This study measured the amount of positional change in the terminal transverse horizontal axis of the mandible that results from altering undesirable neuromuscular influence. Centric relation records were made on 19 healthy subjects before and after deprogramming. The axis was located with a computerized axiograph, and the centric relation records were compared in vivo at the axis location. The positional change of the axis was quantified in three dimensions at an accuracy of +/- 0.05 mm. The net amount of positional change was compared to scores from the temporomandibular joint scale to test for correlation with the potential for developing a temporomandibular disorder. The findings showed that the amount of positional change in the terminal transverse horizontal axis in 18 of 19 healthy patients after 12 hours of deprogramming was less than 0.5 mm and did not correlate with scores from the TMJ Scale.
本研究测量了因改变不良神经肌肉影响而导致的下颌骨终末横向水平轴位置变化量。在19名健康受试者进行去程序化治疗前后记录正中关系。使用计算机轴描仪确定轴的位置，并在轴位置对正中关系记录进行体内比较。轴的位置变化在三个维度上进行量化，精度为±0.05毫米。将位置变化的净量与颞下颌关节量表的得分进行比较，以测试与发生颞下颌关节紊乱可能性的相关性。研究结果表明，19名健康患者中有18名在去程序化治疗12小时后，终末横向水平轴的位置变化量小于0.5毫米，且与颞下颌关节量表的得分无关。
