Summary

Treatment of tumors in the paranasal region often requires maxillectomy procedures. While surgical reconstruction is preferred, prosthetic reconstruction using obturators becomes necessary when surgery is not feasible. Obturators separate oral and nasal cavities, restoring functions like chewing, speech, and facial aesthetics, while alleviating psychological distress. The emergence of rapid prototyping (RP) technologies since 1995 has revolutionized prosthetic construction. RP techniques like stereolithography and 3D printing enable layer-by-layer production of accurate 3D models from computer designs. Combined with imaging like CT and MRI, RP allows creation of highly precise extraoral facial prostheses. For intraoral defects, integrating 3D CAD and RP can enhance prosthetic outcomes compared to conventional gypsum models, although obtaining accurate impressions remains challenging due to factors like defect size, undercuts, and mucosal issues.

Conditions

  • Maxillary Obturators

Interventions

DEVICE

Maxillary Obturator

Maxillary obturators are prosthetic devices used to close maxillary defects resulting from surgical removal of part or all of the maxilla bone due to conditions like tumors or congenital anomalies. They separate the oral and nasal cavities, restore speech, swallowing, and mastication functions, provide facial support, and improve aesthetics and quality of life.
