By applying the theoretical equation concerning the direction of tooth guidance to three subjects, which was statistically based on the direction of balancing condylar path, their stomatognathic functions were discussed. The stomatognathic functions were evaluated by clinical symptoms, madibular movements and muscle activities as parameters.Following conclusions were obtained :1. Depending on the direction of tooth guidance calculated from the theoretical equation, that of subjects should be gentler or steeper.2. In reconstructing the direction of tooth guidance :(I) some could be removed clinical symptoms.(2) mandible was smoothly moved, not even effecting on the condylar path.(3) left and right masseter muscles, anterior temporal muscles, posterior temporal muscles nearly showed ordinary activities.3. It became obvious in the stomatognathic function what theoretical equation means.

应用以髁突平衡轨迹方向为基础的牙齿导向方向理论方程，对3名受试者的口颌功能进行了分析。以临床症状、下颌运动和肌肉活动度为指标评价口颌功能。根据理论公式计算出的牙导方向，受试者的牙导方向应是平缓的还是陡峭的.在重建方向上牙导：（1）部分可去除临床症状。(2)下颌运动平稳，不影响髁突路径。(3)左右咬肌、颞前肌、颞后肌活动基本正常.在口颌功能中，理论方程的含义变得显而易见。
