| Objective: In this experiment, the Computerized Occlusal Analysis System wereused to analyze the occlusion of periodontitis with occlusal trauma patients andperiodontally healthy subjects. Compared with the Occlusion Time,provide a referenceindex for the diagnosis of occlusal trauma;Through the detection of premature contactsand occlusal interference point to occlusal trauma, and provide a new auxiliaryexamination method of occlusal adjustment in occlusal trauma,which can make makeocclusal adjustment more accurate and effective.Methods: To select42cases of patients with moderately severe periodontitis withocclusal trauma, male21, female21, which were randomly divided into groupA, andgroup B,and each group of21people, aged35to74years old, while collecting20periodontally healthy volunteers served as group C (control group), male10and female10,aged35to74years old.Compared periodontitis with occlusal trauma groups and the control group in theOT, and then gave the periodontitis with occlusal trauma groups periodontal therapy(including supragingival scaling and subgingival scaling), after6weeks, OT, functionalmobility (FM) and periodontal clinical index were compared,to see the improve ofocclusal trauma and inflammation;later on，gave the periodontitis with occlusal traumagroups occlusal therapy,later on periodontitis with occlusal trauma group of occlusaltherapy, group A on the basis of using traditional methods with the ComputerizedOcclusal Analysis System, group B only using the methods without Computerized Occlusal System. To compare therapeutic effect,one month after treatment, comparedtwo groups of OT,FM and clinical periodontal examination index again.The experimental groups were in accordance with the "periodontology" FourthEdition periodontal examination and grading standards, a detailed record of eachselected patients with full mouth teeth, and shoot panoramic X-ray panoramicradiographs, check and record the following periodontal examination index of fulldentition: bleeding index (BI),probing depth (PD), attachment loss (AL), functionalmobility (FM); and use the Occlusal Analysis System recording occlusion time (OT).SPSS13.0software package was used for statistical analysis of data, measurementdata were expressed as x±s, compared with the measurement data were analyzed bypaired t test or variance.Results: No difference in A, B, C groups of gender, age (P>0.05); there was nodifference in group A and group B of AL, PD, BI (P>0.05); there was no significantdifference in group A and group B of OT, FM (P>0.05), but were higher than those ofOT in group C, the difference was statistically significant (P<0.05).A month after periodontal treatment, groups A and B of OT compared with beforetreatment were decreased, The difference was statistically significant (P<0.05),but stillhigher than the control group, the difference was statistically significant (P<0.05);compared with before treatment, groups A and B of AL, PD, BI, FM were decreased,the difference was statistically significant (P<0.05)A month after occlusal adjustment, groups A and B of AL, PD, BI have decreasedcompared with before treatment (P<0.05), and group A was than those in group B, thedifference was statisticallysignificant (P<0.05); after treatment,both group A and groupB of OT decreased (P<0.05), the group A was higher than C, But the difference was notstatistically significant (P>0.05); group B was higher than group C, the difference wasstatisticallysignificant (P<0.05); groupA and group B of FM decreased after treatment,And the groupA was lower than that of group B, The difference wasstatisticallysignificant (P<0.05).Conclusion: Occlusion time quantitative analysis has significance in clinical diagnosis of moderate to severe periodontitis with occlusal traumaClinical application of Computerized Occlusal Analysis System examination canmoderate to severe periodontitis with occlusal trauma patients to provide quantitativereference index,and which can improve the effect of occlusal adjustment. |
