However, in addition to these considerations, it is of fundamental importance that RPDs be designed so that they interfere as little
as possible with plaque control and do not damage the oral tissues.
Several studies of the outcomes of RPD treatment
have been performed in different parts of the world.
There appears to be, however, no unanimous opinion on RPD design principles, although one national survey demonstrated that many principles receive the support of a majority of prosthodontic specialists.
The RPD design principles are not based on clinical research and therefore are not evidence based.
However, there are
a number of reports of adverse effects on the oral tissues and a high frequency of patient dissatisfaction.
