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:
- Loss of weight
- Loss of teeth/Loss of bone
- Aging
- Disease or illness
Is a soft liner right for you?
Permanent soft liners provide comfort and relief for individuals with:
- Severely receded or flat gums that do not tolerate the stress of dentures
- Chronic soreness
- Gums with prominent or sharp bony areas
Soft relines do offer some advantages over hard denture bases:
- Clinical evidence indicates that almost everyone tolerates soft liner materials
- 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)
- 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.
