摘　　要：目的:评价Frog磨牙远移器在治疗安氏Ⅱ类1分类牙源性错牙合畸形时的临床疗效。方法:对15例安氏Ⅱ类1分类错牙合伴上颌牙列轻中度拥挤的病例,用Frog磨牙远移器推磨牙向远中,并配合直丝弓固定矫治器进行不拔牙矫治,结合X线头影测量,评价Frog磨牙远移器的治疗效果。采用SPSSl3.0统计学软件进行配对t检验。结果:U6-Ptm(mm)、U6-PTV(mm)分别平均减少2.20mm(P<0.01),2.81mm(P<0.01),具有显著性差异,表明上颌第一磨牙明显向远中移动,同时U6-SN(°)减少2.53°(P>0.05),无显著性差异,表明上颌第一磨牙无远中向倾斜。即上颌第一磨牙发生了远中向的整体移动。结论:Frog磨牙远移器可实现磨牙整体远移,是不拔牙矫治安氏Ⅱ类1分类错牙合伴上颌牙列轻中度拥挤的有效方法之一,简便、有效且不受患者依从性的影响。Objective To evaluate the clinical efficacy of Frog Molar Distalization Appliance on Angle class Ⅱ division 1 malocclusion treatment. Methods 15 cases of Angle class Ⅱ division 1 malocclusion whose maxillary dentitions were mild or moderate crowded were treated with Frog Molar Distalization Appliance and straight wire fixed appliance to achieve non -extraction treatment. Cephalometric radiographs were taken and analyzed before and after the treatment.SPSS 13.0 software package was used for paired-samples t test. Results The average reductions of U6-Ptm （mm） and U6 -PTV （mm） were 2.20mm （P 0.01）,2.81 mm （P 0.01）with significant differences, indicating that the maxillary first molars had moved to the distal obviously.While the reduction of U6- SN （°） was 2.53 °（P 0.05） with no significant difference,indicating that the maxillary first molars had no distal tilt.That was the maxillary first molars moved to the distal as a whole. Conclusion The Application of Frog Molar Distalization Appliance for maxillary molar distalization is one of the good methods to correct Angle class Ⅱ division 1 malocclusion with maxillary dentition mild or moderate crowded.It is simple,effective and not impacted by patient compliance.
