Objective To explore the effect of digital impression technology on aesthetic effect in patients undergoing anterior all-ceramic crown restoration. Methods A total of 62 patients undergoing anterior all-ceramic crown restoration in the Outpatient Department of Wuxi Huishan District People's Hospital from June 2023 to December 2024 were selected. According to the random number table method, they were divided into the control group and the experimental group, with 31 patients in each group. The control group received traditional silicone rubber impression technology, and the experimental group received digital impression technology. The aesthetic effect, periodontal health indexes and efffciency indexes were compared between the two groups. Results At 3 months after treatment, the scores of PES and WES in the two groups were higher than those before treatment, and those in the experimental group were higher than those in the control group (P<0.05). There were no statistically signiffcant differences in GI and PLI between the two groups (P>0.05). The clinical impression operation time and crown adjustment time in the experimental group were shorter than those in the control group (P<0.05). Conclusion Digital impression technology can effectively improve the aesthetic effect of anterior all-ceramic crown restoration, shorten the clinical impression operation time and crown adjustment time, and will not cause additional adverse effects on periodontal health, which is worthy of clinical application.
