The mechanism of bite plane was to raise the posterior teeth ( 1.1mm) and to lower the anterior teeth ( 0.8mm). 其作用机制是使后牙升高(1.1mm),下前牙压低(0.8mm)。
The results showed that bite plane can correct deep overbite rapidly ( within 6 months) and effectively. 结果发现:平面导板能迅速(6个月)有效矫治深覆牙合;
Methods Choose 12 patients whose deep bite of anterior teeth reaching ⅱ~ⅲ degree. Open up bite helped by maxilla plane plate before correcting, in correcting and after failing in opening up bite by Edgewise appliance. 方法选择12例前牙深覆牙合达Ⅱ~Ⅲ度的患者,分别在矫治前、矫治中及方丝弓矫治器打开咬牙合失败后,用上颌平面导板协助打开咬合。
