Immediate obturator stabilization (ISO) in severely atrophic edentulous maxilla: Suspension wiring technique

The treatment of malignant neoplasms of the hard palate comprises radical surgical resection. Defects of the maxillary sinus, hard palate and upper alveolar ridge may leave the patient with significant postoperative speech and swallowing problems [1]. Several maxillectomy defect classifications have been developed to ascertain the most effective means of rehabilitation for each type of defect. The defects can be repaired using fasciocutaneous or bone-containing free flaps or local advancement flaps [2]. A removable palatal obturator is a viable alternative when harvesting a flap is not feasible [3].
