摘要
目的:评价OPA-K直丝弓矫治器治疗安氏Ⅲ类错的临床疗效,并探讨其机制和使用方法。方法:临床选择14～23岁安氏Ⅲ类错患者16例,应用OPA-K直丝弓矫治器进行治疗,并对治疗前后X线头影测量值的变化进行分析。结果:矢状方向上,SNA和ANB分别增加1.36°和1.32°,差异均具有统计学意义(P<0.05),SNB的变化无显著性(P>0.05)。U1-NA和U1-SN分别增加4.77°和13.05°,U1-NA(mm)增加3.13mm,L1-NB和L1-MP分别减小6.12°和6.68°,L1-NB(mm)减小2.22mm,以上差异均具有统计学意义(P<0.05)。垂直方向上,MP和Y轴的变化SN-均无显著性(P>0.05)。结论:应用OPA-K直丝弓矫治器治疗安氏Ⅲ类错可取得令人满意的临床效果,是适合东方人(中国人)错畸形治疗的直丝弓矫治器。
Objective：To evaluate the effects of the Oriental Preadjusted Appliance-KOSAKA applied in Angle class Ⅲ malocclusion and discuss the mechanism and application. Method：16 cases aged 14～23 years old with Angle class Ⅲ malocclusion were chosen and treated with the Oriental Preadjusted Appliance-KOSAKA. Cephalometric analysis was performed before and after the treatment. Result：In the sagittal direction,SNA and ANB were increased 1.36° and 1.32°,there were significant differences in these changes（P〈0.05）.but the changes of SNB were no significant（P〉0.05）. U1-NA and U1-SN were increased 4.77° and 13.05°,U1-NA（mm） were increased 3.13 mm,L1-NB and L1-MP were reduced 6.12° and 6.68°,L1-NB（mm） were reduced 2.22 mm,there were significant differences in these changes（P〈0.05）. In the vertical direction,the changes of SN-MP and Y axis were no significant（P〉0.05）. Conclusion：The Oriental Preadjusted Appliance-KOSAKA is effective for Angle class Ⅲ malocclusion and suitable for Oriental（Chinese）.
