Abstract Objective To explore the effect of glass fiber post combined with all-ceramic crowns in repairing large-area defects of anterior teeth and its influence on chewing ability. Methods A total of 82 (112 teeth) with large anterior teeth defects admitted to the 904th Hospital, Joint Logistic Support Force of the Chinese People’s Liberation Army from August 2018 to August 2020 were selected, they were divided into control group (41 cases, 54 teeth) and study group (41 cases, 58 teeth) according to the random number table method. The control group was repaired metal post cobalt-chromium porcelain crowns, while the study group was repaired glass fiber post combined with all-ceramic crowns. Patients in both groups were followed up for six months, the repair effect, repair success rate, chewing efficiency, and gingival crevicular fluid metalloproteinase 2 (MMP2), intercellular adhesion molecule 1 (ICAM1), alkaline phosphatase (ALP) levels were compared, the incidence of complications during follow-up was recorded. Results The repair integrity, color matching, and edge fitness of study group were better than those of control group, and the differences were statistically significant (P < 0.05). The repair success rate of study group was higher than that of control group, and the difference was statistically significant (P < 0.05). Six months after restoration, the chewing efficiency of two groups were higher than that before restoration, and study group was higher than control group, and the differences were statistically significant (P < 0.05). Six months after restoration, the levels of gingival crevicular fluid MMP2, ICAM1, and ALP were higher than those before restoration, and study group was lower than control group, and the differences were statistically significant (P < 0.05). There was no significant difference in the incidence of complications between two groups (P > 0.05). Conclusion The glass fiber post combined with all-ceramic crown has a good effect in repairing large-area defects of anterior teeth, and high success rate, at the same time, the periodontal tissue stimulation is less, so it is a safe and reliable repair method.
