Compare the traditional method of mounting dental casts on a semiadjustable articulator and the new method suggested by Wolford and Galiano, 1 analyzing the inclination of maxillary occlusal plane in relation to FHP.
Two casts of 10 patients were obtained. One of them was used for mounting of models on a traditional articulator, by using a face bow transfer system and the other one was used to mounting models at Occlusal Plane Indicator platform (OPI), using the SAM articulator. After that, na analysis of the accuracy of mounting models was performed. The angle made by de occlusal plane and FHP on the cephalogram should be equal the angle between the occlusal plane and the upper member of the articulator.
The measures were tabulated in Microsoft Excell(®) and calculated using a 1-way analysis variance. Statistically, the results did not reveal significant differences among the measures.
OPI and face bow presents similar results but more studies are needed to verify its accuracy relative to the maxillary cant in OPI or develop new techniques able to solve the disadvantages of each technique.
比较在半可调式牙合架上安装牙模的传统方法与Wolford和Galiano提出的新方法，分析上颌牙合平面相对于Frankfort水平平面（FHP）的倾斜度。
获取10名患者的两组牙模。其中一组通过面弓转移系统用于在传统牙合架上安装模型，另一组使用SAM牙合架在牙合平面指示器平台（OPI）上安装模型。之后，对模型安装的准确性进行分析。头颅侧位片中牙合平面与FHP形成的角度应等于牙合平面与牙合架上半部分之间的角度。
测量数据记录在Microsoft Excell（®）中，并使用单向方差分析进行计算。从统计学角度来看，结果未显示各项测量之间存在显著差异。
OPI和面弓呈现出相似的结果，但需要更多研究来验证其相对于OPI中上颌斜度的准确性，或开发能够解决每种技术缺点的新技术。
