目的：目的：探讨义齿修复对全口义齿患者咀嚼运动的影响。方法：对48例需更换全口义齿的患者和20例对原全口义齿满意的患者（对照组：C组）进行研究。受试者被要求在他们习惯咀嚼的一侧咀嚼软糖。下颌运动记录仪记录下颌切点的运动。首先，显示第5周期和第14周期之间的10个周期的平均路径和移动路径的重叠。将运动路径分为7种模式，计算每种模式出现的频率，并探讨治疗与咀嚼路径模式的关系。接下来，开口距离和咀嚼宽度（空间参数）和循环时间比较治疗前组与治疗后组的时间参数（BT组）和治疗后组AT组与C组比较，差异有统计学意义（P < 0. 05）。BT组的咀嚼路径呈多样性，而AT组和C组中的大多数受试者显示出代表健康齿状受试者的路径模式。结论：AT组与C组相比，戴用新义齿后咀嚼运动明显改善，咀嚼宽度增加，咀嚼运动周期缩短，但差异无统计学意义。(C)2018日本口腔修复学会。由爱思唯尔有限公司出版。保留所有权利。
Purpose: To clarify the effect of denture treatment on masticatory movement in patients with complete dentures.Methods: Forty eight patients who required new complete dentures and 20 patients who were satisfied with their original complete dentures (control: C group) participated in this study. Subjects were asked to chew a gummy jelly on their habitual chewing side. The movement of mandibular incisal point was recorded using a mandibular kinesiograph. First, average path and overlap of the movement path were displayed for the ten cycles between the fifth cycle and the fourteenth cycle. The movement path was classified into one of seven patterns and the frequency of each pattern was calculated and investigated the relationship between treatment and masticatory path pattern. Next, opening distance and masticatory width (spatial parameter) and cycle time (temporal parameter) were calculated and compared between the before treatment group (BT group) and after treatment group (AT group), and between the AT and C groups.Results: The BT group showed various patterns of masticatory path, whereas the majority of subjects in the AT and C groups showed path patterns that were representative of healthy dentate subjects. The opening distance and masticatory width increased, and the cycle time was shortened after wearing new complete denture, and there were no statistically significant differences between AT group and C group.Conclusions: From these results it was suggested that the masticatory movement of patients with complete dentures improved greatly after wearing new denture.
