The cast round RPA clasp.
The incorporation of a cast round clasp into the RPA design has been presented. When properly used, the cast round clasp eliminates the need for blockout of the facial aspect of the terminal abutment normally required with the half-round clasp. This technique includes surveying the refractory cast, which ensures optimal placement of the round clasp in relation to the height of contour.
