Simplified impression technique and foldable denture fabrication for a patient with microstomia

Ritu Saneja, Bappaditya Bhatacharjee, Pavan Dubey, Atul Bhatnagar


Background: Constricted opening of the oral aperture may linger any dental treatment. The adequate mouth opening is very much necessary for any procedure related to prosthodontics. The restricted opening may lead to difficulty in recording the accurate impressions, designing of the dentures and even the ordinary tasks of insertion and removal of the prosthesis. As the absolute height of the stock impression tray is approximately 1–1.5 cm, the impression tray and final prosthesis to be use in microstomia patient has to be laboratory modified. Aim: The aim of this case presentation is to rehabilitate an edentulous patient with severely reduced mouth opening with three-piece sectional denture to make prosthesis foldable during removal. Methodology: A sectioned custom tray was made to achieve accessibility of intraoral structure, and the hinged maxillary denture with intraoral magnet was fabricated to ensure comfortable insertion of the complete denture prosthesis. Conclusion: The sectional hinge denture with adjunct use of intraoral magnet can be comfortably inserted and removed by patient with restricted mouth opening. It is cost effective and comfortable approach for rehabilitation of microstomia patient. Clinical Significance: Impression technique chosen was very comfortable for the patient. As complete denture prosthesis was fabricated in three parts, insertion and removal of the prosthesis was easy.
