With the experimental design of this study the following conclusions were reached. 1. Biting force during maximum clenching was the greatest when the occlusal plane was made parallel to the ala-tragus line. It decreased when the occlusal plane was inclined about 5 degrees anteriorly or about 5 degrees posteriorly. 2. The efficiency of biting force exertion during maximum clenching showed the best value when the occlusal plane was made parallel to the ala-tragus line. 3. Muscle activity during clenching at various given forces was least when the occlusal plane was made parallel to the ala-tragus line. The anteroposterior inclination of the occlusal plane tends to affect the biting force, and the method with the ala-tragus line seems to be the most reasonable for occlusal plane orientation.
基于本研究的实验设计，得出了以下结论。1. 当咬合平面与鼻翼 - 耳屏线平行时，最大紧咬时的咬合力最大。当咬合平面分别向前倾斜约5度或向后倾斜约5度时，咬合力会降低。2. 当咬合平面与鼻翼 - 耳屏线平行时，最大紧咬时咬力施加的效率显示出最佳值。3. 当咬合平面与鼻翼 - 耳屏线平行时，在各种给定力下紧咬时的肌肉活动最少。咬合平面的前后倾斜倾向于影响咬合力，并且使用鼻翼 - 耳屏线的方法似乎是咬合平面定位最合理的方法。
