Abstract
Aim: To evaluate the Bolton ratios in Brazilians with natural, normal occlusions.
Methods: Thirty-five dental casts of Brazilian Caucasians with a natural, normal occlusion from the files of the Postgraduate Program in Orthodontics of the Methodist University of São Paulo were scanned in three dimensions. On the scanned images, the greatest mesiodistal distance of each tooth from right first molar to left first molar was measured with Geomagic Studio 5 software. The Bolton ratios were then calculated.
Results: The anterior ratio amounted to 78.66% (SD ± 2.72) and the total ratio to 91.58% (SD ± 2.20).
Conclusion: The anterior, but not the overall, ratio was significantly different from the ratio suggested by Bolton.
目的:评价巴西人自然、正常闭塞的博尔顿比率。方法:对来自圣保罗卫理公会大学正畸研究生课程档案的35例自然正常咬合的巴西高加索人牙模进行三维扫描。在扫描图像上，用Geomagic Studio 5软件测量每颗牙齿从右第一磨牙到左第一磨牙的最大中远端距离。然后计算波顿比率。结果:前路比例为78.66% (SD±2.72)，总比例为91.58% (SD±2.20)。结论:前牙比例与Bolton建议的比例有显著性差异，而非整体比例。
