Application of invisible appliances without brackets in patients with periodontitis and malocclusion deformity
Objective To investigate the effect of invisible appliances without brackets on periodontal health in patients with periodontitis and malocclusion deformity.Methods A total of 100 patients with periodontitis and malocclusion deformity treated at Hospital of Stomatology,Air Force Military Medical University from January 2022 to January 2024 were selected for the randomized controlled trail.The patients were divided into a control group and an observation group by the random number table method,with 50 cases in each group.There were 28 males and 22 females in the control group;they were(32.15±3.94)years old;their disease course was(25.45±4.16)months.There were 30 males and 20 females in the observation group;they were(32.52±3.88)years old;their disease course was(25.62±4.08)months.The control group were treated with straight wire appliances,and the observation group with invisible appliances without brackets.The therapeutic effects,periodontal health indicators[probing depth(PD),clinical attachment level(CAL),plaque index(PLI),and sulcus bleeding index(SBI)],gingival crevicular fluid inflammatory factors[interleukin-1β(IL-1β),interleukin-6(IL-6),human matrix metalloproteinase 8(MMP-8),and tumor necrosis factor-α(TNF-α)],appearance and function satisfaction,and incidence rates of complications were compared between the two groups.t and x2 tests were applied.Results The total effective rate in the observation group was higher than that in the control group[96.00％(48/50)vs.80.00％(40/50)],with a statistical difference(x2=6.222;P=0.012).Before the treatment,there were no statistical differences in the PD,CAL,PLI,SBI,and levels of IL-1 β,IL-6,MMP-8,and TNF-αbetween the two groups(all P＞0.05).After the treatment,the PD,CAL,PLI,SBI,and levels of IL-1 β,IL-6,MMP-8,TNF-α in the observation group were lower than those in the control group[(2.28±0.26)mm vs.(2.60±0.32)mm,(3.72±0.45)mm vs.(4.38±0.62)mm,(2.38±0.44)vs.(2.84±0.50),(1.80±0.27)vs.(2.12±0.34),(10.62±2.06)ng/L vs.(17.15±3.84)ng/L,(5.75±1.42)ng/L vs.(8.45±2.14)ng/L,(2 008.62±50.12)ng/L vs.(2 416.71±56.15)ng/L,and(15.55±2.12)ng/L vs.(25.87±3.17)ng/L],with statistical differences(t=5.487,6.091,4.883,5.211,10.596,7.433,38.339,and 19.135;all P＜0.05).After the treatment,the aesthetic satisfaction of the observation group was higher than that of the control group[98.00％(49/50)vs.82.00％(41/50)],with a statistical difference(x2=7.111;P=0.008).The incidence rate of complications in the observation group was lower than that in the control group[2.00％(1/50)vs.16.00％(8/50)],with a statistical difference(x2=4.395;P=0.036).Conclusion Invisible appliances without brackets for patients with periodontitis and malocclusion deformity can improve the therapeutic effect and their periodontal health,control the inflammatory factors in gingival crevicular fluid after treatment,reduce the occurrence of complications,and obtain satisfactory appearance,so it is worth being generalized.
