目的：本研究的目的是确定接受牙科治疗时身体和头部位置的变化如何影响下颌位置，并制定一套患者姿势标准。方法：对 8 名正常咬合且未患有任何口颌功能障碍的受试者进行下颌位置调查。这是通过使用 Gnathohexagraph（一种具有 6 个自由度的 3 维下颌运动测量装置）测量切点上的敲击点位置来完成的，受试者坐着时头部处于 4 个不同位置，仰卧时身体和头部处于 16 个不同位置，然后比较每个位置与参考位置的偏差。首先使用单向方差分析 (α=.05) 的重复测量进行数据统计分析，第二个 Bonferroni 多重比较测试在坐姿下进行。仰卧位重复测量2-way ANOVA，然后进行Bonferroni多重比较检验。结果：由于头部和身体位置的变化，切点在前后方向上存在明显偏差。当受试者坐着时，当受试者被要求从参考位置向后倾斜时，切点倾向于向后移动。当受试者被要求向前倾斜时，切点倾向于向前移动。当受试者处于仰卧位时，切点向后倾斜。无论身体后倾程度如何，随着头部位置从向后10度到向前20度变化，切点后倾程度趋于下降。结论：牙科治疗时身体和头部姿势的变化会影响切点偏差。
Purpose: The objectives of this study were to determine how changes in body and head position undergoing dental treatment affect mandibular position, and to develop a set of standards for patient posture.Methods: Mandibular position was investigated in 8 subjects with normal occlusion and not suffering any stomatognathic dysfunction. This was done by measuring the location of the tapping point on the incisal point using a Gnathohexagraph (a 3-dimensional jaw movement measurement device with 6 degrees of freedom), with the subject’s head in 4 different positions while sitting, and the body and head in 16 different positions with the subject supine, and then comparing deviation from the reference position in each of these positions. Statistical analysis of data was performed using first, repeated measures of 1-way ANOVA (α=.05), second Bonferroni’s multiple comparison test was undertaken in seated positions. In supine positions, repeated measures of 2-way ANOVA was performed, and followed by Bonferroni’s multiple comparison test was performed.Results: The incisal point deviated significantly in the anteroposterior direction due to changes in head and body position. With the subjects seated, the incisal point tended to move backwards when the subjects were asked to lean backwards from the reference position. The incisal point tended to move forward when the subjects were asked to lean forward. With the subjects in a supine position, the incisal point was inclined backwards. The degree of backwards inclination of the incisal point tended to decline as the head position was varied from 10 degrees backwards to 20 degrees forward, regardless of the degree of backwards inclination of the body.Conclusion: Changes in body and head posture undergoing dental treatment affect incisal point deviation.
