Window's Impression Technique for Anterior Fibrous Maxillary Ridges

This article is aimed at modifying conventional window’s impression technique for making impression of edentulous flabby maxillary ridges. Vinyl Polysiloxane (VPS) impression material was preferred over conventionally used metallic oxide, due to ease of use and dimensional accuracy. The authors used VPS putty consistency on the periphery and regular body for the whole impression. This combination of material consistency gives selective pressure impression. More over the window over the flabby area give the very mucostatic impression of the displaceable area. The authors found the proposed technique superior over Watson’s technique in regards of convenience, time consumption, comfort of the operator and patient.
