Abstract：
This study aimed to observe and analyze the effects of nasoalveolar molding (NAM) on maxillary arch dimensions in patients with bilateral complete cleft lip and palate (BCLP) using 3-dimensional analyses.
Retrospective case series.
Seventeen infants were treated using modified Khon Kaen University presurgical nasoalveolar molding devices (KKU-NAM). Dental casts were evaluated 3 dimensionally at 3 time points: pretreatment (T1), after using modified KKU-NAM for 2 weeks (T2), and before cheiloplasty (T3). Repeated-measures analysis of variance and Friedman test were used to compare the maxillary arch dimensions between time points.
Both sides of the cleft width, premaxilla deviation, and premaxilla protrusion had significantly reduced with the use of KKU-NAM. Premaxillary rotation had significantly improved, whereas the arch depth did not change significantly. Premaxilla width, posterior arch width, alveolar length, and height had significantly increased. The anterior arch width, intercanine width, and lateral sulcus width showed no significant changes. The intraclass correlation coefficient used to test the measurements indicated substantial reliability.
The modified KKU-NAM is an effective device for reducing the severity of bilateral cleft deformities, especially in the premaxilla area.

摘要：
本研究旨在通过三维分析观察和分析鼻肺泡成型（NAM）对双侧完全性唇腭裂（BCLP）患者上颌弓尺寸的影响。
回顾性病例系列。
17名婴儿使用改良的KhonKaen大学术前鼻肺泡成型装置（KKU-NAM）进行治疗。在3个时间点对牙模进行3维评估：预处理（T1），使用改良的KKU-NAM2周后（T2），和唇缘整修前（T3）。重复测量方差分析和弗里德曼检验用于比较时间点之间的上颌弓尺寸。
裂缝宽度的两侧，上颌前偏离,使用KKU-NAM后，上颌骨前突明显减少。上颌前旋转有明显改善，而足弓深度没有明显变化。上颌前宽度,后拱宽度,肺泡长度,身高有明显的增加。前弓宽度，犬齿间宽度,外侧沟宽度无明显变化。用于测试测量的组内相关系数表明了相当的可靠性。
改良的KKU-NAM是减轻双侧left裂畸形严重程度的有效装置，尤其是在上颌前区.
