OBJECTIVE
To describe and analyze the cephalometric dento-skeletal characteristics associated with Angle's Class II, division 1 malocclusion in Saudi population living in the western region.
MATERIALS AND METHODS
The material examined included 149 lateral head radiographs comprising two series: (1) 85 films of children with Class II, division 1 malocclusion and (2) 62 films of children with "normal" occlusion. Age range of the representing children was 10-13 years.
RESULTS
In Class II division 1 subjects, the maxilla was prognathic in relation to anterior cranial base. The mandible was normally positioned in relation to anterior cranial base. Upper incisors were proclined and lower incisors were normally positioned. The cranial base angle was not different between the two groups.
CONCLUSIONS
In the western region of Saudi Arabia, Class II division 1 malocclusion has specific characteristics. The presence of prognathic maxilla, in this sample, indicates that the use of head gear therapy might be more appropriate than functional appliances when treating Class II division 1 malocclusion in Saudis living in the Western region.
目的
描述并分析沙特阿拉伯西部地区居民安氏II类1分类错牙合畸形的头影测量牙-骨骼特征。
材料与方法
所检查的材料包括149张头颅侧位片，分为两个系列：（1）85张II类1分类错牙合畸形儿童的片子，（2）62张“正常”牙合儿童的片子。这些代表性儿童的年龄范围为10至13岁。
结果
在II类1分类受试者中，上颌相对于前颅底前突。下颌相对于前颅底位置正常。上切牙前倾，下切牙位置正常。两组之间颅底角无差异。
结论
在沙特阿拉伯西部地区，II类1分类错牙合畸形具有特定特征。在本样本中，上颌前突的存在表明，对于居住在西部地区的沙特人，在治疗II类1分类错牙合畸形时，使用头帽矫治器可能比功能性矫治器更合适。
