Abstract
The clasp assemblies act as the direct retainers of the RPDs without precision attachments. In this chapter, infrabulge and suprabulge of clasp assemblies used in RPD design are described with their specific features. Components of the clasp assembly and factors that affect the retention of the clasp assembly are defined. In addition, the RPI clasp assembly which is used for the distal extension RPDs is explained in details. As clinically important as direct retainers, indirect retention (rests and minor connectors) and its principles to counteract the dislodgment of the RPD are also expressed.
