Application of glass fiber post combined with porcelain crown in repairing large area defect of anterior teeth
Objective To analyze the application of glass fiber post combined with porcelain crown in the restoration of large area defect of anterior teeth.Methods A total of 120 patients with large anterior tooth defect in Traditional Chinese Medicine Hospital of Luohe from September 2020 to March 2023 were selected and divided into the combined group and the single group according to random number table method,with 60 cases in each group.The single group was repaired with metal post cobalt-chromium porcelain crown,and the combined group was repaired with glass fiber post combined with all-porcelain crown.The clinical efficacy,masticatory efficiency,periodontal status[gingival crevicular bleeding index(SBI),probing depth(PD),clinical attachment loss(CAL)],gingival crevicular fluid[alkaline phosphatase level(ALP),gingival crevicular fluid matrix metalloproteinase 2(MMP2),intercellular adhesion molecular 1(ICAM-1)]and complication rates were compared between the two groups.Results The total effective rate of combined group was 95.00％(57/60),which was higher than that of single group(81.67％,49/60,P＜0.05).After repair,the masticatory efficiency of combined group was higher than that of single group(P＜0.05).After repair,the levels of PD,SBI and CAL in combined group were lower than those in single group(P＜0.05).After repair,the levels of MMP2,ALP and ICAM-1 in combination group were lower than those in single group(P＜0.05).The complication rate of the combined group was 5.00％(3/60),which was lower than that of the single group(16.67％,10/60,P＜0.05).Conclusions The combination of glass fiber post and porcelain crown can improve the therapeutic effect,improve the masticatory efficiency,reduce the influence on periodontal tissue and gingival crevicular fluid,and reduce the incidence of complications,with good safety.
