Branches in prosthodontics
A condition in
which natural

• chew food for swallowing and digestion.
2- Speech (phonetics):
• the teeth either natural or artificial assist the tongue and
lips to form some of the sounds of speech.
3- Appearance (aesthetic):
• is influence by the shape of jaws together with the position
and occlusal relation ship of the teeth.
4- Health of the alveolar bone and the tempro-mandibular
joints (T.M.J).
Types of dental removable prosthesis
1. Conventional Complete dentures
2. Partial dentures
Acrylic base
metallic base
3. Overdentures
 A complete
denture supported both by mucosa
and by a few remaining natural teeth that have
been altered, as by insertion of a long or short coping,
to permit the denture to fit over them.
4. Immediate dentures
 A removable artificial denture that is placed in the
mouth immediately after the surgical removal of all
remaining teeth at the same appointment as the
tooth extractions to maintain normal appearance and
the ability to chew food. It may be complete or partial.
