摘　　要：目的:观察基于三维(Three-dimensional,3D)打印技术的鼻-牙槽术前矫治器(Presurgical nasoalveolar molding,PNAM)对单侧完全性唇腭裂(Unilateral cleft lip and palate,UCLP)患儿鼻唇形态的矫治效果。方法:回顾性分析2020年5月-2023年5月成都市妇女儿童中心医院口腔科就诊的31例确诊为UCLP的患儿的临床资料,根据PNAM制作方式不同分为传统组(20例,采用传统方式制作PNAM)和3D组(11例,基于3D打印技术制作PNAM)。比较两组患儿正畸前后牙槽突裂隙宽度、鼻小柱斜度、鼻孔高度和鼻孔宽度,并随访正畸后3个月的手术效果。结果:两组患儿正畸后牙槽突裂隙宽度、鼻小柱斜度和鼻孔宽度均小于正畸前,鼻孔高度大于正畸前,且3D组上述指标均优于传统组,差异均有统计学意义(均P<0.05)。3D组患儿正畸后3个月的治疗优良率达100.00%(11/11)高于传统组的65.00%(13/20),差异有统计学意义(P<0.05)。结论:基于3D打印技术的PNAM对于UCLP患儿的鼻唇形态具有良好的矫正效果,可以缩窄牙槽突裂隙宽度和鼻孔宽度,延长鼻小柱高度,改善塌陷的形状,有利于降低手术难度,提高手术效果。Objective To observe the effect of presurgical nasoalveolar molding(PNAM)based on three-dimensional(3D)printing technology on nasolabial morphology correction in children with unilateral cleft lip and palate(UCLP).Methods The clinical data of 31 children diagnosed with UCLP who came to the department of stomatology Chengdu women and children's central hospital from May 2020 to May 2023 were retrospectively analyzed.According to different ways of making PNAM,children were divided into traditional group(20 cases,used to make PNAM in the traditional way)and 3D group(11 cases,used 3D printing technology to produce PNAM).The width of alveolar fissure,inclination of nasal column,nostril height and nostril width before and after orthodontic treatment were compared between 2 groups,and the results were followed up 3 months after orthodontic treatment.Results After orthodontic,the width of alveolar fissure,the inclination of nasal column and the width of nostril were lower than before orthodontic,and the height of nostril was higher than before orthodontic,and the above indexes in the 3D group were better than those in the traditional group,with statistical significance(P<0.05).3 months after orthodontic treatment,the excellent and good rate of surgical treatment in the 3D group was 100.00%(11/11)higher than that in the traditional group 65.00%(13/20),with statistical significance(P<0.05).Conclusion PNAM based on 3D printing technology has a good correction effect on the nasolabial morphology of children with UCLP,which can narrow the width of alveolar fissure and nostril width,lengthen the height of nasal column and improve the shape of collapse,which is conducive to reducing the difficulty of surgery and improving the surgical effect.
