Application of Zirconia All Ceramic Crown in Maxillary Anterior Teeth Restoration and its Impact on Periodontal Tissue and Oral Environment
Objective:To investigate the application of zirconia(Zro2)all ceramic crowns in the restoration of maxillary anterior teeth and its impact on periodontal tissue health and oral environment.Methods:84 patients who were admitted to the hospital for maxillary anterior tooth restoration from May 2021 to January 2023 were selected as the study subjects.They were decided into the control group(42 cases,with nickel chromium alloy porcelain crown restoration)and the observation group(42 cases,with Zro2 all ceramic crown restoration)according to the random number table method.The restoration effect,periodontal tissue health status before and after restoration[Plaque Index(PLI),Gingival Index(GI),Bleeding Index(BI)],chewing function,and subgingival plaque detection were compared between the two groups.Results:The observation group showed higher levels of edge fit,estoration color,and secondary caries issues after repair compared to the control group(χ2=6.930,6.473,6.486;P＜0.05).After repair,the GI value,BI value,and PLI value of the observation group were lower than those of the control group(t=3.335,2.954,2.792;P＜0.05).After repair,chewing function indicators(bite force and chewing efficiency)in the observation group were higher than those in the control group(t=10.445,3.981;P＜0.05).The detection rates of Porphyromonas gingivalis,Fusobacterium nucleatum,Fusetan and Actinobacillus actinomycetes in the subgingival plaque in the observation group were lower than those in the control group after repair(χ2=5.973,6.222,4.086,4.480;P＜0.05).Conclusion:Zro2 all ceramic crowns had significant effect on patients with maxillary anterior tooth defects,and could significantly improve their chewing function and oral environment,maintaining periodontal tissue health.
