Patients with minor defects of the alveolar ridge and hard palate can easily be treated by surgical closure, while patients with larger defects are more amenable to prosthetic restoration. The case report describes the rehabilitation of a dentate maxillectomy patient with a definitive closed hollow bulb cast partial obturator. A tripod retainer design was chosen for direct retention in the case. The tripod design consisted of a T-bar clasp placed on the left first central incisor and two embrasure clasps with buccal retention and palatal bracing components between the right first & second premolar and right first & second molar. A complete palate major connector was designed to ensure uniform distribution of functional load across tissues. The remaining teeth, the palate, and the rest provided support for the prosthesis. Prosthetic rehabilitation of the defect with a definitive obturator thus seals tissue openings in the palate, improves deglutition, speech, mastication, aesthetics, and significantly improves quality of life.
