作者主要研究支抗的矢状与垂直向的相互影响,并从牙周组织对矫治力的反应以及正畸力与咬合力相关性方面讨论支抗问题。 颅面发育 下颌生长过程中会发生位移和旋转。旋转取决于上颌复合体和髁状突的垂直向发育,如果髁状突垂直向生长超过上颌复合体和磨牙区牙槽骨的垂直向生长,下颌就向前旋转;如果髁状突垂直向生长比上颌生长慢,下颌就向后旋转,导致面部变长。 支抗在矢状和垂直方向的相互影响 在磨牙区一旦支抗发生垂直方向变化,就足以影响颅骨的关系。如
The author mainly studied the sagittal and vertical interaction of the anchors and discussed the problem of anchorage from the response of periodontal tissues to the orthodontic force and the relationship between orthodontic force and occlusal force. Craniofacial growth will occur during the growth of the mandibular displacement and rotation. The rotation depends on the vertical development of the maxillary complex and the condyle, and the mandible rotates forward if the condylar vertical growth exceeds the vertical growth of the alveolar bone in the maxillary complex and the molar. If the condylar process grows vertically Slower than maxillary growth, the lower jaw rotates backwards, causing the face to become longer. Support in the sagittal and vertical directions of the interaction in the molar area once the vertical deflection of the support, it is sufficient to affect the relationship between the skull. Such as
