| ［摘要］ 目的 探讨微种植体在安氏Ⅱ类1分类错（牙合）矫治中的应用效果，为临床推广使用微种植体提供理论依据。方法 选取安氏Ⅱ类1分类错（牙合）患者64例，其中男性32例，女性32例，年龄（22.78±3.26）岁。患者随机分为对照组和实验组，对照组采用口外J钩进行矫治，实验组采用微型种植体支抗进行矫治，治疗结束后，分析两组治疗前后头影和模型测量指标的变化。结果 头影测量结果显示两组矫治后的ANB、Ls-E、L1-NB、Li-E、UI-SN、U1-L1、U1-MP、U1-NA和SNA等指标较矫治前均显著减小（P<0.05或<0.01），而U6-PP较矫治前显著增大（P<0.05）；实验组矫治后的ANB、Ls-E、Li-E、UI-SN、U1-L1、U1-NA、U6-PP和SNA等指标均优于对照组（P<0.05）。对照组治疗疗程为（18±2）个月，实验组治疗疗程为（12±2）个月，实验组显著短于对照组（P<0.05）。两组矫治后覆盖（OJ）和覆（牙合）（OB）均较矫治前显著减小（P<0.01），实验组OJ和OB均优于对照组（P<0.05）。结论 微种植体能够有效矫治安氏Ⅱ类1分类错（牙合）。 |

| Abstract: |
| ［Abstract］ Objective To investigated the effect of micro-implant in the treatment of Angle Class Ⅱ division 1 classification and provide a theoretical basis for clinical promotion of the use of micro- implant.Methods Sixty-four patients with Angle Class Ⅱ Division 1 Malocclusion, 32women and 32 men，with average age of (22.78±3.26)years old, were randomly divided into control and experimental groups.In the control group,the patients treated with J hook,in the experimental group，the patients treated with micro-implant,before and after treatment, the change of cephalometric and model indexs were measured and analyzed.Results Two groups could take the correction of Angle Class Ⅱ division 1 malocclusion, but in the experimental group ANB Ls-E, U1-L1, U1-MP, U1-NA, U6-PP, the SNA indicators more well than those in the control group (P<0.05 or <0.01). The control group treatment course was (18±2)months, the experimental groups treatment course of (12±2)months, in the experimental group was significantly reduced treatment time(P<0.05). In the index of OJ and OB，the experimental group was better than the control group(P<0.01).Conclusion Micro-implant treatment could corrected Angle Class Ⅱ Division 1 Malocclusion well. |
