A quadrant tray and bite registration as an alternative to dual-arch impressions for fixed prosthetics: A clinical and dental laboratory technique

The technique described in this article is a relatively simple method that can be used with ease to produce accurately mounted casts. The advantages of this technique are reduced risk for distortion of the impression material/tray complex, the separation of the impression and the IOR steps, the ability to inspect the die prior to articulation, and a reduction in other laboratory complications associated with the traditional dual-arch method. The technique has all of the advantages of the dual-arch technique while eliminating most of the disadvantages. When this protocol is utilized properly, definitive restorations should need only minimal occlusal refinement in maximum intercuspation, resulting in reduced chair time and a cost savings to the practice and the patient.
