The Single Denture Flashcards
the most common situation:
Maxillary arch is edentulous
Mandibular arch has natural / restored teeth
natural teeth have a greater — force against opposing denture
chewing
natural teeth do not move in — as denture does
function
cannot control placement of
opposing teeth
drifting/tilting puts natural teeth far from
optimal positions
centripetal resorption
Routine resorption pattern following
extraction of teeth results in a smaller maxilla
when compared to dentate arch.
Maxilla resorbs UP and INWARD!
horizontal arch discrepancy is created when
maxillary arch narrows and becomes shorter in AP direction
a crossbite may be required to
direct occlusal forces to the bearing area
Maxillary CD opposed by mandibular
anterior natural teeth:
