Abstract :
A rewarding area of Prosthodontics is the rehabilitation of patients with acquired maxillary defects. The utilization
of obturator prostheses stands as the foremost therapeutic approach for rectifying acquired maxillary defects. Obturator is
the prosthesis used to close a congenital or acquired tissue opening, primarily of hard palate and or contiguous alveolar
structures. This intervention yields enhancements in speech, mastication, swallowing, and facial aesthetics, accomplished
through the restoration of oro-nasal separation. Moreover, obturator prostheses have demonstrated the capacity to
ameliorate patients’ psychological well-being and overall quality of life. Notably, hollow bulb obturators offer advantages
such as reduced weight, increased retention, and that prevents fluid and food accumulation. This clinical report describes
the prosthetic approach employed in rehabilitating an acquired palatal defect specifically of type IV per the Aramany
classification employing definitive hollow bulb prosthesis, utilizing CAD/CAM technology.
