Runner bar modification for mandibular removable partial dentures

David M. Bohnenkamp

Research output: Contribution to journalArticlepeer-review


Breakage of a segment of an acrylic resin denture base of a mandibular removable prosthesis may result from inadequate retention and support. The runner bar modification can be a solution for this problem, especially where excessive crown length is to be restored in the mandibular anterior region. A technique is described for placement of a 14-gauge (1.7 mm) round wax runner bar that conforms to the anterior arch form on the removable partial denture wax-up. Wax vertical struts are added between the denture base retention and the runner bar. Improved retention and rigidity, without compromising esthetics and function, can be obtained through use of this procedure.
