PROSTHODONTICS Flashcards
A replica of a prepared tooth for the making of a crown is a
die
advantages of CAD/CAM procedures are/is
no need for provisional coverage
what type of retention is used to reinforce a restoration that has been treated endodontically
post and core/ core build up
when a fixed bridge is fabricated, the teeth supporting the bridge are referred to as the
abutments
retraction cord impregnated with epinephrine is contraindicated for patients with
cardiovascular disease / heart issues
retraction cord is placed with a
blunt packing instrument
the primary function of a provisional bridge is to
maintain the function and aesthetics of the area
when selecting a shade for a crown it is important to use
natural light
the component of a fixed bridge that replaces the natural tooth is the
pontic
another name for a resin bonded bridge is an
Maryland bridge
provisional coverage of teeth is used to
reduce sensitivity and discomfort in a prepared tooth
what material can be used for making custom provisional coverage
self curing acrylic
what type of provisional coverage is indicated for posterior teeth when a true fit is essential
custom formed
a laboratory prescription is signed by the
dentist
preformed polycarbonate crowns are available in a variety of
shapes, sizes, shades
every patient who receives provisional coverage should follow patient instructions which are
not “popping” dental floss in/out of contact points and avoiding sticky foods
regardless of the method used in a dental office, specific criteria must be followed for each fabricated crown or bridge
yes/true
if an aluminum crown is tried in the mouth but not selected for use it needs to be
sterilized before reuse
can a scaler be used by a dental assistant to remove excess cement from a provisional crown
yes
the expanded functions dental assistant has a major role in the fabrication and temporary cementation of a provisional crown or bridge
true
what is a component of a partial denture that determines how far it is seated into the plane of occlusion
rest
what is not an extraoral factor taken into consideration when constructing a denture
salivary flow
a metal device built into a partial denture to relieve occlusal stresses is a
stress breaker
the material used for partial and denture bases is
acrylic resin
the occlusal rims on a denture are used for the records of
vertical dimensions
when a denture is to be relined an impression is taken using
the patients current denture
a preliminary impression is taken in the fabrication of a full denture to
construct a custom tray
a partial denture is held in place on the abutment tooth by the
clasp
the purpose of a tissue conditioner is to
rehabilitate unhealthy tissue supporting prosthesis
the success of a removable prosthesis depends on
healthy mucosa, a good alveolar ridge, strong facial muscles
artificial teeth are constructed from
acrylic or porcelain
occlusal rims are made of
wax
measurements that are used for evaluating a patients bite
centric relation, lateral excursion, protrusion, retrusion
when dentures are not in the mouth they must be stored in a
moist, airtight container
an immediate denture is one that is placed immediately after
the extraction of teeth
most partial denture frameworks are made from
metal
a complete denture supported by two or more remaining natural teeth or implants is a
overdenture
a denture would be polished by a
laboratory lathe
when sending a partial or denture to a lab it must first be
disinfected
when a patient has his or her dentures relined the patient should be informed that they will be without the denture for
8-24 hours
