Large clefts in the lip and palate are common congenital anomalies. If the cleft palate is large enough, conventional feeding techniques may not provide proper nutrition for the infant. Feeding obturators will aid in the ability of the infant to attain suction and help the infant to feed adequately. It is necessary for the infant to have sustained weight gain prior to surgery to correct the cleft lip and/or palate. Fabrication of an infant feeding obturator is a simple technique using materials found in every dental office. An impression is made using modeling plastic impression compound. This impression is relined using irreversible hydrocolloid, and the resulting cast is used to enable a vacuum-formed obturator to be fabricated. The vacuum-formed obturator is smoothed and adjusted in the infant's mouth to ensure closure of the palate but allows pace posteriorly to allow normal breathing. The resulting obturator is well retained in the infant's mouth, allowing feeding.
唇腭裂是常见的先天性畸形。如果腭裂足够大，传统的喂养技术可能无法为婴儿提供足够的营养。喂养阻塞器有助于婴儿获得吸力，帮助婴儿充分进食。在进行唇裂和/或腭裂修复手术之前，婴儿有必要持续体重增加。制作婴儿喂养阻塞器是一种简单的技术，使用每个牙科诊所都能找到的材料。使用模型塑料印模膏制作印模。用不可逆水胶体对该印模进行重衬，然后用所得的模型制作真空成型的阻塞器。在婴儿口腔中对真空成型的阻塞器进行打磨和调整，以确保腭部闭合，但后部要留出空间以保证正常呼吸。所得的阻塞器能很好地固定在婴儿口腔中，便于喂养。
