Dental implant surgery increasingly benefits from structured peri-operative and maintenance care that prevents peri-implant disease and improves patient-reported outcomes. This systematic review synthesized randomized, quasi-experimental, and pilot evidence on nursing-led or nursing-delivered interventions for patients undergoing dental implant surgery, including experiential education with health coaching, structured postoperative nursing protocols, telemedicine follow-up, and supportive peri-implant therapy (SPiT) within nursing pathways. In seven original studies, these strategies consistently improved oral hygiene behaviors and clinical parameters such as plaque index, bleeding on probing, and probing depths. Several trials reported additional gains in pain, aesthetics, satisfaction, and adherence; complication signals generally favored structured nursing approaches. Evidence comparing professional maintenance modalities (ultrasonic vs. Er:YAG laser) showed both are effective short-term, with select advantages in bleeding, plaque and comfort that may support adherence. Heterogeneity in intervention content, follow-up duration, and outcome definitions limited pooling. Overall, patient-centric nursing interventions and risk based supportive maintenance appear to enhance peri-implant health and care experience after implant surgery. Future trials should standardize outcome sets, report fidelity, adherence, and evaluate long-term disease recurrence and cost-effectiveness.
