Objective: To analyze the influence of tooth extraction site preservation techniques on the aesthetic effect of alveolar cavities, the success rate of dental implants, and inflammatory indicators in patients undergoing oral implants. Methods: 70 patients with oral implants who visited the Department of Stomatology of our hospital from August 2023 to August 2025 were selected and grouped by random number table method. The conventional group (n=35) was treated with conventional implant restoration, and the observation group (n=35) was treated with tooth extraction site preservation technology on the basis of the conventional group. The Red Aesthetic Scoring Criteria (PES) scores, alveolar bone changes, success rate of dental implants, gingival sulcus inflammation indicators, and total incidence of complications were compared between the two groups. Results: Compared with the PES score, alveolar bone density, height, width and the success rate of dental implantation in the conventional group after treatment, the observation group had higher scores (P < 0.05). Compared with the conventional group, the total incidence of interleukin-6 (IL-6) in the gingival sulcus, tumor necrosis factor -α (TNF-α) and complications after treatment was lower in the observation group (P < 0.05). Conclusion: The application of tooth extraction site preservation technology in oral implant restoration can effectively improve the aesthetic restoration effect of the alveolar cavity and the success rate of dental implantation, reduce the inflammatory response of the gingival sulcus, and decrease complications, with remarkable effects.
