(26 cards)
branch of Dentistry pertaining to MAINTENANCE and
RESTORATION of oral function, comfort, health and general
appearance of patient by REPLACING missing tooth or teeth
and its contagious structure with an ARTIFICIAL SUBSTITUTE
*Prosthodontics
art and science of SUPPLYING or PROVIDING REPLACEMENT
of the missing body part
prosthetic
ARTIFICIAL REPLACEMENT of the missing part of the human
body
prosthesis
resists VERTICAL forces of dislodgement
Retention
resist displacement by FRICTIONAL, HORIZONTAL, or
ROTATIONAL stresses
resistance
receive all their support from the ABUTMENT TEETH
tooth-(supported) borne
supported at one end by NATURAL TEETH, which essentially
do not move, and at the other end by the DENTURE BEARING
TISSUE (mucosa overlying bone) which moves because of the
resiliency of the mucosa
tooth - tissue borne
base extending posteriorly on a removable partial denture
distal extension partial denture
portion of an implants that supports and retain dentures
abutment
portion of the residual bone and its soft tissue covering
remains after tooth extractions
residual ridge
JOINS the components on one side of the arch to those on the opposite side
major connector
used to RETAIN and PREVENT DISLODGEMENT
commonly called “clasp” or “clasp unit”
direct retainer
direct retainer composed of
REST, RETENTIVE ARM,
RECIPROCAL ARM, MINOR CONNECTOR
PREVENTS or RESISTS MOVEMENTS or ROTATIONS of the
base away from residual ridge
indirect retainer
a rigid extension of RPD which contacts a tooth to DISSIPATE forces
rest
FLEXIBLE SEGMENT that engages an undercut on an abutment
and is designed to retain the denture
tapered end
retentive arm
resist tooth movements in response to the retainer arm
reciprocal arm
COVERS the residual ridges and supports denture teeth
denture base
plane which guides movement
two or more PARALLEL AXIAL SURFACES ON ABUTMENT teeth which limit the path of insertion
guide plane
a dental prosthesis to be used for a short interval of time for
reasons of esthetics, mastication, occlusal support, or
convenience
provisional or interim denture
the measurement of a tooth from the lingual to the vestibular in its greatest buldge
height of contour
the portion of the surface of an object that is BELOW THE height of contour
undercut
an instrument used to determine the relative parallelism of two or more axial surfaces
dental cast surveyor
resurfacing the tissue side of a denture with a new material to
FILL THE SPACE that exists between the original denture
contour and the altered tissue contour
relining
