lesson 1 Flashcards
Branch of dentistry pertaining to the restoration and
maintenance of oral function, comfort, appearance
and health of the patient by the restoration of the
natural teeth or the replacement of missing teeth and
contiguous oral and maxillofacial tissues with artificial
substitutes or by both.
PROSTHODONTICS
Branch of prosthodontics concerned with the
replacement or restoration of teeth and contiguous
structures for edentulous patients by artificial
substitutes that are removable from the mouth.
Removable Partial Denture
Used in the course of the treatment for short time
intervals for the reason of esthetics, mastication
and occlusal support and convenience for
conditioning of the patient to the acceptance of an
artificial substitute for missing natural teeth until a
more definite dental treatment can be provided.
Interim Denture
Serves as a temporary denture to which teeth will
be added as more teeth are lost and that will be
replaced after post-extraction tissue changes have
occurred.
TRANSITIONAL DENTURE
Used for treating or conditioning the tissues that
are called on to support and retain the denture
base.
TREATMENT DENTURE
A synonym for a prosthesis that is usually
temporary, claspless, and made of acrylic resin, and
that replaces anterior teeth only.
BUTTERFLY DENTURE
A term used to designate a temporary prosthesis
made as an interim measure to help the patient
become accustomed to an artificial replacement.
Same as temporary denture.
PROVISIONAL DENTURE
Used to provide the patient with a tideover
cosmetic facade until missing anterior teeth can be
restored with a more definitive type of
replacement.
TEMPORARY DENTURE
(CLASSIFICATION OF RPD ACCORDING TO LOCATION)
●Replaces missing tooth or teeth in one side of the
arch only (except for extensive class II Kennedy’s
classification.
UNILATERAL
(CLASSIFICATION OF RPD ACCORDING TO LOCATION)
Replaces missing tooth or teeth on both sides of
the dental arch.
BILATERAL
(CLASSIFICATION OF RPD ACCORDING TO SUPPORTING
STRUCTURES)
Receives support from the abutment teeth which
are located anteriorly and posteriorly from the
edentulous space
TOOTH BORNE
(CLASSIFICATION OF RPD ACCORDING TO SUPPORTING
STRUCTURES)
Receives or derives support entirely from tissues or
underlying mucosa and bone (RPD without clasps).
TISSUE BORNE
(CLASSIFICATION OF RPD ACCORDING TO SUPPORTING
STRUCTURES)
Supported by both abutment teeth, mucosa and
underlying bone. This is referred to as “TRUE RPD”
and has at least a free end extension.
TOOTH-TISSUE BORNE
CLASSIFICATION OF RPD ACCORDING TO MATERIALS USED
- One- piece casting
- One-piece casting (skeleton type)
- Individually cast clasp assembly (Assembled type
w/ cast clasp) - Wire clasp assembly
- Retention plate partial denture
Consists of parts of partial denture (except for
denture base and pontics) that are casted in
oneplace
ONE-PIECE CASTING
Same as one piece casting except for the skeleton
like framework which was to be filled mostly by
resin materials
ONE - PIECE CASTING (SKELETON TYPE)
Only the clasps assembly are casted and the rest
are filled by resin materials.
INDIVIDUAL CAST CLASP ASSEMBLY
Utilizes orthodontic wires for its clasps and the rest
are to be filled up by resin materials.
WIRE CLASP ASSEMBLY
Without any clasps assembly, uses the full coverage
of the palate as the means of support and retention
of the denture
RETENTION PLATE PARTIAL DENTURE
INDICATION OF RPD
- Distal extension caries
- Long edentulous areas
- Restoration of facial contours
- As a transitional prosthesis
- Alteration of vertical dimension
- Children and adolescent
- Shortened life expectancy
- Unblemished abutment
- Extreme atrophic residual ridge
- Patient with diabetes
- Obliteration of cleft palate
- Cross arch bracing
CLASSIFICATION METHOD FOR PARTIALLY EDENTULOUS
ARCHES
1. CLASSIFICATION BASED ON RESTORED CONDITION
A. Cummer’s Classification
B. Bechet’s Classification
CLASSIFICATION METHOD FOR PARTIALLY EDENTULOUS
2. CLASSIFICATION BASED ON UNRESTORED CONDITION
A. Austin-ledge Classification
B. Kennedy’s Classification
C. Applegate’s Classification
KENNEDY’S CLASSIFICATION
Bilateral edentulous areas located posterior to
the remaining natural teeth
CLASS I
KENNEDY’S CLASSIFICATION
Unilateral edentulous area located posterior to
the remaining natural teeth
CLASS II
