Objective To compare the effects of resin aesthetic restoration and crown reattachment restoration for patients with traumatic injuries to young permanent teeth and its inffuence on aesthetics and satisfaction. Methods A total of 80 patients with traumatic injuries to young permanent teeth (80 affected teeth) admitted to Chaoshan Hospital, the First Afffliated Hospital of Jinan University from January 2023 to August 2025 were selected, and they were divided into the control group and the observation group by the random number table method, with 40 patients (40 affected teeth) in each group. The control group received resin aesthetic restoration, and the observation group received crown reattachment restoration. The restoration success rate, clinical efffcacy, aesthetics, satisfaction and complication rate were compared between the two groups. Results The restoration success rate of the observation group (95.00%) was higher than that of the control group (80.00%) (P<0.05). The excellent and good rates of marginal adaptation, tooth morphology recovery and masticatory function score in the observation group were better than those in the control group (P<0.05). The scores of color matching and appearance coordination in the observation group were higher than those in the control group (P<0.05). The satisfaction of the observation group was 97.50%, which was higher than 82.50% of the control group (P<0.05). The incidence of complications in the observation group was lower than that in the control group (P<0.05). Conclusion Crown reattachment restoration has deffnite efffcacy in the treatment of traumatic injuries to young permanent teeth, with better postoperative aesthetics, higher patient satisfaction and lower risk of complications.
