Definition
An artificial replacement of an absent part of the
human body
The art and science of supplying artificial
replacement for missing parts of the human
body.
The branch of dentistry that deals with the
replacement of missing dental and oral and
craniofacial structures
A condition in which complete set of natural
teeth are present in the mouth.
A condition in which the mouth is without teeth.
A condition in which some of the natural teeth
are lost
An artificial substitute for missing natural teeth
and adjacent tissues.
A removable dental prosthesis that replaces the
entire dentition and associated structures of the
maxillae or mandible
A partial denture that can be removed and
placed in the mouth.
A partial denture that is cemented to natural
teeth or dental implants
It is a denture that occludes against some or all
natural teeth
A complete or removable partial denture
fabricated for replacement immediately
following the removal of natural teeth
A removable partial or complete denture that
covers and rests on remaining natural teeth,
roots or dental implants
A prosthesis used to close a tissue
opening(congenital or a acquired)
A prosthesis that utilizes dental implants for
retention, support and stability
The resistance to displacement towards the basal
tissue or underlying structures
The quality inherent in the dental prosthesis
acting to resist the forces of dislodgment along
the path of placement away from the tissues.
The quality of a removable dental prosthesis to
resist displacement by functional horizontal
stresses.

Natural Versus Artificial Teeth:

Natural teeth are firmly rooted in the bone of the jaw so they can incise, tear
and finely grind food.
• Artificial teeth rest on the oral mucosa and are held there by weak forces while
subjected to powerful displacing forces, so, their efficiency as a masticatory
apparatus is limited.
Objectives of Complete Denture
1-Restoration of the masticatory function
2- Restoration of the normal appearance.
•
Loss of teeth agingfalling of lips and cheek
•
Loss of teeth resorption of alveolar bone
3- Correction of speech defects resulting from loss of natural teeth
•
Proper length and labiolingual position of the teeth
4- Preservation of alveolar bone & Tempromandibular joint
•
Restoration of chewing  minimize the rate of alveolar atrophy
5- Satisfaction & comfort of the patient
Ill fitting denture discomfort
Surfaces of a complete denture
1- Polished surface: the outer (external) surface of the denture that carries the
artificial teeth. It includes the facial, lingual, and palatal surfaces facing the cheeks,
lips, and tongue.
•
Labial, buccal, and lingual surfaces of teeth are part of the polished surface.
2- Occlusal surface: the portion of the denture surface that makes contact with its
antagonist (opposing occlusion).
3- Fitting surface: the surface that fits on the tissues. Also called basal surface,
tissue surface, and impression surface

Introduction to pre-clinical complete denture
Components of a complete denture:
1. Artificial teeth
2. Denture base: the part of the denture that rests on the tissue foundation and to
which artificial teeth are attached.
– Retention and stability.
– Carry and support teeth.
– Represents oral mucosa.
– Support lips and cheeks.
a. Denture borders: the margin of the denture base at the junction between the
polished and the impression surfaces.
b. Denture flanges: the vertical extensions of the denture base that extend from
the cervical margin of the teeth to the borders of the denture.
•They are named according to their location as follows:
- Buccal flange: related to cheeks and occupies buccal vestibule.
- Labial flange: related to lips and occupies labial vestibule.
- Lingual flange: portion of mandibular denture related to tongue and occupies
lingual sulcus.
c. Palatal portion: that portion of the maxillary denture related to the palate.
