title: Preliminary impression in patients with microstomia.
abstract: This article describes a preliminary impression technique for edentulous patients with microstomia. Stock impression trays are modified to make sectional impressions of the left and right sides of the maxillary arch. The cast poured into the first impression is positioned in the second impression, which is then poured to make the diagnostic cast.
