Abstract Objective: To investigate the effect of zirconia post plus zirconia crown and fiber post plus zirconia crown in repairing large area tooth defects. Methods: Totally 117 patients who received large-area tooth defect restoration in the hospital from April 2020 to April 2024 were included. With the random number table method, the patients were divided into the zirconia post group (n=61) and the fiber post group (n=56). The zirconia post group received zirconia post plus zirconia crown restoration, and the fiber post group underwent fiber post plus zirconia crown restoration. The patients were followed up for 6 months. The masticatory function (occlusal force, masticatory efficiency), restoration stability (PTV value), restoration time efficiency, gingival health [gingival bleeding index (BI), periodontal pocket depth (PD), gingival index (GI)], gingival crevicular fluid inflammatory factors [interleukin-1β (IL-1β), tumor necrosis factor α (TNF-α), prostaglandinE₂ (PGE₂)], restoration shedding status, edge tightness and aesthetic effect [pink esthetic score (PES), white esthetic score (WES)] were compared between groups before restoration and at 6 months after restoration. Results: After 6 months of restoration, the masticatory function in the two groups was significantly improved, and the differences of occlusal force and masticatory efficiency before and after restoration in the zirconia post group were higher than those in the fiber post group (P<0.05). The total restoration time was (12.00±3.50) days in the fiber post group and (27.00±7.50) days in the zirconia post group, and the time efficiency in the fiber post group was better than that in the zirconia post group (t=13.660, P<0.001). The stability of restorations in both groups was increased, and the difference of PTV value before and after restoration was higher in the zirconia post group than that in the fiber post group (P<0.05). The periodontal health status was improved in both groups at 6 months after restoration, and the differences of BI, PD and GI before and after restoration were greater in the fiber post group compared to the zirconia post group (P<0.05). The differences of IL-1β, TNF-α and PGE₂ before and after restoration in the fiber post group were greater compared with those in the zirconia post group (P<0.05). After 6 months of restoration, there were no statistical differences in the restoration shedding status and edge tightness between both groups (P>0.05). The differences of PES score and WES score before and after restoration in the fiber post group after 6 months of restoration were higher compared to the zirconia post group (P<0.05). Conclusion: Fiber post restoration has better performance in terms of time efficiency, aesthetic effect and periodontal health improvement, and zirconia post restoration has more advantages in masticatory efficiency and stability.
