To propose an alternate, r eliable, and easy-to-use functional swallow method for establishing the posterior palatal seal.
Accurate r egistration of the posterior palatal seal is crucial to the success of the maxillary complete denture. The conventionally used functional "Ah" technique may not be r eliable at times to record the posterior palatal seal, hence compromising the retention of the maxillary complete denture. Case description and technique: A 70-year-old female patient requiring complete dentures presented with an unusually tense soft palate during the phase of posterior palatal seal development. The soft palate did not relax and remained in a superior position when the "Ah" functional method was used to record the seal. The posterior palatal seal area could not be compressed sufficiently during border molding, preventing the formation of an adequate seal. Hence, a new functional technique was devised to relax and displace the soft palate for developing an effective seal. This case report describes a novel and reliable method of displacing the posterior palatal seal area with a low-fusing compound by utilizing the patient's functional swallow position.
The functional swallow method can be used effectively as an alternative and reliable method to obtain a consistent posterior palatal seal.
The functional swallow method of developing the posterior palatal seal is simple, less demanding on the clinician, and can save chairside time. It also helps in an easy transfer of the demarcated posterior palatal seal area to the custom tray. The method lets the dentist be in charge of developing the seal rather than relying on the arbitrary cast scrapping by the technician. Also, the seal can be achieved by employing commonly used materials.
提出一种替代的、可靠的、易于使用的功能吞咽方法，以建立后腭 seal。
准确记录后腭 seal 是上颌全口义齿成功的关键。传统上使用的功能“啊”技术有时可能不可靠，无法记录后腭 seal，从而影响上颌全口义齿的固位。
一位 70 岁的女性患者需要全口义齿，在开发后腭 seal 时，她的软腭异常紧张。当使用“啊”功能方法记录 seal 时，软腭不会放松，仍然处于高位。在边缘成型过程中，后腭 seal 区域无法充分压缩，无法形成足够的 seal。因此，设计了一种新的功能技术，以放松和移位软腭，以形成有效的 seal。本病例报告描述了一种新颖且可靠的方法，即利用患者的功能吞咽位置，通过使用低熔化合物来移位后腭 seal 区域。
功能吞咽法可作为一种替代方法，用于获得一致的后腭 seal，方法可靠。
开发后腭 seal 的功能吞咽方法简单，对临床医生的要求不高，可以节省椅旁时间。它还可以帮助将标记的后腭 seal 区域轻松转移到定制托盘上。该方法让牙医负责开发 seal，而不是依赖于技术人员随意刮除模型。此外，还可以使用常用材料来实现 seal。
