[Clinical comparison of different types of obturators constructed after maxillary resections].

This investigation was carried on eight patients who had undergone partial maxillary resection for the eradication of tumors. Two types of obturators, one being hollow-bulb and the other buccal flange were constructed for each patient, using different impression techniques. When these were compared clinically, it was concluded that buccal flange obturators which were constructed without closed hollow sections were superior to the hollow-bulb obturators with closed nasal sections extending as far as possible into the anterior and lateral aspects of the defect, in comfort, function, speech and stabilization.
