This report describes a partial digital workflow for the fabrication of a mandibular complete denture for a patient with microstomia. Computer-aided design and computer-aided manufacturing technology was utilized to 3D print a sectional custom tray with a unique design. The sectional custom tray was used to make a conventional border molded impression of the edentulous arch to fabricate a flexible complete mandibular denture for a 58-year-old female patient with scleroderma and microstomia. This treatment resulted in a successful prosthetic outcome and high patient satisfaction.
