Improvement of the mastication function of orthodontics combined with restoration in the treatment of deep overbite with severe lower anterior teeth attrition
PURPOSE:To observe the effect of orthodontics combined with restoration on masticatory function in deep overbite patients with severe lower anterior teeth attrition.METHODS:From January 2018 to January 2022,a total of 164 deep overbite patients with severe lower anterior teeth attrition were collected and divided into two groups according to different treatment plans:control group(72 patients,with restoration treatment)and experimental group(92 patients,with orthodontics combined with restoration treatment).The chewing efficiency of the two groups was evaluated,temporo-mandibular joint dysfunction index(DI),muscle palpation index(PI)and cranio-mandibular index(CMI)were calculated.The satisfaction with facial esthetic,the Chinese version of Oral Health Impact Scale-14(OHIP-14)and the repair satisfac-tion score were evaluated,the occurrence of adverse events between the two groups was compared.SPSS 23.0 software package was used for statistical analysis.RESULTS:After treatment,the chewing efficiency of the experimental group was significantly improved compared to the control group,while the DI,PI,and CMI were significantly reduced compared to the control group(P＜0.05).Compared with the control group,the satisfaction degree with facial esthetic and restoration in the experimental group was significantly higher,while the OHIP-14 score was significantly lower after treatment(P＜0.05).The incidence of adverse events in the experimental group was significantly decreased compared with the control group(6.52％vs 25.00％,P＜0.05).CONCLUSIONS:Combination of orthodontics and restoration treatment can enhance the effectiveness of restoration treatment for deep overbite with severe lower anterior teeth attrition,improve the mastica-tion function and temporomandibular joint balance,satisfaction and quality of life of patients,as well as reduce the risk of adverse events.
