A survey on the utilization of disposable quadrant articulators.
This study evaluated utilization of the six most popular disposable quadrant articulators presently used in crown fabrication. Most general practitioners and crown and bridge laboratory technicians reported that they frequently or always used disposable quadrant articulators for single units and simple three-unit fixed partial dentures. All evaluated articulators demonstrated an inability to maintain and repeat the centric stop position. The disposable quadrant articulator, used in combination with dual-arch impressions, is a viable method for fabricating single and short-span restorations. While a nonrepeatable centric stop was present in all six articulators evaluated, the method was considered a time-efficient and cost-saving alternative to traditional all-metal simple-hinge articulators.
