三、正畸治疗特点Orthodontic treatment characteristics 高角病例和低角病例不仅在形态和功能上存在差 异, 对正畸治疗的反应也截然不同, 这可能与二者 下颌骨骨密度不同有关high-angle and low angle cases, thereare differences not only in the form and function, but laso in response to orthodontic treatment, there may be different in mineral content of the two mandibular bone.
高角病例下颌骨骨密度低, 对施加于牙齿上的 力量更敏感,牙齿移动速度较快High-angle cases ofmandibular bone mineral density is low, the force imposed on the teeth more sensitive, faster tooth movement;
低角病例下颌骨密度较高,对矫治力不敏感Thecases of jaw bone density of low-angle high, is not sensitive to the orthodontic force。
