In the following study 20 adult skeletal open-bite patients were analysed after they had undergone dental compensation to camouflage the underlying skeletal discrepancy. The initial and final cephalometric records were analysed to determine the factors that led to the desired goal. The results showed no significant difference in the skeletal relationship. Molar intrusion was not recorded. The open-bite was correct mostly by reclining the upper incisors and by changing their position. Significant differences existed between the obtained results and the mechano-therapy employed. The geometrical model developed on the of the above makes it possible to predict and predetermine the targeted vertical dimension. Furthermore the results show extrusion of the front teeth as another dominant factor.
在以下研究中,对20名成年骨骼性开牙合患者进行了分析,这些患者在接受牙齿代偿以掩饰潜在的骨骼差异之后。分析初始和最终的头影测量记录,以确定达成预期目标的因素。结果显示骨骼关系无显著差异。未记录到磨牙压低情况。开牙合主要通过使上前牙舌倾并改变其位置得以矫正。所获结果与采用的机械治疗之间存在显著差异。基于上述情况建立的几何模型使得预测和预先确定目标垂直维度成为可能。此外,结果表明前牙伸长是另一个主要因素。
