The purpose of this study was to compare postintervention pain related to orthodontic treatment and orthognathic surgery. . One hundred patients who received only orthodontic treatment are the nonsurgical group. One hundred other patients were separated equally into the following four orthognathic surgical subgroups. The visual analog scale (VAS) score was used to measure postoperative pain. Patient- and operation-related factors were compared among the four surgical subgroups. The null hypothesis was that there was no difference between orthodontic treatment and orthognathic surgery in terms of posttreatment pain.
There were no significant differences between the nonsurgical and surgical groups for gender ( = 0.780) or age ( = 0.473). The VAS scores of the nonsurgical group (mean: 3.59) were significantly ( = 0.007) higher than those of the surgical group (mean: 3.06). The null hypothesis was rejected. Within the surgical subgroups, no significant differences were observed between the men and women for age, operation time, blood loss volume, or blood laboratory values.
The VAS scores of the orthodontic (nonsurgical) group were significantly higher than those of the surgical group. No significant differences in VAS scores were found between the four surgical subgroups.
本研究旨在比较正畸治疗和正颌手术的干预后疼痛。选择仅接受正畸治疗的 100 例患者为非手术组，另外 100 例患者平均分为以下四个正颌手术亚组。采用视觉模拟评分法（VAS）测量术后疼痛。比较四个手术亚组中患者和手术相关因素。零假设是正畸治疗和正颌手术在治疗后疼痛方面没有差异。
非手术组和手术组在性别（ = 0.780）或年龄（ = 0.473）方面无显著差异。非手术组的 VAS 评分（均值：3.59）明显高于手术组（均值：3.06）（ = 0.007）。零假设被拒绝。在手术亚组中，男性和女性在年龄、手术时间、失血量或血液实验室值方面无显著差异。
正畸（非手术）组的 VAS 评分明显高于手术组。四个手术亚组的 VAS 评分无显著差异。
