Abstract: (498 Views)
Maxillary defects occur for various reasons, such as congenital malformations, cancer, pathological changes, radiation burns or surgical interventions. Patients with large defects, progressive disease and those undergoing post-operative chemotherapy or radiotherapy must be rehabilitated by obturator prostheses. Making a well-extended impression for obturator prostheses may be difficult in the case of massive defects. This article presents a method for making impressions of massive maxillary defects using a special tray with a wide opening in the palatal region. |
