Effect of Different Repair Materials on the Success Rate of Repair and Periodontal Tissue
Objective To analyze the effects of zirconia and cobalt-chromium alloy repair materials on the success rate of repair and the level of inflammatory factors in gingival crevicular fluid(GCF)in patients with oral repair.Methods A total of 86 patients who received oral prosthesis from September 2019 to September 2022 in Luoyang Third People's Hospital were divided into group A(received zirconia prosthesis treatment)and group B(received cobalt-chromium alloy prosthesis treatment)according to prosthetic schemes,with 43 cases in each group.The success rate of restoration,periodontal indicators[gingival bleeding index(BI),periodontal probing depth(PD),plaque index(PLI),GCF volume],GCF inflammatory factors[interleukin-8(IL-8),interleukin-6(IL-6),matrix metalloproteinase-2(MMP-2)],bone change-related factors[tumor necrosis factor-related weak apoptosis-inducing factor(TWEAK),receptor activator of nuclear factor-κB ligand(RANKL),RANKL/osteoprotegerin(OPG)],and dental function were compared between the two groups.Results The success rate of repair in group A was higher than that in group B(P<0.05).After 6 months of treatment,BI and PD increased in group B(P<0.05),while BI and PD were lower in group A than in group B(P<0.05).After treatment,the levels of IL-8,IL-6,and MMP-2 in both groups increased,and the level in group B was higher than that in group A(P<0.05).After treatment,TWEAK,RANKL,and RANKL/OPG levels increased in both groups,and group B was higher than group A(P<0.05).Compared with group B,the scores of masticatory function,comfort,dental aesthetics,and language function in group A increased significantly after treatment(P<0.05).Conclusion Compared with cobalt-chromium alloy prosthesis,zirconia prosthesis has less stimulation on periodontal tissue of patients with oral prosthesis,and the level of inflammatory factors in GCF is lower,which has less influence on the degree of alveolar bone absorption,stronger tooth function and higher success rate of prosthesis.
