Based on the level of inflammatory factors in gingival crevicular fluid and the occlusal function of teeth,the effect of invisible and fixed correction without brackets on the patients with malocclusion deformity
Objective:To compare the therapeutic effects of invisible correction without brackets and fixed correction on the levels of inflammatory factors in gingival crevicular fluid and the occlusal function of teeth in patients with malocclusion deformity.Methods:Retrospectively collected the case data of 92 patients with malocclusion who were admitted to our hospital from May 2021 to May 2023.The patients were divided into two groups according to the different surgical plans(n=46).The observation group received invisible orthodontics without brackets,while the control group received fixed orthodontics.The treatment effects of the two groups were compared after six months of treatment.Before treatment,after three months,and after six months of treatment,the periodontal health indicators including gingival index(GI),sulcus bleeding index(SBI),plaque index(PLI),periodontal depth(PD),and complication rate were measured.The Tee Tester bite force detector was used to measure the teeth'bite function,such as the total value of occlusal force,maxim assume displacement of occlusal force center point,and asymmetric index of occlusal force.The enzyme-linked immunosorbent assay was used to detect the inflammatory factors levels in the gingival crevicular fluid,such as interleukin-6(IL-6),soluble intercellular adhesion molecule-1(sICAM-1),and interleukin-1β(IL-1β).Results:The total effective rate of the observation group was 97.83%(45/46),which was higher than the 78.26%(36/46)in the control group(P<0.05).Compared with before orthodontic treatment,the GI,SBI,PLI,and PD in each treatment group were significantly decreased(P<0.05),and the observation group was more significant(P<0.05).Compared with before orthodontic treatment,the total value of the occlusal force in each treatment group was significantly increased,the maximum displacement of the occlusal force center point and the asymmetry index of the occlusal force was significantly decreased,and the observation group was more significantly(P<0.05).Compared with before orthodontic treatment,the levels of IL-6,sICAM-1,and IL-1β in gingival crevicular fluid in each treatment group were significantly increased,and the control group was more significant(P<0.05).The incidence of complications in the observation group was 4.35%(2/46),which was lower than the 21.74%(10/46)in the control group(P<0.05).Conclusion:The overall correction effect of patients with malocclusion who undergo invisible braces is better than that of fixed braces.
