目的:比较种植体支抗和J钩支抗矫正安氏II类1分类患者内收前牙的有效性和安全性。方法:32例青年女性安氏II类1分类错患者随机分为两组。种植体支抗组和J钩支抗组。结果:J钩支抗组患者治疗前后U6-PTV差值为1.8±2.43mm,U1-NA°差值为(-4.4±3.79)°,U1-NA差值为(-2.6±2.04)mm,种植体支抗组患者治疗前后U6-PTV差值为1.9±3.36mm,U1-NA°差值为(-10.4±3.93)°,U1-NA为(-2.2±2.08)mm,两组患者U6-PTV差值和U1-NA差值的差异均无统计学意义(P>0.05),U1-NA°差值的差异有统计学意义(P<0.05)。结论:J钩支抗和种植体支抗技术均具有较好的正畸疗效,且种植体支抗技术具有支抗稳定性高,舒适性强,生物相容性好,不依赖于患者等优点。
OBJECTIVE: To compare the efficacy and safety of implant support and J hook support in the treatment of adduction anterior Class II and Class 1 patients. Methods: Thirty-two young women with Class II-1 malpractice were randomly divided into two groups. Implant support group and J hook support group. Results: The difference of U6-PTV before and after treatment in patients with J-hook support was 1.8 ± 2.43mm, the difference of U1-NA was (-4.4 ± 3.79) °, the difference of U1-NA was (-2.6 ± 2.04) The difference of U6-PTV before and after treatment in implant support group was 1.9 ± 3.36mm, the difference of U1-NA ° was (-10.4 ± 3.93) °, U1-NA was (-2.2 ± 2.08) mm, U6 -PTV difference and U1-NA difference was not statistically significant (P> 0.05), U1-NA ° difference was statistically significant (P <0.05). CONCLUSION: Both J-hook and implant support techniques have good orthodontic efficacy, and implant anchorage has the advantages of high stability, good comfort, good biocompatibility and independence from patients .
