本研究对30名正常人在颌面测定铰链轴与切点间的位置关系,对200副装到简单(牙合)架上的石膏牙列模型测定(牙合)架旋转轴与切点间的位置关系,然后用几何方法分析了在测得数据条件下,假设以(牙合)架开闭方法增加3mm垂直距离时,在制作的上颌修复体(牙合)接触关系上可能导致的误差。从而阐明了不合理使用简单(牙合)架的后果及解决方法。 In this study, 30 normal people in the maxillofacial determination of hinge axis and the relationship between the tangent point, the 200 mounted to the simple (occlusal) gypsum dentition model column determination (occlusal) frame rotation axis and the tangent point Then, the geometric errors of the maxillary restorations may be analyzed by geometric methods under the condition of the measured data, assuming that the 3 mm vertical distance is increased by the occlusal opening and closing method . Thus clarifying the consequences of unreasonable use of a simple (occlusal) stent and solutions.
