Objectives: The objectives of this study were to identify the mean anterior dentoalveolar dimensions of the Yemeni population, identifying possible gender differences and comparing maxillary and mandibular anterior dentoalveolar sizes across short-, average- and long-face groups. Materials and methods: This study comprised of taking cephalometric radiographs of 82 subjects (42 male, 40 female) with a mean age of 21.9 ± 2.8 years. The sample was divided into three groups: short-face group: FMA <25°; average-face group: FMA ≥25° to <30°, and long-face group: FMA ≥30°. Eight angular and seven linear measurements were taken and compared between the groups. Results: Significant gender differences between men and women were found in the mandibular dentoalveolar dimensions. In the short-face group, the maxillary upper dentoalveolar length and height was lower than the average-face group. Additionally, the ANB angle was the most pronounced parameter to be correlated with the anterior dentoalveolar dimensions, followed by FMA angle. Conclusion: The results of this study could act as a useful clinical instrument for orthodontic practice in Yemen. Understanding the association between sagittal and vertical relations with anterior dentoalveolar dimensions is essential in achieving optimal anteroposterior orthodontic tooth movement in cases with different sagittal and vertical jaw relationships.
