Final Impression
Tooth supported partials have support provided by teeth and have what kind
of final impression? - correct answer ✔single stage impression --> need to
capture anatomic form of the ridge
tissue supported partials have support provided by - correct answer ✔teeth
and edentulous ridge
tissue supported (kennedy class I and II) partial require what kind of
impression? - correct answer ✔dual stage impression or secondary
impression
corrected or altered cast to provide the maximum extension for support and
comfort
must capture functional form of the ridge
for a tooth supported RPD you are capturing the anatomic form of the ridge
which means what? - correct answer ✔captured at rest, no pressure
tooth supported RPD requires ___________ support from the ridge - correct
answer ✔minimum
tooth supported RPD capturing ridge at rest can result in more movement of
the RPD which can lead to what? - correct answer ✔abutment loosening
capturing the functional form of the ridge for a tissue supported RPD means
what? - correct answer ✔tissue under pressure... provides maximum support
, why do you have to be careful when taking impression of tissue supported
RPD under pressure? - correct answer ✔overly displaced tissue can become
inflamed, impaired, and accompanied with bone resorption
factors influencing the support of a distal extension base - correct answer
✔contour and quality of residual ridge
max and mandibular stress bearing areas
firm and dense soft tissue
cortical bone
round ridge form
denture base coverage ... the broader the greater the support
what role does type and accuracy of impression have in influencing support of
a distal extension partial? - correct answer ✔viscosity of impression
materials
rigidity of impression trays (no distortion when removed from mouth)
impression techniques
how do you want denture base to fit against tissues? - correct answer
✔intimate contact between tissue surface of the denture base and the tissue
surface of the residual ridge
on distal extension design you would move the rest where? - correct answer
✔from distal to the mesial... will provide less stress on abutment teeth
how does number of artificial teeth and width of their occlusal surfaces impact
support of distal extension base? - correct answer ✔fewer teeth = less
occlusal force = less stress placed on abutment teeth
