The introduction of mini-implants has broadened the range of tooth movements possible by fixed appliance therapy alone. The limits of fixed orthodontic treatment have become more a matter of facial appearance than anchorage. Many complex cases which would previously have required surgery or functional appliances can now be treated with fixed appliance therapy using mini-implants. A mutilated dentition case where mini-implants were used to provide anchorage for intrusion of molars and retraction of anterior teeth is reported here to illustrate this point.
微型种植体的引入拓宽了仅通过固定矫治器治疗所能实现的牙齿移动范围。固定正畸治疗的限制更多地体现在面部外观而非支抗方面。许多以前需要手术或功能性矫治器治疗的复杂病例,现在可以使用微型种植体通过固定矫治器治疗。本文报告了一个牙列缺损病例,其中使用微型种植体为磨牙压低和前牙内收提供支抗,以说明这一点。
