Use of a conventional rigid five-unit fixed dental prosthesis is a less than ideal plan of treatment in pier abutment cases due to physiologic tooth movement, arch position of the abutments, and a disparity in the retentive capacity of the retainers. A non-rigid connector is a broken-stress mechanical union of retainer and pontic, instead of the usual rigid connector. An innovative and cost effective way of fabricating a non-rigid connector is presented in this case report.
