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.
本研究旨在通过三维分析观察和分析鼻牙槽塑形（NAM）对双侧完全性唇腭裂（BCLP）患者上颌弓形态的影响。
回顾性病例系列研究。
17 名婴儿使用改良孔敬大学术前鼻牙槽塑形装置（KKU-NAM）治疗。牙模在 3 个时间点进行三维评估：治疗前（T1）、使用改良 KKU-NAM 治疗 2 周后（T2）和唇裂修复术前（T3）。采用重复测量方差分析和 Friedman 检验比较各时间点的上颌弓形态。
KKU-NAM 的使用使裂隙宽度、前颌骨偏斜和前颌骨突出两侧均显著减小。前颌骨旋转明显改善，而弓深度无明显变化。前颌骨宽度、后弓宽度、牙槽长度和高度显著增加。前弓宽度、犬齿间宽度和侧沟宽度无明显变化。用于测试测量值的组内相关系数表明其具有较高的可靠性。
改良 KKU-NAM 是一种有效减少双侧裂隙畸形严重程度的装置，尤其是在前颌骨区域。
