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.

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.
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.
