A patient presenting with severe microstomia (PDI Class IV) was unable to insert a maxillary complete denture. Sectional final impressions were made using two impression materials and an interlocking custom tray. A folding record base was used for maxillomandibular relationship records. A novel folding maxillary denture with a custom hinge and plunger attachment to lock the denture in the open position was fabricated. The patient was able to insert the collapsed denture, open it intraorally, and enjoy successful masticatory function.
