Objective To explore the effect of bone-level implant with platform-switching design on dental aesthetics in patients undergoing single-tooth restoration in the anterior region. Methods A total of 66 patients who received single-tooth restoration in the anterior region at NanjingQixia District Hospital from April 2021 to March 2023 were selected as the research subjects, and they were divided into the control group and the observation group by the random number table method, with 33 patients in each group. The control group was restored with soft tissue-level implant, and the observation group was restored with bone-level implant with platform-switching design. The gingival margin recession, papilla preservation, dental aesthetics, implant loss rate and periodontal health status were compared between the two groups. Results The gingival margin recession of the observation group at 1 and 2 years after restoration was lower than that of the control group (P <0.05).The Jemt scores of the observation group at 1 and 2 years after restoration were higher than those of the control group (P <0.05).The PES scores of the observation group at 1 and 2 years after restoration were higher than those of the control group (P <0.05).The implant loss rate of the observation group was 6.06%, which was lower than 15.15% of the control group (P <0.05).The PPD and BOP of the observation group at 2 years after restoration were better than those of the control group (P <0.05). Conclusion The application of bone-level implant with platform-switching design in patients undergoing single-tooth restoration in the anterior region can better maintain the stability of gingival margin position and the integrity of papilla morphology, obtain a better Pink Esthetic Score, while maintaining a lower implant loss rate and healthier periodontal status. Its aesthetic effect and long-term stability are superior to those of traditional soft tissue-level implant.
