• The challenge of conventional RPD design is to
balance the requirements of retention and support
while minimizing damage to natural dentition and the
supporting ridge.
• While the flexible denture simplifies the design &
enable the RPD itself to balance the simultaneous
requirement of retention ,support & stability.
