This document discusses the parts and surfaces of a complete denture. It describes the impression/intaglio surface, polished/external/cameo surface, and occlusal surface of a denture. It also outlines the main parts of a complete denture: the denture base, denture flange, denture teeth, and denture border. Finally, it provides brief descriptions of the functions of a complete denture including mastication, aesthetics, and phonetics.

2. Surfaces of a complete denture
1. Impression/intaglio surface
2. Polished /external/cameo surface
3. Occlusal surface

4. Impression surface: The portion of the denture surface
that has its contour determined by the impression,
syn, IMPRESSION AREA, INTAGLIO SURFACE

5. Cameo surface: The viewable portion
of a removable denture prosthesis; the
portion of the surface of a denture that
extents in an occlusal direction from the
border of the denture and includes the
facial, lingual and palatal surface; it is the
part of the denture base that is usually
polished, and includes the buccal and
lingual surfaces of the teeth.

6. Occlusal surface: A surface of a
posterior tooth or occlusion rim that is
intended to make contact with an opposing
occlusal surface.

10. PARTS OF A COMPLETE
DENTURE
1. Denture base
2. Denture flange
3. Denture teeth
4. Denture border

11. Denture base
The part of a denture that rests on the
foundation tissues and to which teeth are
attached.
 Forms the foundation of the denture.
 Helps to distribute and transmit the forces
acting on the denture teeth to the basal tissues.
 Adequate extension of the denture base helps in
providing retention and support.
 Denture bases made of acrylic resin or metal.

12. Acrylic resin denture base
Most commonly used material
Easy to fabricate.
Economical
Supplied as powder (polymer) and liquid
(monomer).

13. Metal denture base
Fabricated using Gold, Gold alloys,
Chromium-Cobalt or Nickel-Chromium alloys.
Difficult to fabricate
Easier to maintain

14. Denture flange
The part of the denture base that extends from the cervical
ends of the teeth to the denture border.
Provides peripheral seal and horizontal stability.
Classified according to the vestibule where it extends as—
labial, buccal and lingual.

15. Labial flange
The portion of the flange of a denture that occupies
the labial vestibule of the mouth.
• Provides lip support.
• V-shaped notch is provided in the labial flange to
accommodate the labial frenum.

16. Buccal flange
The portion of the flange of a denture that
occupies the buccal vestibule of the mouth.
• Provides the cheek support.
• Relief is provided to
accommodate the buccal frenum.

17. Lingual flange
 The portion of the flange of a mandibular denture
that occupies the alveololingual sulcus
 Should maintain contact with the tissues of the floor
of the mouth.

18. Denture border
 1. The margin of the denture base at
the junction of the cameo surface and
the intaglio surface.
 2. The peripheral border of a denture
base at the facial, lingual, and
posterior limits.

19.  Responsible for maintaining the peripheral
seal.
 Should be smooth and polished.
 Overextended denture borders may cause
ulcers and hyperplasia.
 Underextended borders result in loss of
peripheral seal and compromise retention.

20. Denture Teeth
A term commonly referring to an artificial
tooth used in the fabrication of a resin base
prosthesis.
