PURPOSE
To determine differences between open bite and normal vertical overbite regarding distribution, size and clinical appearance of palatal rugae, depth and length of the palate, intercanine and intermolar widths and arch perimeter.
METHODS
A cross-sectional study was performed in 264 superior models were studied with a 3D analysis system. A total of 132 individuals with AOB and 132 individuals with normal vertical overbite were evaluated, chosen from public schools with ages between 8 and 16 years. Palatal anthropometric features were evaluated. Qualitative analysis of palatal rugae was performed, exploring the shape, direction, unification and sensitivity of the palate. The Mann Whitney and Chi Square tests were used for statistical analyses.
RESULTS
The average age was 11.37 ± 2.27 years for normal overbite and 11.87 for anterior open bite, with 54.9% of women. No significant differences were found between subjects with AOB and subjects with normal vertical overbite regarding intermolar or intercanine width. The maxillary length and depth and the height and width of palatal rugae were lower in the AOB group. The most common rugae shapes were curved and wavy, predominating in the horizontal direction with a parallel distribution.
CONCLUSION
Qualitative evaluation demonstrated asymmetry in the shape, direction and unification of rugae in both groups. Most arch measurements were greater in individuals with AOB.
目的
确定开颌与正常垂直覆颌在腭皱襞的分布、大小和临床表现、腭部深度和长度、尖牙间及磨牙间宽度以及牙弓周长方面的差异。
方法
进行一项横断面研究，对264个上颌模型使用三维分析系统进行研究。从公立学校中选取了132名开颌个体和132名具有正常垂直覆颌的个体进行评估，年龄在8至16岁之间。对腭部人体测量特征进行评估。对腭皱襞进行定性分析，探究腭部的形状、方向、融合情况和敏感性。采用曼-惠特尼检验和卡方检验进行统计分析。
结果
正常覆颌组的平均年龄为11.37±2.27岁，前牙开颌组为11.87岁，女性占54.9%。在磨牙间或尖牙间宽度方面，开颌组与正常垂直覆颌组之间未发现显著差异。开颌组的上颌长度、深度以及腭皱襞的高度和宽度较低。最常见的皱襞形状为弯曲和波浪状，在水平方向占主导且呈平行分布。
结论
定性评估表明两组在皱襞的形状、方向和融合方面存在不对称。大多数牙弓测量值在开颌个体中更大。
