Clinical Application of Digital Indirect Bonding Technique in the Correction Treatment of Permanent Teeth Malocclusion
Objective To explore the clinical effect of digital indirect bonding technique in the correction treatment of permanent teeth malocclusion.Methods 184 patients with permanent teeth malocclusion who were treated in the hospital from June 2019 to June 2021 were selected as the observation subjects,and they were divided into observation group and control group by the block randomization method,with 92 cases in each group.The control group was treated with traditional correction method,and the observation group was given digital indirect bonding technique for correction treatment.The correction effect and aesthetic effect after 12 months of treatment and changes in masticatory function(occlusal force,masticatory efficiency)and periodontal health[debris index(DI),calculus index(CI),plaque index(PLI)]before treatment and after 12 months of treatment were compared between the two groups.Results After 12 months of treatment,the scores of tooth alignment,marginal ridge height,occlusal relationship,adjacent relationship and abnormal degree of root parallelism in observation group were significantly lower than those in control group,while the orderly teeth,occlusal force of posterior teeth and anterior overjet rate were significantly higher than those in control group(all P＜0.05).The occlusal force and masticatory efficiency in the two groups were significantly improved after 12 months of treatment,and the two indicators in observation group were significantly higher than those in control group(P＜0.05).The DI,CI and PLI were significantly decreased,and the three indicators in observation group were significantly lower compared with those in control group(P＜0.05).Conclusion For patients with permanent teeth malocclusion,digital indirect bonding technique can achieve both oral function and aesthetic effect,thus it is worthy of clinical promotion.
