lesson 2 Flashcards
PARTS OF METAL FRAMEWORK
- Major Connector
- Minor Connector
- Direct Retainer
- Rest
- Denture Base retaining element
- Proximal Plate
- Tissue Stop
Part of the partial denture that connects the part
of the prosthesis located on one side of the arch
with those on the opposite side of the arch.
MAJOR CONNECTOR
TYPES OF MAJOR CONNECTOR (According to Location)
- Maxillary Major Connector
- Mandibular Major Connector
TYPES OF MAXILLARY MAJOR CONNECTORS
- Single Palatal Strap
- Antero-posterior Palatal Strap (Double Palatal
Strap) - U-shaped Palatal Strap (Horse-shoe Strap)
- Full Palatal Connector
TYPES OF MANDIBULAR MAJOR CONNECTORS
- Lingual bar
- Linguoplate
- Lingual bar with continuous bar retainer
(Kennedy’s bar) - Labial bar
- Swinglock
Unit of the partial denture framework that
connects the other component of the partial
denture to the major connector
MINOR CONNECTOR
Any form of attachment applied directly to an
abutment tooth used for fixation and retention
of the prosthesis.
RETAINER
TYPES OF RETAINER:
- Direct retainer
- Indirect retainer
A clasp or attachment to an abutment tooth for
the purpose of retaining the removable partial
denture in place and limits the displacement of
the removable partial denture in an occlusal
direction.
DIRECT RETAINER
Any part of the removable partial denture
framework which assists the direct retainer in
preventing displacement of an extension base by
functioning through lever action on the opposite
side of the fulcrum line.
INDIRECT RETAINER
TYPES OF DIRECT RETAINER:
- Extracoronal
a. Circumferential (clasp)
b. Bar type - Intracoronal (precision and semi-precision
attachment)
Some of the components that act as indirect retainers are
as follows:
- Auxiliary occlusal rest
- Direct retainers
- Major Connectors
Component of the partial denture placed on the
abutment tooth in a prepared rest seat, so as to
limit the movement of the denture in a gingival
direction:
REST
BASIC TYPES OF REST:
- Occlusal rest
- Incisal Rest
- Cingulum or Lingual rest
Extension of the finish line which serves to
support the denture base by retaining the resin
base to the framework. This do not contact the
oral mucosa
