Intraoral scanning is currently becoming the standard method for imaging the maxilla in patients with cleft lip and palate. However, the reliability of intraoral scans compared with traditional conventional impression methods has not yet been sufficiently described and examined in detail in newborns with severe types of cleft lip and palate.
The purpose of this clinical study was to assess the reliability and agreement between intraoral scanning and traditional impression methods for maxillary measurements in newborns with unilateral and bilateral cleft lip and palate (U/BCLP). A secondary aim was to evaluate the consistency of maxillary measurements obtained with and without general anesthesia.
Six newborns with cleft lip and palate underwent 4 maxillary impression methods (silicone impression and 3-dimensional (3D) scan, with and without anesthesia). Intra- and inter-observer reliability was assessed by 3 clinicians using intraclass correlation coefficient, median absolute deviation, and median relative deviation (α=.05).
The intraclass correlation coefficient values for both inter-observer and intra-observer reliability indicated excellent agreement (ICC>.90, P<.05) for maxillary dimension measurements. Acceptable variability was observed because of differences in reference point identification by clinicians and across data collection methods.
When assessing the maxilla in U/BCLP patients, both intraoral scanner and traditional impression techniques showed excellent reliability and agreement in measurements, whether performed while the newborns were awake or under general anesthesia.
口腔内扫描目前正成为唇腭裂患者上颌骨成像的标准方法。然而，与传统的传统印模方法相比，口腔内扫描的可靠性在严重唇腭裂类型的新生儿中尚未得到充分描述和详细研究。
本临床研究的目的是评估口腔内扫描与传统印模方法在单侧和双侧唇腭裂（U/BCLP）新生儿上颌骨测量中的可靠性和一致性。次要目的是评估在有和没有全身麻醉的情况下获得的上颌骨测量的一致性。
6例唇腭裂新生儿接受了4种上颌印模方法（硅橡胶印模和三维（3D）扫描，有和没有麻醉）。3名临床医生使用组内相关系数、中位数绝对偏差和中位数相对偏差评估观察者间和观察者内的可靠性（α=0.05）。
观察者间和观察者内可靠性的组内相关系数值表明，在上颌骨尺寸测量方面具有极好的一致性（ICC>0.90，P<0.05）。由于临床医生识别参考点的差异以及不同数据收集方法，观察到了可接受的变异性。
在评估U/BCLP患者的上颌骨时，无论是在新生儿清醒还是全身麻醉下进行，口腔内扫描仪和传统印模技术在测量方面均显示出极好的可靠性和一致性。
