Abstract
Objective To observe the effect of zirconia all-porcelain crown on the prosthesis of maxillary anterior teeth and its effect on aesthetic index and dental Plaque index.Methods A total of 104 patients with maxillary anterior tooth defect were selected for hospital treatment and enrolled from January 2020 to January 2022.The patients were divided according to random number table method.52 patients were in the conventional repair group and given cobalt-chromium porcelain crown repair,and 52 patients were in the zirconia repair group and given zirconia all-porcelain crown repair.Gingival crevicular fluid(GCF)level was measured before and after repair 1 month,and Tumor necrosis factor-α in GCF was detected.TNF-α,Aspartate aminotransferase(AST)and Matrix metalloproteinase-8(MMP-8)levels were detected.One year after repair,the patients were evaluated for gingival condition,implant fixation,marginal suitability,implant appearance,secondary caries,and aesthetic index.The plaque index and gingival index of the patients were detected before and 1 year after repair,and Oral Health Impact Scale 14(HIP-14)was evaluated for the occurrence of adverse reactions in the two groups.Results After 1 month,the contents of GCF,TNF-α,AST and MMP-8 in zirconia repair group were significantly lower than those in conventional repair group(P＜0.05).The biting force of zirconia repair group was higher than that of conventional repair group(P<0.05).One year after restoration,the plaque index and gingival index of zirconia restoration group were lower than those of conventional restoration group(P＜0.05),and the gingival condition,shape and aesthetic index scores of zirconia restoration group were lower than those of conventional restoration group(P＜0.05).The scores of mental state,oral pain,independence and physical function in zirconia repair group were significantly lower than those in conventional repair group(P＜0.05).The incidence of black line,color change,gingivitis,food impaction and gingival irritation in zirconia repair group were lower than those in conventional repair group(P＜0.05).Conclusion In patients with maxillary anterior tooth defect,the full porcelain crown of zirconia can reduce the levels of inflammatory factors,GCF,AST and MMP-8,improve the chewing ability of teeth,reduce the plaque index,gingival index and aesthetic index,improve the dental repair effect and quality of life of patients,and reduce the incidence of adverse reactions.关键词
