Definitive RPDs  are
constructed after extensive diagnosis,
treatment planning, and thorough
preparation of the teeth and tissues for the
prosthesis. The length of service of
definitive RPDs is intended to be many
years (customarily 5-10 years).
There are three types of RPDs or
partially edentulous arches based on the
tissue(s) which provide support. Support is
the resistance to movement of the denture
toward the edentulous ridge. RPDs maybe
tooth supported, tissue supported, and toothtissue
supported. This is a simple
classification system and very meaningful
because the principles of RPD design depends, to a great extent, on its supporting
tissue
