Objective To analyze the effect of digital dental implant impression in dental implant restoration treatment. Methods A total of 66 patients who received dental implant restoration treatment in Nantong First People's Hospital from January 2022 to December 2024 were selected, and they were divided into the control group and the observation group according to different impression methods, with 33 patients in each group. The control group received traditional dental implant impression, and the observation group received digital dental implant impression. The implant status, restoration effect, quality of life and adverse reaction rate were compared between the two groups. Results The implant distance, angle and vertical displacement of the observation group were lower than those of the control group (P<0.05). There was no statistically significant difference in implant rotation angle between the two groups (P>0.05). The scores of appearance, occlusion, proximal contact and comfort of the observation group after treatment were higher than those of the control group (P<0.05). The scores of all dimensions of quality of life in the observation group after treatment were higher than those in the control group (P <0.05). The incidence of adverse reactions in the observation group (3.03%) was lower than that in the control group (24.24%) (P <0.05). Conclusion Compared with traditional dental implant impression, digital dental implant impression has a better application effect in dental implant restoration treatment. It has smaller errors, which can ensure the restoration effect by optimizing the precision of implant position, help to improve patients' quality of life and reduce the incidence of adverse reactions. It is worthy of clinical application.
