Removable partial dentures (RPD) will continue to be one of the primary methods used to restore missing dentition for the foreseeable future. We use RPD to replace missing posterior teeth, especially in the absence of distal abutments Rpd is preferred when there is excessive residual ridge resorption What are the 3 main principles the need to be satisfied in rpd designing? An advantage of this restoration is the avoidance of an extensive palatal or lingual major connector; however, the design provides no cross-arch stabilization, which can result in easy dislodgement1 and additional complications.2 Consequently, an RPD with a cross-arch .
