ERIN_SADDLE STABILIZATION

Question 1

what are different ways to control rotation?

Answer 1

you can use indirect retention

• design new clasps with mesial rests.
• AND best saddle extension and fit into the soft tissues

Question 2

what is the purpose of the altered cast technique?

Answer 2

you want to equalize support derived from the edentulous ridge and abutment teeth

Question 3

describe what is meant by “two support systems”

Answer 3

soft tissue which is displaceable
and hard tissue which is not
this is obviously seen with class I and II because you have some kind of saddle extension

Question 4

what is the single most important factor in minimizing the abutment tooth movement?

Answer 4

fit of the base

Question 5

what are the indications for distal extension base stabilization?

Answer 5

ALL MN DISTALS
SOME MX distals
SOME long span Class IV with the ridge owl support the RPD
-depressible displaceable soft tissue (the flabby ridge)
need to feeding peripheral extensions
