目的:探讨上颌斜面导板配合直丝弓矫治器在Angle Ⅱ类2分类错中的矫治效果。方法:选取Angle Ⅱ类2分类患者12例,在不拔牙的情况下使用上颌斜面导板配合直丝弓矫治器对其矫治,治疗前后拍摄头颅侧位片进行X线头影测量分析。结果:所有患者在18±3个月完成治疗,治疗后下颌前移、建立了Ⅰ类磨牙关系,覆合覆盖正常,侧貌好。结论:上颌斜面导板配合直丝弓矫治对Angle Ⅱ类2分类错的非拔牙矫治疗效显著、疗程短。
Objective: To investigate the effect of maxillary incline guide combined with straight wire appliance in class Ⅱ division 2 malocclusion. Methods: Twelve patients with Angle Ⅱ class Ⅱ malocclusion were enrolled in this study. Maxillary incline guide plate was used in combination with straight wire appliance to treat orthodontics. Before and after treatment, the cephalometric films were measured by X - ray. Results: All the patients completed the treatment at 18 ± 3 months. After treatment, the mandibular movement progressed. The relationship between type Ⅰ molars was established. The coverage was normal and the appearance was good. Conclusion: The maxillary incline guide combined with straight wire arch correction has a significant effect on the treatment of Angle Ⅱ class Ⅱ malocclusion without extraction, and the treatment is short.
