The effects of orthodontic micro implants on the dental aesthetics,oral structure,and periodontal microenvironment in patients with Class Ⅱ malocclusion
Objective To analyze the impact of orthodontic micro implants on patients with Class Ⅱ malocclusion.Methods A total of 84 patients with Class Ⅱ malocclusion admitted to the Stomatology Department of Shangqiu Traditional Chinese Medicine Hospital from May 2022 to May 2023 were selected as the study subjects.They were divided into two groups according to different treatment methods,with 42 cases in each group.The control group received traditional orthodontic treatment,while the observation group received orthodontic mini implant treatment.Compare the clinical efficacy,tooth aesthetics,chewing function,oral structure,oral health status,periodontal microenvironment,and complications between two groups.Results The total effective rate of the observation group was 95.24％(40/42),higher than the control group's 80.95％(34/42),and the incidence of complications was 7.14％(3/42),lower than the control group's 23.81％(10/42);After treatment,the Red Aesthetics Index(PES)score was(7.96±1.12)points,bite force was(73.49±7.84)Ibs,and chewing efficiency was(57.89±4.63)％,which was higher than the control group's(6.01±0.89)points,(75.21±6.48)Ibs,and(53.32±4.15)％.The distance of molar displacement was(3.69±0.53)mm,which was lower than the control group's(6.31±1.28)mm.The difference in inclination angle of the central incisors was(25.71±3.02)°,and the difference in protrusion distance of the upper central incisors was(4.19±0.68)mm,which was higher than that of the control group.12.48±2.35 °,(2.41±0.35)mm,gingival index(GI)is(0.63±0.06),plaque index(PL)is(0.80±0.11),matrix metalloproteinase-2(MMP-2)is(2.28±0.36)μ G/g,matrix metalloproteinase-9(MMP-9)is(2.40±0.21)μ G/g,lower than the control group's(0.89±0.15)points,(1.21±0.18)points,and(3.67±0.53)points μ G/g,(3.76±0.29)μ G/g(P<0.05).Conclusion Orthodontic micro implants can restore periodontal structure,improve periodontal microenvironment,enhance tooth aesthetics,and facilitate the improvement of chewing function without serious complications.
