Abstract :
Maxillary defects following surgical resections or infections severely impair mastication, deglutition, speech, and esthetics, making prosthetic rehabilitation with obturators a vital treatment option. Aramany Class VI defects, characterized by bilateral posterior maxillary teeth present with anterior teeth missing, present unique biomechanical challenges due to the lack of anterior support and unesthetic appearance. Conventional cobalt–chromium frameworks, though widely used, have disadvantages such as weight, metallic taste, and esthetic limitations. This case report presents the rehabilitation of an Aramany Class VI defect in a 32-year-old female with a digitally designed and CAD/CAM-milled polyetheretherketone (PEEK) obturator. Intraoral scanning and computer-aided design were used to fabricate a lightweight, biocompatible, and esthetically pleasing PEEK framework with an attached hollow bulb obturator. The prosthesis demonstrated excellent fit, retention, and patient satisfaction, significantly improving function and esthetics. This report underscores the potential of PEEK combined with digital workflows as an innovative alternative to conventional metallic frameworks in the management of complex maxillary defects.
