Open bite treatment with microscrew implant anchorage is discussed in relation to vertical control of the posterior dentoalvelar dimension. Maxillary microscrew implants provided anchorage for intruding the posterior teeth and retracting the anterior teeth; mandibular microscrew implants were used to apply intrusion force distal to the mandibular first molars to prevent mesial tipping of the posterior teeth during space closure. Closing the mandibular plane after intruding the maxillary posterior teeth and bodily mesial movement of the mandibular posterior teeth contributed to facial profile improvement. The efficacy and potency of microscrew implants in open bite treatment are discussed.
本文讨论了使用微螺钉种植体支抗进行开牙合治疗与后牙牙槽垂直维度控制的关系。上颌微螺钉种植体为压低后牙和内收前牙提供支抗；下颌微螺钉种植体用于在下颌第一磨牙远中施加压低力，以防止在关闭间隙过程中后牙近中倾斜。在上颌后牙压低后关闭下颌平面以及下颌后牙整体近中移动有助于改善面部轮廓。文中还讨论了微螺钉种植体在开牙合治疗中的疗效和效能。
