Denture Rebasing
The process of refitting a denture by replacing the denture base material without changing the
occlusal relations of the teeth. Rebasing may include adding to the denture base to compensatefor resorptive changes to subjacent structures.
REBASING/RELINING/SOFT LINER
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 reuired when tissue changes occur due to resorption/atrophy !shrin"age# from$

IS A SOFT LINER RIGHT FOR YOU?
ermanent soft liners provide comfort and relief for individuals with$
%. -everely receded or flat gums that do not tolerate the stress of dentures
'. hronic soreness
(. ums with prominent or sharp bony areas
-oft relines do offer some advantages over hard denture bases$
%. linical evidence indicates that almost everyone tolerates soft liner materials
'. 0ith soft liners, many denture wearers report that they can chew food more comfortably!a significant number of denture wearers with chronic discomfort have experienced greatrelief#
(. ) proven technology, soft liners have been offered to patients for over '1 years, and overthat time the materials and technology have steadily improved

-oft liners reuire regular follow2up visits with a +enturist to examine the fit of dentures, the
health of a patient’s oral tissues, and to ensure professional cleaning.
The reuirement for relining occurs when bone and tissues change due to shrin"age.
ossible causes may be$
• ost immediate dentures
• Tooth loss
• 0eight loss
• 3one loss in the upper or lower jaw
• -ic"ness or disease
• eneral physiological aging
The bite position, existing teeth and acrylic base!s# must be in good condition and not worn or
stained to provide a reline procedure.
)n impression of your oral tissue is ta"en inside your denture!s# to provide a wor"ing model.
4ew acrylic base material is added to your denture to produce a correct fit. The appearance ofyour dentures will not change.
REBASE
+enturists in most cases have no way of trying the denture!s#. The procedure is similar torelining. The difference being is that, a rebase replaces all the pin"2acrylic denture base material.
The existing teeth remain in the exact same place.
• Reasons for rebase procedure$
• 3ro"en denture
• 0ea"ened or old pin" denture base
• Immediate denture

Denture Liners
Material applied to the tissue side of a denture to provide a soft lining to the parts of a denture coming in
contact with soft tissue. It cushions contact of the denture with the tissues.
Denture Relinings
The process of refitting a denture by replacing the denture base material without changing the occlusal
relations of the teeth. Rebasing may include adding to the denture base to compensate for resorptive
changes to subjacent structures.
