Interlocking sectional custom tray technique for closed-mouth impression with simultaneous occlusal registration in maxillofacial defect restoration: A dental technique

Abstract

Impression making for obturator fabrication in patients with a maxillectomy and extensive maxillary defects can be challenging because of anatomic complexity, restricted mouth opening, and difficulty in achieving an effective seal. This article presents an interlocking sectional tray technique in which the intaglio surface of an existing obturator is merged with intraoral scan data to design a custom tray without a cast. The interlocking sectional tray system enables separate recording of the defect and dentate areas in a closed-mouth position with simultaneous occlusal registration.
