Answer to Question #84

The answer isTRUE

The altered cast impression captures the tissues of the edentulous ridges in relation to the way the framework fits in the mouth (not on the cast). Hopefully, the two would be the same but that is not always the case. With an altered cast impression, one also tends to avoid the overextension that is prevalent with a cast made from an alginate impression in a stock tray.
