The periodontal indicators, oral health impact degree, oral health self-efficacy, and nursing satisfaction of the two groups before and after the nursing were compared. Results: After intervention, the GI, SBI, PLI, and PD scores in the observation group were lower than those in the control group (P<0.05). The OHIP-14 score in the observation group was lower than that in the control group (P<0.05). The scores for balanced diet, correct brushing, and regular medical visits in the observation group were higher than those in the control group (P<0.05). The nursing satisfaction in the observation group was higher than that in the control group (P<0.05), Conclusion: Regular oral health education combined with oral care can effectively improve the periodontal status of patients with chronic periodontitis after dental implant restoration, improve the oral health-related quality of life and self-efficacy, and enhance nursing satisfaction.
