Immediate maxillary denture impression

Abstract The technique described may consume a little more time in making the impression, but the results obtained more than justify the use of this time. The procedure provides for (1) areal coverage, (2) an accurate denture border, (3) a valve seal without interference with functional movements of oral structures, (4) accurate adaptation of the denture to the tissues without injurious tissue displacement, and (5) determines the correct posterior extension of the denture, (6) creates a postdam which not only completes the valve seal but which also compensates for dimensional changes in the denture base due to shrinkage during processing, and (7) minimizes postinsertion adjustments.
