While he was being fitted for complete dentures, the patient swallowed the central bearing plate that had become detached. The plate was lodged in the hypopharyngeal region of the pharynx and, with the patient under intravenous sedation, laryngoscope and biopsy forceps were used to retrieve it. Precautions that must be taken to prevent such occurrences include the proper attachment of the device components and testing for security, as well as upright positioning of the patient. The components should be explained to patients and they should be given instructions to eject immediately any part of the device that becomes dislodged.
在为患者安装全口义齿时，患者吞下了已脱落的中央承托板。承托板卡在咽部的下咽区域，在患者静脉镇静的情况下，使用喉镜和活检钳将其取出。为防止此类事件发生必须采取的预防措施包括正确连接装置部件并进行安全性测试，以及让患者保持直立姿势。应向患者解释部件情况，并告知他们如果装置的任何部分脱落，应立即吐出。
