Objective To explore the application effect of digital direct impression method in all-ceramic crown restoration. Methods A total of 200 patients with all-ceramic crown restoration admitted to our hospital from April 2021 to April 2022 were selected and divided into control group and observation group according to the random number table method, with 100 patients in each group. The observation group was treated with digital direct impression method, and the control group was treated with indirect impression method. The repair satisfaction, repair effect, model preparation time and tooth wearing time were compared between the two groups. Results The repair satisfaction of the observation group was 97.00%, which was higher than 79.00% of the control group, and the difference was statistically significant (P <0.05). The marginal fitness, surface texture, appearance and color scores of the restorations in the observation group were higher than those in the control group, and the differences were statistically significant (P <0.05). The model preparation time and tooth wearing time in the observation group were lower than those in the control group, and the differences were statistically significant (P <0.05). Conclusion The application of digital direct impression method in all-ceramic crown restoration is effective, which can effectively improve the restoration effect, improve the satisfaction of patients, shorten the time of mold making and tooth wearing, and is worthy of clinical application.
