开发了一种用于牙齿运动的骨骼锚定系统。它由一个微型钛板组成，作为固定的锚点暂时植入上颌骨或下颌骨。在本文中，我们介绍了骨支抗系统侵入下磨牙的开合错，并评估了两个严重开合病例的治疗效果。在左、右两侧较少的第一、第二磨牙根尖区周围的颊皮质骨处固定微型钛板。弹性螺纹被用作正畸力的来源，以减少过高的磨牙高度。下磨牙内挤约3 ~ 5mm，开咬明显改善，几乎没有下门牙的挤压。正畸治疗期间未见严重副作用。该系统在正畸开咬矫正中对咬合平面的倾斜和水平控制也非常有效。
A skeletal anchorage system was developed for tooth movements. It consists of a titanium miniplate that is temporarily implanted in the maxilla or the mandible as an immobile anchorage. In this article, we introduce the skeletal anchorage system to intrude the lower molars in open-bite malocclusion and evaluate the results of treatment in two severe open-bite cases that underwent orthodontic treatment with the system. Titanium miniplates were fixed at the buccal cortical bone around the apical regions of the fewer first and second molars on both the right and left sides. Elastic threads were used as a source of orthodontic force to reduce excessive molar height. The lower molars were intruded about 3 to 5 mm, and open-bite was significantly improved with little if any extrusion of the lower incisors. No serious side-effects were observed during the orthodontic treatment. The system was also very effective for controlling the cant and level of the occlusal plane during orthodontic open-bite correction.
