Aesthetic Effect of Bracketless Invisible Appliance on Patients with Periodontitis-induced Anterior Tooth Sector Displacement and the Effect on Inflammatory Factors
Aesthetic Effect of Bracketless Invisible Appliance on Patients with Periodontitis-induced Anterior Tooth Sector Displacement and the Effect on Inflammatory Factors
Objective To investigate the effect of non bracket invisible appliance on the aesthetic effect and the level of inflammatory factors in patients with fan-shaped displacement of anterior teeth caused by periodontitis.Methods 118 patients with fan-shaped displacement of anterior teeth caused by periodontitis admitted to author's hospital from March 2019 to March 2020 were divided into group A(53 patients with self-locking bracket appliance)and group B(65 patients with non bracket invisible appliance)according to different correction methods.The periodontal indexes,inflammatory factor levels,aesthetic effect scores and clinical efficacy were compared between the two groups.Results After 6 months of treatment,attachment loss(AL)sulcular bleeding index(SBI)plaque index(PLI)probing depth(PD)gingivalindex(GI)and interleukin 4(IL-4),interleukin 6(IL-6),tumor necrosis factor alpha(TNF-α)levels of the two groups were decreased,and the PLI,GI,SBI,PD,AL,IL-4,IL-6 and TNF-α levels of group B were lower than those of group A(P<0.05).After treatment,the scores of aesthetics,convenience,language function,and chewing function in group B were higher than those in group A(P<0.05).The total clinical effective rate of group B was higher than that of group A(P<0.05).Conclusion The bracket-free invisible appliance for the treatment of periodontitis-induced fan-shaped displacement of the anterior teeth can improve the oral microenvironment and reduce inflammatory reaction in the treatment of fan-shaped displacement of anterior teeth caused by periodontitis,with ideal aesthetic effect and high clinical efficiency.
