Abstract: PURPOSE: To evaluate the effect of digital guide plate assistance in anterior tooth implant restoration. METHODS: A total of 98 patients who underwent anterior tooth implant restoration from January 2022 to January 2024 were selected and divided into the control group and experimental group by the random number table method, with 49 cases in each group. The control group received conventional implant restoration, while the experimental group was assisted by digital guide plates. The deviation between the actual and designed positions of the implants was compared between the two groups. At the 3rd and 6th months postoperatively, the restorative outcomes were evaluated using the modified United States Public Health Service(USPHS) criteria. At the 6th month postoperatively, the patients' periodontal health status was assessed by measuring probing depth (PD), gingival index (GI), sulcus bleeding index (SBI) and plaque index(PLI). Additionally, the pink esthetic score(PES), as well as occlusal and masticatory functions were evaluated. RESULTS: The deviation between the actual position of the implant in the experimental group and the designed position was significantly less than that in the control group. At the 3rd and 6th months postoperatively, the USPHS score, PD, GI, SBI and PLI in the experimental group were significantly lower than those in the control group, while PES, occlusal and masticatory functions were significantly higher than those in the control group(P<0.05). CONCLUSIONS: Digital guide plate assistance can reduce the positional deviation of anterior tooth implants, improve aesthetics and masticatory function, and reduce periodontal inflammation, providing a reliable clinical treatment plan for precise implant restoration in the anterior tooth.
