To enable investigation of palatal changes in infants who are prematurely born, it is necessary to first establish a reliable method of measurement of these tiny edentulous palates. This study compared the Olivetti-Inspector machine, Vernier calipers, and stereophotogrammetry for this purpose. Measurements were taken of 12 palatal casts of four infants at prescribed time intervals during the neonatal period. In each of the three methods, measurements were recorded as variables generated in the X and Z axes of the Cartesian scale in relation to three specified points along the Y axis. The results revealed that all methods were comparable, but the Vernier calipers differed significantly from the other two methods in height measurements, (p < 0.001). It was also found that both the Olivetti-Inspector machine and the Vernier calipers consistently underestimated the width, compared with Olivetti-Inspector machine, (p < 0.05). Stereophotogrammetry was found to be the most consistent method of measuring the configuration of preterm infant palates.
为了能够对早产婴儿的腭部变化进行研究，首先有必要建立一种可靠的方法来测量这些无牙的小腭部。本研究为此比较了Olivetti-Inspector机器、游标卡尺和立体摄影测量法。在新生儿期，按照规定的时间间隔对4名婴儿的12个腭模型进行了测量。在这三种方法中，测量结果均记录为笛卡尔坐标系X轴和Z轴上相对于沿Y轴的三个指定点所产生的变量。结果显示，所有方法都具有可比性，但游标卡尺在高度测量方面与其他两种方法有显著差异（p < 0.001）。还发现，与Olivetti-Inspector机器相比，Olivetti-Inspector机器和游标卡尺都始终低估了宽度（p < 0.05）。立体摄影测量法被认为是测量早产婴儿腭部形态最一致的方法。
