GCF and GCF-AST expression in the zirconia ceramic restoration process evaluation

Objective To investigate dentition defects and tooth defects by zirconia all-ceramic restorations on periodontal tissue health.Methods The introduction of computer technology and clinical combination of aided design and production,and Ireland record zirconia ceramic restorations using a total of 60 teeth in 30 patients as research subjects,30 cases of a total of 60 teeth using a cobalt-chromium porcelain crown the prosthesis into the control group,clinical followup period of 12 months of follow-up analysis to evaluate the indicators of the neck,gingival crevicular fluid and aspartate aminotransferase indicators before and after the repair of the two groups of restorations.Results Found in the gingival crevicular fluid volume before and after the repair of the experimental group and aspartate aminotransferase in gingival crevicular fluid levels of data results showed no significant difference was statistically significant(P 0.05),while the control group before and after repair of gingival statistically significant differences in results found in the crevicular fluid volume and the level of alkaline phosphatase in gingival crevicular fluid(P 0.05).Conclusion Computer technology zirconia allceramic crowns with good stability and biocompatibility of no significant impact on periodontal health.
