Bone-borne rapid maxillary expansion distraction devices are used to achieve a more skeletal expansion and to avoid dental side effects of conventional expanders such as tipping of anchorage teeth. In this article, we report the use of a prefabricated expander fixed on 2 mini-implants in the anterior palate. This allows for the insertion of the mini-implants and the expander to occur without the need for an impression or any laboratory procedures. Especially when aligners are going to be used, the use of a mini-implant-borne expander seems to be reasonable because the expander can be left in place as a skeletal retainer during the aligner finishing.
骨支式上颌快速扩弓器用于实现更骨性的扩展，并避免传统扩弓器的牙齿副作用，如支抗牙倾斜。在本文中，我们报告了在前 palate 上使用固定在 2 个迷你种植体上的预制扩弓器。这允许在不需要印模或任何实验室程序的情况下插入迷你种植体和扩弓器。特别是在将要使用Aligner 时，使用迷你种植体支抗式扩弓器似乎是合理的，因为扩弓器可以作为骨骼保持器留在原位，直到Aligner 完成。
