Objective To analyze the factors related to implant marginal bone resorption after implant restoration in elderly patients with severe periodontitis. Methods One hundred and ninety-five elderly patients with severe periodontitis who underwent implant restoration in Hospital of Stomatology of Jilin University from January 2017 to June 2021 were selected， and the implant marginal bone resorption was recorded after 12 months of follow-up. Patients with alveolar ridge resorption height >0.5 mm were included in the resorption group， and the rest were included in the non-resorption group. The general data of the non-resorption group and the resorption group were compared. The influencing factors of implant marginal bone resorption were analyzed by Logistic regression model. Results After 12 months of follow-up， 40.80% of the patients had implant marginal bone resorption. Logistic regression analysis showed that smoking （OR=3.080， 95% CI 1.494-6.349）， diabetes （OR=2.542， 95% CI 1.355-4.769）， missing teeth in the upper jaw （OR=3.951， 95% CI 1.800-8.671）， the angle between the long axis of the implant and the long axis of the crown （OR=2.000， 95% CI 1.066-3.752）， and poor peri-implant hygiene （OR=2.573， 95% CI 1.435-4.614） were risk factors for adverse marginal bone resorption around implants. In contrast， the thickness of the bone quality at the implantation site （OR=0.214， 95% CI 0.086-0.533） was a protective factor， with all P < 0.05. Conclusion Smoking， diabetes， missing teeth in the upper jaw， the angle between the long axis of the implant and the crown， poor peri-implant hygiene， and the bone quality at the implantation site affected the marginal bone resorption around implants in elderly patients. |
