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.
