Abstract

The aim of this study was to observe the clinical and cephalometric effects of intra-oral distalization with the maxillary bimetric arches. 3 girls and 1 boy with a mean age of 13.5 years with Class II skeletal and dental relationship were selected. Care was taken to select patients having a normal vertical growth pattern. Lateral cephalograms were taken at the beginning and at the end of the distalization period, which was approximately 3 months. To observe the distal movement, a metal marker was attached to the distal end of the buccal tube of the first molar. On each lateral cephalometric radiograph a reference plane perpendicular to the occlusal plane and passing through the point Sella was drawn to assess the amount of distalization. Cephalometric measurements indicated that the upper molars moved approximately 3 mm distally and that the lower incisors were proclined.

磨牙远端具有对称的磨牙远端弓。
本研究的目的是观察上颌双足弓口腔内远端术的临床和头侧测量效果。选择3名女孩和1名男孩,平均年龄13.5岁,骨骼和牙齿关系II级。注意选择具有正常垂直生长模式的患者。在远端期的开始和结束时分别拍摄侧位脑电图,远端期约为3个月。在第一磨牙颊管远端附着金属标记,观察其远端运动。在每个侧位头颅x线片上绘制一个垂直于咬合平面并穿过Sella点的参考平面,以评估远距的量。头颅测量显示上磨牙向远端移动约3mm,下门牙前倾。
