目的:为探讨打开成人前牙深覆的有效方法。方法:20例Ⅱ°、Ⅲ°前牙深覆患者使用方丝弓矫治器和平面导板联合进行治疗研究。结果:与单纯方丝弓矫治器相比,其打开咬合快且时间短,Ⅱ°深覆平均4.5个月,Ⅲ°深覆平均6.5个月。单纯方丝弓矫治打开咬合的时间为:Ⅱ°深覆平均6.8个月,Ⅲ°深覆平均9.5个月。两者有显著差异(P<0.05)。结论:方丝弓矫治结合平面导板联合矫治前牙深覆是一种非常有效的方法。
Objective: To explore an effective method to open the adult Antelopes. Methods: Twenty patients with deep Ⅱ, and ° anterior 覆 patients were treated with square arch appliance and flat guide plate. Results: Compared with the simple square wire appliance, the occlusal opening time was short, the average length of Ⅱ ° deep over 4.5 months and the depth of Ⅲ ° over 6.5 months. Simple square arch correction open bite time: Ⅱ 深 deep an average of 6.8 months, Ⅲ 深 deep an average of 9.5 months. There was a significant difference between the two (P <0.05). Conclusion: The treatment of square wire arch combined with flat guide plate in the treatment of anterior deep tufts is a very effective method.
