(1) a clasp the arms of which are bar-type extensions from major connectors or from within the denture base; the arms pass adjacent to the soft tissues and approach the point of contact on the tooth in a gingivoocclusal direction; (2) a clasp consisting of two or more separate arms located opposite each other on the tooth; the bar arms arise from the framework or from a connector and may traverse the soft tissue; one arm (bar), the retentive arm, usually terminates in the infrabulge (gingival convergence) area of the tooth; the other, the reciprocal arm, usually terminates on the suprabulge (occlusal convergence) area. SYN: Roach clasp.
