The most frequent openings of the maxilla result from cleft palates or tumors that require either partial or total surgical removal of the palate. Intraoral defects in the maxilla can cause an opening into the nasopharynx complex. Cleft palates or surgically removed tumors can have a devastating effect on a patient's appearance and speech. Obturators allow patients to eat and drink without fear of food or drink entering the oronasal and/or oroantral cavities during mastication. This article reviews the three clinical situations in which obturators are used to correct intraoral defects and discusses a clinical case that was treated successfully by using an obturator. An alternative method for fabricating a hollow bulb obturator also is discussed.
上颌骨最常见的开口是由腭裂或需要部分或全部手术切除腭部的肿瘤引起的。上颌骨的口腔内缺损可导致通向鼻咽复合体的开口。腭裂或手术切除的肿瘤会对患者的外貌和言语产生毁灭性影响。阻塞器可使患者在咀嚼时进食和饮水而不必担心食物或饮料进入口鼻和/或口窦腔。本文回顾了使用阻塞器纠正口腔内缺损的三种临床情况，并讨论了一例使用阻塞器成功治疗的临床病例。还讨论了一种制造空心球阻塞器的替代方法。
