UNLABELLED
Sound orthodontic movement of anterior teeth is delineated by the biological dimensions of the anterior alveolus.
OBJECTIVE
To establish and compare the anterior alveolar dimensions among normal and abnormal sagittal maxillomandibular relationships in a Saudi sample.
MATERIALS AND METHODS
The lateral cephalometric radiographs of 81 Saudi subjects (42 males and 39 females) were used to determine the anteroposterior and vertical dimensions of the anterior alveolus in Class I (N = 30), Class II (N = 24), and Class III (N = 27) cases. The anterior alveolar dimensions were then compared among males and females belonging to the same sagittal classification and between the different sagittal classifications of the same gender.
RESULTS
Significant differences (P < 0.05) in the anterior alveolar dimensions between males and females were demonstrated for the same sagittal jaw classification. Also, significant differences (P < 0.05) were detected between the anterior alveolar dimensions among the different sagittal maxillomandibular classifications of the same gender.
CONCLUSION
Both the gender and the sagittal maxillomandibular relationship can affect the anteroposterior and vertical dimensions of the anterior alveolus.
未标注
前牙的正常正畸移动由前牙槽的生物学尺寸界定。
目的
在沙特样本中确定并比较正常与异常矢状位上下颌关系中的前牙槽尺寸。
材料与方法
使用81名沙特受试者（42名男性和39名女性）的头颅侧位片，确定安氏Ⅰ类（N = 30）、安氏Ⅱ类（N = 24）和安氏Ⅲ类（N = 27）病例中前牙槽的前后向和垂直向尺寸。然后比较同一矢状位分类中的男性和女性之间以及同一性别不同矢状位分类之间的前牙槽尺寸。
结果
对于相同的矢状位颌骨分类，男性和女性之间的前牙槽尺寸存在显著差异（P < 0.05）。同样，在同一性别不同矢状位上下颌分类之间的前牙槽尺寸也检测到显著差异（P < 0.05）。
结论
性别和矢状位上下颌关系均可影响前牙槽的前后向和垂直向尺寸。
