Lec 1.2: Enumeration Flashcards
Functions of teeth (4)?
- Aid in digestion = mastication.
- Preserve and maintain health of supporting structures and prolong life of remaining teeth.
- Phonetics
- Esthetics
3 Branches of prosthodontics?
Fixed, removable, maxillofacial
Objectives of RPD construction? (4)
- Improve phonetics
- Restore masticatory function
- Restore and improve appearance
- Carry out procedures in a manner that wouldn’t cause harm and discomfort to px
Consequences of partial edentulism? (11)
- Undermined cosmetic appearance
- Loss of tooth support
- Loss of masticatory efficiency
- Tipping and migration of teeth
- Extrusion of teeth
- Attrition and depression of teeth
- Loss of vertical dimension
- Mandibular deviation
- TMJ Dysfunction
- Loss of alveolar bone
- Traumatic gingivitis
Indications of RPD (7)?
- Length of edentulous span
- Abutment tooth
- Periodontal support of remaining teeth
- Cross arch stabilization
- Excessive bone loss
- Patient perception
- Economic reasons
Classification according to location?
Unilateral RPD
Bilateral RPD
Classification according to supporting structures?
Tooth borne
Tooth and tissue borne
Classification according to materials used?
One piece casting
Skeleton type casting
Individually casted clasp assembly
Wire clasp assembly
Retention plate partial denture
General principles for RPD? (10)
1) More than 2 posterior teeth or 4 anterior teeth are missing
2) Canine and 2 of its adjacent teeth are missing
3) No distal abutment tooth
4) Multiple edentulous spaces
5) Teeth adjacent to edentulous spaces are tipped, they cannot be used as an abutment for a fixed prosthesis.
6) If periodontally weakened teeth are present near the edentulous spaces
7) Teeth with short clinical crowns
8) Insufficient number of abutments
9) Severe loss of tissue on the edentulous space
10) Old patients (age factor)
