Objective To analyze the effect of ffxed orthodontic technology in the treatment of adults with impacted maxillary anterior teeth. Methods A total of 100 adult patients with impacted maxillary anterior teeth who were treated in the Department of Stomatology of our hospital from March 2019 to March 2024 were selected, and they were treated with fixed orthodontic technology. According to the position of impacted teeth and eruption potential, they were divided into the high-position group (n=32), middle-position group (n=45) and low-position group (n=23). After 12 months of follow-up, the treatment effect, treatment time, occlusal function indexes and aesthetic satisfaction were compared among the three groups. Results The total effective rate of the middle-position group (93.33%) was higher than that of the high-position group (71.88%) and low-position group (86.96%) (P<0.05). The treatment time of the middle-position group was shorter than that of the high-position group and low-position group (P<0.05). The occlusal function indexes of the middle-position group after treatment were better than those of the high-position group and low-position group (P<0.05). The aesthetic satisfaction score of the middle-position group after treatment was higher than that of the high-position group and low-position group (P<0.05). Conclusion Fixed orthodontic technology has a deffnite effect in the treatment of impacted maxillary anterior teeth in adults, which can restore the normal dental alignment, occlusal function and aesthetics. Among them, the middle-position impacted teeth have better treatment effect and shorter treatment time, while the high-position impacted teeth have higher treatment difffculty. Individualized treatment plans should be formulated according to the actual situation.
