Purpose. The purpose of this study was to compare postintervention pain related to orthodontic treatment and orthognathic surgery. Material and Methods. 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. Results. There were no significant differences between the nonsurgical and surgical groups for gender (P=0.780) or age (P=0.473). The VAS scores of the nonsurgical group (mean: 3.59) were significantly (P=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. Conclusions. 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.
