[摘要]目的 比较J钩支抗与种植体支抗应用于矫治安氏Ⅰ类双颌前突畸形的应用效果。方法 选取2017年1～10月我院收治的80例安氏Ⅰ类双颌前突畸形患者作为研究对象，采用随机数字表法将其分为A组(J钩支抗)和B组(种植体支抗)，每组各40例。比较两组患者的矫治周期及牙相关指标。结果 B组患者的平均矫正周期短于A组，差异有统计学意义(P<0.05)。矫治后，B组患者的上颌磨牙抗力中心-腭平面距(U6C-PP)、鼻唇角(Cm-Sn-UL)水平高于A组，上唇突点-RL距(UL-RL)水平低于A组，差异有统计学意义(P<0.05)。结论 与J钩支抗相比，采用种植体支抗方法矫治安氏Ⅰ类双颌前突畸形的周期更短，矫治效果更好。
