Blockout technique for impressions of teeth with increased open gingival embrasures

A dental technique is described that blocks out enlarged gingival embrasures to eliminate distortion of an impression and the resultant cast for removable partial or fixed partial dentures. This procedure consists of injecting polyvinyl siloxane impression material in embrasures to form custom blockout wedges. This technique provides a simple method for clean, customized blockout of potentially damaging undercuts that can distort impressions and casts. The ultimate accuracy of the cast results in a precise definitive prosthesis.
