There are various types of obturator fabrication achievable by prosthodontist. Maxillectomy, which is a term used by head and neck surgeons and prosthodontists to describe the partial or total removal of the maxilla in patients suffering from benign or malignant neoplasms is a defect for which to provide an effective obturator is a difficult task for the maxillofacial prosthodontist. Multidisciplinary treatment planning is essential to achieve adequate retention and function for the prosthesis. Speech is often unintelligible as a result of the marked defects in articulation and nasal resonance. This paper describes how to achieve the goal for esthetics and phonetics and also describes the fabrication of a hollow obturator by two piece method, which is simple and maybe used as definitive obturator for maximum comfort of the patient.
口腔修复医生可以制作出多种类型的阻塞器。上颌骨切除术是头颈外科医生和口腔修复医生用来描述患有良性或恶性肿瘤的患者上颌骨部分或全部切除的术语，对于颌面修复医生来说，为这种缺损提供有效的阻塞器是一项艰巨的任务。多学科治疗计划对于实现假体的充分固位和功能至关重要。由于发音和鼻腔共鸣存在明显缺陷，语音通常难以理解。本文描述了如何实现美学和语音目标，还描述了通过两件式方法制作中空阻塞器的过程，这种方法简单，可作为确定性阻塞器，以使患者获得最大程度的舒适感。
