Cleft lip and palate (CLP) is one of the most common congenital deformities with worldwide prevalence. It causes a range of issues for infants that mainly involve difficulty in feeding due to abnormal oronasal communication. For this purpose, feeding plates are provided to infants to act as an artificial palate to aid in feeding. The most crucial procedure in fabrication of a feeding plate is creation of the impression using the traditional finger technique or impression trays. This preliminary research aims to compare the effectiveness of novel impression trays with that of the traditional finger technique for recording impressions of infants with CLP.
This randomized controlled trial was conducted among 30 infants who were divided into two groups based on the method of obtaining impressions: Group I, finger technique; Group II, specialized acrylic tray (cleftray).
Use of cleftray required less impression time, a reduced amount of material, no incidence of cyanosis/choking in infants, and lower anxiety among doctors compared to the traditional method. Additionally, there was no distortion of cleft impressions, recorded maxillary tuberosity, or other fine details. Therefore, the novel impression tray (cleftray) exhibited superior outcomes in all the parameters compared to the finger technique.
Within the limitations of this study, we conclude that impression trays are superior to the traditional finger, spoon, or ice cream stick methods of creating impressions of CLP. However, it is necessary to conduct more clinical trials on a larger population based on other parameters to compare the effectiveness of the two techniques to draw definitive conclusions.
唇腭裂（CLP）是全球范围内最常见的先天性畸形之一。它给婴儿带来一系列问题，主要包括由于口鼻部连通异常导致的喂养困难。为此，会给婴儿提供喂食板，作为人工上颚来辅助喂养。制作喂食板最关键的步骤是使用传统手指技术或印模托盘制取印模。这项初步研究旨在比较新型印模托盘与传统手指技术在记录唇腭裂婴儿印模方面的有效性。
本随机对照试验在30名婴儿中进行，根据制取印模的方法将他们分为两组：第一组，手指技术组；第二组，特制丙烯酸托盘（腭裂托盘）组。
与传统方法相比，使用腭裂托盘所需的印模制取时间更短、材料用量更少，婴儿无发绀/窒息情况发生，医生的焦虑程度更低。此外，腭裂印模、记录的上颌结节或其他细微细节均无变形。因此，与手指技术相比，新型印模托盘（腭裂托盘）在所有参数上均表现出更好的效果。
在本研究的局限性范围内，我们得出结论，印模托盘优于传统的手指、勺子或冰棍棒制取唇腭裂印模的方法。然而，有必要基于其他参数在更大规模人群上进行更多临床试验，以比较这两种技术的有效性，从而得出明确结论。
