensure professional cleaning.
