Effects of fixed appliance orthodontic combined with implant denture repair in treatment of patients with dentition defects and malocclusion
Objective:To observe effects of fixed appliance orthodontic combined with implant denture repair in treatment of patients with dentition defects and malocclusion.Methods:A prospective study was conducted on 82 patients with dentition defects and malocclusion admitted to the hospital from June 2019 to June 2021.According to the coin tossing method,they were divided into observation group and control group,41 cases in each group.The control group was treated with implant denture repair,while the observation group was treated with fixed appliance orthodontic treatment on the basis of that of the control group.The excellent and good rate of treatment,the masticatory efficiency,the pink esthetic index(PES)score,the white aesthetic index(WES)score,and the incidence of complications were compared between the two groups.Results:The excellent and good rate of treatment in the observation group was 95.12%,which was significantly higher than 80.49%in the control group,and the difference was statistically significant(P<0.05).Three months after repair treatment,the masticatory efficiencies of the two groups were higher than those before the treatment,that of the observation group was higher than that of the control group,and the differences were statistically significant(P<0.05).Three months after repair treatment,the PES,WES scores of the observation group were higher than those of the control group,and the differences were statistically significant(P<0.05).Further,the incidence of complications in the observation group was 4.88%,which was significantly lower than 24.39%in the control group,the difference was statistically significant(P<0.05).Conclusions:Fixed appliance orthodontics combined with implant denture repair for the patients with dentition defects and malocclusion can improve the excellent and good rate of treatment,the masticatory efficiency,the PES and WES scores,and reduce the incidence of complications.Moreover,it is superior to single implant denture repair.
