讨论了与牙列缺陷患者的正畸牙齿移动支抗相关的问题，并评估了文献中提出的各种解决方案，包括“种植体”、种植体和颧弓线。根据对干燥头骨骨质量的研究，提出了微型螺钉作为替代锚定，并讨论了可能的放置位置。演示了微型螺钉作为各种类型牙齿移动的锚固的应用。微型螺钉易于放置和拆卸，并且可以在插入后立即装载。然而，在扭转加载后稳定性受到限制。
The problems related to anchorage for orthodontic tooth movements in patients with deficient dentition are discussed, and various solutions suggested in the literature, including "onplants," implants, and zygoma wires, are evaluated. A miniscrew is presented as alternative anchorage, and possible locations for placement are discussed, based on studies of bone quality in dry skulls. Application of the miniscrew as anchorage for various types of tooth movement is demonstrated. Miniscrews are easily placed and removed and can be loaded immediately following insertion. However, stability is limited after loading with torsion.
