Objective To explore the effect of oral digital technology in prosthodontics. Methods A total of 64 patients who underwent prosthodontics admitted to our hospital from December 2020 to December 2022 were selected as the research objects. They were divided into control group and experimental group by random number table method, with 32 patients in each group. The control group was given routine repair technology, and the experimental group was given oral digital technology. The repair effect and complication rate of the two groups were compared. Results The oral occlusal function, aesthetics, tissue health and adaptability of the experimental group were better than those of the control group, and the differences were statistically significant (P<0.05). The incidence of complications in the experimental group was lower than that in the control group, the difference was statistically significant (P<0.05). Conclusion The application of digital technology in prosthodontics can improve oral occlusal function, aesthetics, tissue health and adaptability, ensure the best effect and reduce the incidence of complications.
