This document discusses special dentures, which are dentures that have been modified from conventional dentures for aesthetic purposes. It describes several types of special dentures, including cheek plumper dentures, which have a detachable component to improve cheek support, Cu-Sil dentures that encircle remaining teeth to aid retention, and hollow dentures, which have a cavity to reduce the weight of maxillary dentures. The document also explains uses for duplicate dentures, flexible dentures, immediate dentures, internally weighted dentures, and liquid supported complete dentures.

3. SPECIAL DENTURE
 Special dentures are also called as
unconventional dentures. This
name is given due to modification
given to the conventional dentures.
These modifications are generally
for esthetic purposes. The dentures
may be complete or partial
dentures.

5. TYPES
 Characterized dentures
 Cheek plumper
 Cu-Sil denture
 Duplicate dentures
 Flexible denture
 Hollow denture
 Immediate denture
 Internally Weighted denture
 Labeled denture
 Liquid Supported complete denture

6.  It is the general characterized modification of the
denture for the esthetic purposes. The
modifications may be change in form or color of
the denture.
 Indications:
1. High smile line
2. Socially active
3. Stage performers

7. CHEEK PLUMPER
 This modification is characterized by
fixed or detachable component that is
placed in the mid posterior region to
improve esthetics by providing support for
sunken cheeks.

9. Cu- Sil
DENTURE
 These are special dentures with a silicone gasket around
abutment teeth to aid in retention by encircling the teeth
and maintaining seal
 Indication:
• Patients with few remaining teeth
• Patients contraindicated for overdenture
• Patients not wiling for extraction for complete denture.
 Advantages:
 It minimizes the forces on abutment while giving primary
retention. No invasive procedure like endodontic treatment
or abutment reduction is required. It is easy to repair and
inexpensive.

11. DUPLICATE DENTURE
 These dentures are made as either exact
replica of previous denture or with slight
modification in denture of satisfactory
service.
 Indications:
 Patients asking for a spare of denture.
 Patients treated with immediate dentures
that require replacement.
 Patients with worn dentition but satisfied
with fitting of old denture.

13. FLEXIBLE DENTURE
 These dentures are partial or complete dentures
fabricated by special material that are not rigid
like acrylic dentures and have flexing properties
that allows a comfortable fit.
 Indications:
 For TMJ splints
 Bilateral inoperable undercuts
 For patients allergic to acrylic monomer
 Advantages:
 More esthetics since metal clasps are
eliminated. Flexibility of the material allows to
be inserted in undercut areas without providing
relief.

16. HOLLOW DENTURE
 These are the maxillary dentures that have hollow
cavity within their designing in the prosthetic teeth
and the denture base just above the ridge to make
the denture light weight.
 Indications:
Patients with increased inter-ridge space because of
increased ridge resorption to reduce the weight of
maxillary denture.
 Advantage:
 Prevents fall of denture due to its weight under the
effect of gravity.

18. IMMEDIATE

20. Internallyweighted denture
 These type of dentures are designed with
incorporation of some additional
components within the body of mandibular
denture to increase its weight to aid its
retention and stability.
 Advantage:
 Improved stability is achieved by added
weight to the denture without altering its
esthetics. It allows for relining of the
dentures if required in future which is not
possible in metal base dentures.

22. LABELED DENTURE
 Thesetype ofdenturesare fabricated with somemarkings that may
be written name ofthe patient, a photograph, barcodeor metal
strip, a microchip with patient details for purpose of identification.
 Indications:
 For forensicpurpose and identification ofpatients in mass disasters
or road side accidents when patient is unableto communicate.
 Advantages:
 Easy and quick method for identification. Thesedenturesdo not
requireany expensive materials. They arehelpful in identification of
dentureswherein family there aremultiple denturewearers.

24. LIQUID SUPPORTED COMPLETE DENTURE
 These dentures have a flexible base which is liquid filled to
provide a cushioning effect to the ridge mucosa. They
continuously keep on adjusting with the resorbing ridge to keep
it well adapted.
Indications:
1) Patients with flabby ridge.
2) Patients with diabetes showing rapid bone resorption.
Advantages:
 Provides flexible base on intaglio surface and with rigid support
through other surfaces. It is comfortable for the patients with
rapid bone resorption.
