Individuals with cleft lip and palate have many anatomic and functional alterations compromising esthetics, hearing, speech, occlusion, and development/craniofacial growth. The rehabilitative treatment of these patients is very challenging and starts at birth aiming at the best treatment for all functional demands. This study aimed to evaluate the dimensional alterations of the dental arches of neonates with cleft lip and palate after two different primary surgical techniques.
The sample comprised 114 digital models of children aged from 3 to 36 months, with unilateral complete cleft lip and palate divided into two groups. Two different phases were evaluated: precheiloplasty and 1 year after palatoplasty. The evaluation was performed through the digital models of each child obtained by scanning digitalization (3D Scanner). Dental arches measurements were accomplished through Appliance Designer software. The following measurements were assessed: dental arch area, anterior amplitude of the cleft, total length of dental arch, intercanine distance, and intertuberosity distance. -test was applied to compare differences between groups.
No statistically significant differences were observed between groups at precheiloplasty phase. At 1 year after palatoplasty, the groups differed in the total length of dental arch ( = 0.002), with greater values for Group I.
This study suggests that the results of the different surgical techniques may alter the growth and development of the dental arches of neonates with cleft lip and palate.
唇腭裂患者存在许多解剖和功能改变,影响美观、听力、言语、咬合以及发育/颅面生长。这些患者的康复治疗极具挑战性,从出生就开始,旨在满足所有功能需求的最佳治疗。本研究旨在评估两种不同的一期手术技术对唇腭裂新生儿牙弓尺寸改变的影响。
样本包括114例年龄在3至36个月的儿童数字模型,这些儿童患有单侧完全性唇腭裂,分为两组。评估了两个不同阶段:唇裂修复术前和腭裂修复术后1年。通过扫描数字化(3D扫描仪)获得每个儿童的数字模型进行评估。通过矫治器设计软件完成牙弓测量。评估了以下测量指标:牙弓面积、裂隙前部宽度、牙弓总长度、尖牙间距离和结节间距离。采用t检验比较组间差异。
在唇裂修复术前阶段,两组之间未观察到统计学上的显著差异。在腭裂修复术后1年,两组在牙弓总长度方面存在差异(P = 0.002),第一组的值更大。
本研究表明,不同手术技术的结果可能会改变唇腭裂新生儿牙弓的生长发育。
