To determine the main mandibular dental arch forms, 278 dental casts of untreated French adults with normal occlusions were examined. Six measurements of the mandibular dental arches were performed, and five independent ratios were determined. By following the k-means clustering method on the basis of these ratios and the use of polynomial functions of the sixth degree, five mandibular dental arch forms were defined, and an arch guide was developed. The proposed forms are relatively narrow in comparison with previous studies. No significant differences in their distributions were seen between male and female subjects. However, the dental arches of the women have smaller dimensions.
为确定下颌牙弓的主要形态，对278例未经治疗、咬合正常的法国成年人的牙模进行了检查。对下颌牙弓进行了六项测量，并确定了五个独立的比率。基于这些比率采用k均值聚类法并使用六次多项式函数，定义了五种下颌牙弓形态，并开发了一种牙弓指南。与先前的研究相比，所提出的形态相对较窄。男性和女性受试者在其分布上未见显著差异。然而，女性的牙弓尺寸较小。
