Impression procedures and construction of a sectional denture for a patient with microstomia: a clinical report

This article describes a modified impression procedure and a method of fabricating a 2-piece collapsible denture for a patient with limited oral opening as a result of the resection of a precancerous lesion on the maxillary lip. Fabricating the denture in 2 pieces (a smaller anterior piece and a larger, hinged, collapsible posterior piece) enabled the patient to place and remove the denture.
