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.
本研究针对8例因肿瘤切除而接受部分上颌骨切除术的患者进行。为每位患者制作了两种类型的阻塞器，一种是空心球型，另一种是颊侧翼缘型，采用了不同的印模技术。临床比较后得出结论，在舒适度、功能、语音和稳定性方面，无封闭空心部分的颊侧翼缘型阻塞器优于鼻侧封闭且尽可能延伸至缺损前部和外侧的空心球型阻塞器。
