Abstract Objective: To observe the effect of zirconia on the mastication ability and the restorative effect. Methods: 96 patients were randomly divided into observation group and control group, 48 patients in each group. Patients in the control group were treated with ni-cr alloy prosthesis and patients in the observation group were treated with zirconia prosthesis. The repair effect of the two groups was observed, as well as the changes of chewing ability, gingival index, IL-6 and IL-8 in gingival crevicular fluid before and after repair, and the repair quality. Results: After treatment, the bite force and chewing ability of the two groups were improved, and the improvement effect of the observation group was better, and the difference between the groups was statistically significant (P<0.05).The high quality rate of treatment in the observation group was better than that in the control group, and the difference between the groups was statistically significant (P<0.05).After treatment, gingival index, bleeding index and plaque index were improved in both groups, and the improvement effect was better in the observation group, with statistically significant difference between groups (P<0.05).The levels of IL-6 and IL-8 in gingival crevicular fluid in the observation group after repair were lower than those in the control group, and the difference between groups was statistically significant (P<0.05). In the observation group, the rate of edge tightness was higher than that of the control group, and the fracture rate of the restoration body and porcelain breakage rate of the restoration body were lower than that of the control group, with statistically significant difference (P<0.05). Conclusion: the application of zirconia prosthesis in the treatment of patients with oral prosthesis has a good effect, which can significantly improve the chewing ability of patients and improve the gingival function.
