Objective To explore the application effect of multi-mode oral health education in patients undergoing dental implant surgery. Methods A total of 80 patients (136 teeth) with dental implant surgery admitted to the Department of Stomatology of Qingxin District People's Hospital from January 2020 to December 2022 were selected as the research objects. They were divided into control group (40 patients, 67 teeth) and observation group (40 patients, 69 teeth) by random number table method. The control group received routine health education, and the observation group received multi-modal oral health education. The postoperative cooperation, psychological status, oral care quality and complications were compared between the two groups. Results The rate of not eating within 2 h after operation, the rate of hot compress and cold compress according to the requirements after operation, the rate of not brushing teeth at 24 h after operation, the rate of medication according to the doctor's advice, and the rate of brushing teeth every morning and evening from 2 d after operation in the observation group were higher than those in the control group, and the rate of licking the planting area after operation was lower than that in the control group, the differences were statistically significant (P <0.05). The SAS and SDS scores of the observation group afete nursing were lower than those of the control group, the difference was statistically significant (P <0.05). The oral care quality score of the observation group after nursing was higher than that of the control group, and the difference was statistically significant (P <0.05). The incidence of complications in the observation group was 2.50%, which was lower than 22.50% in the control group, and the difference was statistically significant (P <0.05). Conclusion Compared with routine health education, multi-mode oral health education can keep patients with dental implant surgery in a good state of mind, improve the coordination of postoperative nursing intervention, help improve the quality of care and reduce the incidence of postoperative complications.
