Obturator prostheses are used to improve mastication, speech, and swallowing by reestablishing oronasal separation and aesthetics in maxillary defect patients. A sectional and magnetically retained functional removable speech bulb prosthesis was planned to treat the congenitally cleft hard and soft palates of this patient. The obturator part, localized into lateral nasal undercuts covered with sound mucosa, was used to retain the complete denture. Two pieces of the prosthesis were joined together by a magnet in the mouth. A special hinge mechanism was added to join the complete denture and functional velopharyngeal parts of the prosthesis for the treatment of velopharyngeal inadequacy. Sufficient retention was obtained, and no major complications were seen in the patient's prosthesis in periodic controls.
闭孔义齿用于通过重建上颌骨缺损患者的口鼻分隔和美观来改善咀嚼、言语和吞咽功能。计划制作一种分段式且通过磁力固位的功能性可摘语音球义齿，以治疗该患者先天性软硬腭裂。闭孔部分位于覆盖有健康黏膜的鼻侧倒凹内，用于固位全口义齿。义齿的两部分在口腔内通过一块磁体连接在一起。添加了一种特殊的铰链机制，将全口义齿与义齿的功能性腭咽部分连接起来，用于治疗腭咽闭合不全。获得了足够的固位力，在定期检查中患者的义齿未出现重大并发症。
