摘　　要：目的:探讨平面导板或斜面导板在直丝弓矫治技术治疗AngleⅡ低角型错中的应用。方法:选取AngleⅡ低角型错畸形患者20例为研究对象,采用上颌平面导板或斜面导板与直丝弓矫治技术相结合的治疗方法,比较治疗前后X线头影测量的变化。结果:矢状方向上,下颌骨位置前移,SNB、ANB、L6-Ptm明显改善;垂直方向上,MP-SN、MP-FH、L6-MP明显增加,差异均有统计学意义(P<0.05)。结论:AngleⅡ低角型错畸形治疗中,采用上颌平面导板或斜面导板与直丝弓矫治技术相结合的治疗方法,可获得满意的面部下1/3外形,有利合关系纠正,并缩短矫治疗程。Objective： To evaluate the application of the fiat bite plate or incline bite plate combined with straight arch wire technique in the treatment of Angle Class H malocclusion with low-angle.Method： 20 cases of low-angle class Ⅱ malocclusion were treated with flat bite plate or incline bite plate combined with straight arch wire technique. The changes of cephalometrics were compared between before and after the treatment. Result： On the sagittal direction, the mandible moved forward; SNB, ANB and L6-Ptm were significantly improved. On the vertical direction, MP-SN, NP-FH and L6-Ptm were significantly improved. Conclusion： Using flat bite plate or incline bite plate combined with straight arch wire technique in treating Angle Class Ⅱ malocclusion with low-angle can result in a satisfactory appearance in the lower one third of the face, correct the dental occlusion, and shorten the course of treatment.
