Objective To explore the value of implementing individualized pain nursing+cold compress intervention in swelling and pain management after dental implant surgery. Methods A total of 70 patients who underwent dental implant surgery at China-Japan Friendship Hospital from October 2022 to October 2025 were selected, and they were divided into the control group and the observation group by the random number table method, with 35 patients in each group. The control group received conventional nursing, and the observation group received individualized pain nursing combined with cold compress intervention. The pain intensity, postoperative swelling duration, negative emotions, dental implant function and satisfaction were compared between the two groups. Results After intervention, the score of VAS in the two groups was lower than that before intervention, and that in the observation group was lower than that in the control group (P<0.05). The postoperative swelling duration of the observation group was shorter than that of the control group (P<0.05). After intervention, the scores of SAS and SDS in the two groups were lower than those before intervention, and those in the observation group were lower than those in the control group (P<0.05). The scores of language function, comfort function, masticatory function and ffxation function in the observation group were higher than those in the control group (P<0.05). The satisfaction of the observation group was higher than that of the control group (P<0.05). Conclusion The combined application of individualized pain nursing and cold compress intervention in patients undergoing dental implant surgery can effectively relieve pain, shorten the duration of postoperative swelling, help patients maintain a positive emotional state, improve dental implant function, and enhance patient satisfaction.
