The authors studied the lateral positional desviations of the mandible, in relation to the facial median line in 30 (thirty) full edentulous patients, with the purpose to verify the influence of the unstrained guided (chinpoint guidance) and deglutition methods for the determination of centric relation. According the results obtained they conclude that the unstrained guided method produced a mandibular lateral desviation with a mean value of the 0.752 mm and in the deglutition method the mean value observed was 1.109 mm. The statistical analysis of the results revealed for the unstrained guided method a proportion of the "points" to the right and left of the median line not statistically significant, while for the deglutition method the difference was statistically significant at a level of 5%.
作者研究了30名全口无牙患者下颌骨相对于面部中线的侧向位置偏差，目的是验证无约束引导（颏点引导）和吞咽方法对确定正中关系的影响。根据所得结果，他们得出结论，无约束引导法产生的下颌侧向偏差平均值为0.752毫米，吞咽法观察到的平均值为1.109毫米。结果的统计分析显示，无约束引导法在中线左右两侧的“点”的比例无统计学意义，而吞咽法在5%的水平上差异具有统计学意义。
