| Objective:For the patients clinically diagnosed as malocclusion with periodontal disease,two different kinds of orthodontics,namely invisible orthodontics and fixed orthodontics,were used to treat them.The periodontal status and concentration of related inflammatory factors were compared between the two groups during treatment,and the influence of invisible orthodontics on malocclusion with periodontal disease was further evaluated.In order to provide guidance for malocclusion with periodontal disease deformity to choose more conducive to the health of periodontal soft and hard tissue orthodontics.Methods:A total of 64 patients with periodontal disease and malocclusion who met the inclusion criteria in the second orthodontic Department of Hefei Stomatological Hospital from September 2020 to February 2022 were collected and randomly divided into experimental group(invisible appliance treatment group)and control group(fixed appliance treatment group).After periodontal treatment,orthodontic treatment was performed in both groups.Ramfjord index teeth(16,21,24,36,41,44)were selected to record periodontal indexes,including gingival index(GI),gingival creval bleeding index(BI),plaque index(PLI),and periodontal probing depth(PD).That is,the location with the largest PD value in periodontal probing examination was used as the collection point of gingival crevicular fluid sample.The mean values of various periodontal indices of all patients at different stages of orthodontic treatment after periodontal treatment were recorded,that is,before treatment and at 1,3,6 and 9 months after treatment.Gingival crevicular fluid of patients at corresponding time periods was extracted and the concentrations of interleukin-1 β and tumor necrosis factor(TNF)-α in the fluid were measured.SPSS19.0 analysis software was used,counting data was expressed as percentage(%),and chi-square test was conducted.The measurement data were expressed as(x ± s)and T-test was used.The comparison of indicators at different time points between the two groups was performed by repeated measure analysis of variance.P < 0.05 was considered to be statistically significant.Results:1.After the treatment,the gingival index(GI)of the experimental group and the control group increased significantly at the 1st,3rd,6th and 9th month,but the gingival index(GI)of the experimental group was significantly lower than that of the control group,the difference was statistically significant(P < 0.05).2.After the treatment,the bleeding index(BI)of the experimental group and the control group increased significantly at the 1st,3rd,6th and 9th month,but the bleeding index(BI)of the experimental group was significantly lower than that of the control group,the difference was statistically significant(P < 0.05).3.After the treatment,the plaque index(PLI)of the experimental group and the control group increased significantly at the 1st,3rd,6th and 9th month,but the plaque index(PLI)of the experimental group was significantly lower than that of the control group,the difference was statistically significant(P < 0.05).4.After the treatment,the depth of periodontal probing(PD)in the experimental group and the control group increased significantly at the 1st,3rd,6th and 9th months,but the depth of periodontal probing(PD)in the experimental group was slightly lower than that in the control group,and the difference was not statistically significant(P > 0.05).5.After the treatment of the experimental group and the control group,the concentration level of tumor necrosis factor(TNF)-α was significantly increased at the 1st,3rd,6th and9 th months after treatment,but the concentration of the experimental group was significantly lower than that of the control group,the difference was statistically significant(P < 0.05).6.After the treatment of the experimental group and the control group,the concentration level of interleukin(IL)-1β was significantly increased at the 1st,3rd,6th and 9th months after treatment,but the concentration of the experimental group was significantly lower than that of the control group,the difference was statistically significant(P < 0.05).Conclusion:1.Due to the simple structure without brackets,the features of being put on by the patient to facilitate cleaning,the gentle and intermittent application of force and the control of force in the three-dimensional direction after tooth wrapping,the invisible orthodontic device can improve the occlusal alignment and better maintain the periodontal health of patients with periodontal disease and malocclusion.2.Patients with periodontal disease accompanied by malocclusion deformity have complex periodontal tissue status and poor treatment tolerance.In clinical treatment of such patients,it is necessary to design appropriate tooth movement plan and select appropriate orthodontics.3.When the fixed appliance is used to treat the patients with periodontal disease and malocclusion,the oral hygiene of the patients should be closely monitored and timely transferred to the periodontal department for treatment.During the treatment,the tooth should be moved slowly and over small distances with light force. |
