Observation on the Aesthetic Effect of Orthodontic Fixed Traction Root Fracture Combined with Repair in the Treatment of Anterior Subgingival Crown Fold
Objective To study the application effect of orthodontic fixed traction combined with root fracture repair treatment in aesthetic restoration of anterior teeth.Methods 76 patients with anterior subgingival crown fold in front teeth admitted to the author's hospital from May 2020 to May 2023 were randomly divided into a control group(n=38)and an observation group(n=38).Both groups of patients were treated with extirpation of pulp and root canal therapy.After one month of root canal therapy,the control group underwent gingival resection and porcelain restoration,while the observation group received orthodontic fixed traction combined with porcelain restoration treatment.Follow up for 1 year,the excellent and good treatment rates,anterior occlusal function,periodontal health,aesthetic effects,total treatment duration,treatment cost,satisfaction,and incidence of complications of two groups of patients were compared.Results The excellent and good treatment rate in observation group was significantly higher than the control group(97.37% vs.84.21%,P＜0.05).The restoration of anterior teeth occlusion function in observation group was higher than the control group,and the IPC-HB and IPC-MC electromyographic values were significantly higher(P＜0.05).The periodontal health status of the observation group was better than the control group,with higher PES and WES indexes(P＜0.05).The total treatment duration and treatment cost of the observation group were significantly higher than those of the control group(P＜0.05).The satisfaction rate of patients in the observation group was higher than the control group(97.37% vs.73.68% ),and the incidence of various complications was significantly lower(P＜0.05).Conclusion The orthodontic fixed traction combined with root fracture repair treatment of aesthetic defects in front teeth had a positive effect,can help to restore the occlusal function of the anterior teeth,maintain periodontal health and aesthetic effects,reduce the incidence of complications,and improve patient satisfaction.
