Results The height of anterior and posterior alveolar, ANB angle, anterior axis of central incisors, and the Go-Gn linear measurement for the patients under 16 years old showed significant differences before and after treatment. 结果患者上下颌骨关系明显改善,前牙牙槽高度、后牙牙槽高度、ANB角、上下中切牙轴角及16岁以下患者下颌体长度矫治前后有显著性差异。
Result: The length of retromolar space, the length of the mandibular alveolar ridge and the mesiodistal crown width of mandibular third molar were related to the impaction of mandibular third molar, but the gonial angle, the crystal-marginal angle were not. 结果:磨牙后间隙长度、下颌骨牙槽长度和第三磨牙牙冠宽度与第三磨牙阻生相关,下颌角和嵴缘夹角角度与阻生牙无关。
The Chinese dry crania ( 180) were studied by measuring the total prognathism, the middle prognathism and the alveolar profile angle. 本文测量了180例干燥颅骨的总面角、鼻面角和齿槽面角三项角度项目;
