Maxillary Hollow Bulb Obturator: A Paradigm shift

A 50‑year‑old male presented to the Department of Prosthodontics and Implantology with partial maxillary edentulism, a history of uncontrolled diabetes, and a mucormycosis infection which resulted in resection of the hard palate, leading to an Aramany Class VI maxillary defect. On intraoral examination, he presented with an abrasion on the inferior turbinate within the Figure 1: Armany Class VI maxillary defect Figure 3: Primary impression defect due to the existing prosthesis, which was a rigid, two‑piece, magnetic acrylic obturator.


Primary impressions were made using a medium‑fusing compound (Y‑dents, MDM Cor poration) in the defect area and an irreversible hydrocolloid material (tropicalgin, zhermack) , followed by the fabrication of a special tray and final impressions with low‑fusing compound (DPI Pinnacle Tracing Sticks) and a monophase polyether wash impression (Aquasil, Dentsply). The prosthesis was acrylized in heat‑cured denture base resin.
