This study aimed to evaluate the three-dimensional changes in maxillary alveolar morphology after using modified NAM in patients with complete unilateral cleft lip and palate.
This is a retrospective study.
The study was carried out in the dental hospital, Faculty of Dentistry of Naresuan University, Phitsanulok, which serves as a tertiary care center.
The population sample consisted of 19 patients with nonsyndromic complete unilateral cleft lip and palate.
All patients received the modified NAM treatment based on the treatment protocol of the Naresuan University Cleft and Craniofacial Center, Thailand.
Dental models obtained at pre-treatment (T0) and post-treatment (T1) were scanned to construct the digital models. The maxillary digital models that showed dimensional changes between T0 and T1 were measured using a computer graphic software.
The modified NAM resulted in a significant decrease in the anterior cleft width, posterior cleft width, and anterior arch width. Conversely, it caused a significant increase in the length of the lesser cleft segment and the greater segment rotation. However, the change in the height of both segments and posterior arch width was not found to be significant.
The modified NAM was an effective device for reducing the alveolar cleft width while improving the alignment of alveolar cleft segments.
本研究旨在评估改良 NAM 在单侧完全性唇腭裂患者中的应用对上颌牙槽骨形态的三维变化。
这是一项回顾性研究。
该研究在泰国纳瑞宣大学牙科学院的牙科医院进行，该医院是一家三级护理中心。
研究人群包括 19 名非综合征性单侧完全性唇腭裂患者。
所有患者均根据泰国纳瑞宣大学腭裂颅面中心的治疗方案接受改良 NAM 治疗。
在治疗前（T0）和治疗后（T1）获取的牙模进行扫描以构建数字模型。使用计算机图形软件测量 T0 和 T1 之间显示尺寸变化的上颌数字模型。
改良 NAM 可显著减小前裂隙宽度、后裂隙宽度和前弓宽度。相反，它导致小裂隙段和大段旋转的长度显著增加。然而，两段和后弓宽度的高度变化并不显著。
改良 NAM 是一种有效减少牙槽裂宽度同时改善牙槽裂段排列的装置。
