ABSTRACT:
An improved dental full arch and impression checkbite frame which includes an outer lingual arch and an inner labial arch which are each provided with a longitudinally extending slot for receiving and supporting therein a porous membrane which is adapted to form the support for the mass of impression material for making an impression, the respective slots defining an upper frame portion and a lower frame portion. The respective inner and outer arches are rigidly interconnected at their corresponding distal ends by a cross link. At the proximal end of the dental frame, there is provided a handle having offset bifurcated portions, whereby the bifurcated portions are respectively connected to the upper frame section and lower frame section. A rigid frame is thus defined that is free of any appreciable movement that can compromise the accuracy of a model or cast made thereby.
