| ［摘要］ 目的 测量骨性安氏Ⅱ类错（牙合）畸形患者经拔牙或非拔牙矫治后的牙（牙合）特征，以评价其临床治疗效果。方法 应用PAR指数分别对采用拔牙或非拔牙矫治的两组青少年骨性安氏Ⅱ类错（牙合）畸形患者（均21例）矫治后的牙模型进行定量测量,分析比较两组治疗后牙（牙合）特征的差异。结果 矫治后，拔牙组权重PAR总分为（0.62±0.74），非拔牙组为（0.90±1.37），差异无统计学意义(P>0.05)。其他PAR各分值两组均较低，差异亦无统计学意义(P>0.05)。结论 青少年骨性安氏Ⅱ类错（牙合）畸形经拔牙与非拔牙矫治后，从牙（牙合）特征方面评价均取得了满意的疗效。 |

| Abstract: |
| ［Abstract］ Objective To evaluate the outcome of the patients with skeletal class Ⅱ malocclusions treated by extraction or non-extraction through the occlusions assessing.Methods The post-treatment dental casts of two groups of adolescence patients with skeletal class Ⅱ malocclusions treated by extraction or non-extraction respectively were collected. The PAR index were measured on dental casts quantitatively. The PAR score were analyzed to compare the dental-occlusion difference between the two groups.Results After treatment, the weighted overall PAR scores was （0.62±0.74） in extraction group and （0.90±1.37） in non-extraction group and there was no significantly different between two groups(P>0.05).The other PAR scores were all low and showed no statistical differences between two groups(P>0.05).Conclusion Evaluating from the dental-occlusion,both extraction and non-extraction treatment can achieve successful results. |
