Objective To explore the effect of different fixation methods on dental health in patients with traumatic complete dislocation of permanent anterior teeth. Methods A total of 60 patients with traumatic complete dislocation of permanent anterior teeth admitted to the Department of Stomatology, Qidong Hospital of Traditional Chinese Medicine from January 2021 to January 2023 were selected as the research subjects. According to different fixation methods, they were divided into the control group and the observation group, with 30 patients in each group. The control group was treated with metal wire-resin splint, and the observation group was treated with full dentition occlusal splint fixation. The clinical efficacy, dental health, aesthetic effect, satisfaction and masticatory function were compared between the two groups. Results The total effective rate of the observation group (100.00%) was higher than that of the control group (80.00%) (P <0.05). The scores of GI and PLI in the observation group after treatment were lower than those in the control group, and the score of OHIP-14 was higher than that in the control group (P <0.05). The scores of PES and VAS in the observation group after treatment were higher than those in the control group (P <0.05). The score of CFQ in the observation group after treatment was lower than that in the control group (P <0.05). Conclusion Full dentition occlusal splint fixation is an efficient method for the treatment of complete dislocation of permanent anterior teeth. This technology can not only improve dental health and masticatory function, but also restore facial aesthetics, with high patient satisfaction.
