Risk Factors for Dental Implant Failure: A Strategy for the Analysis of Clustered Failure-time Observations

摘要: This study’s objective was to identify, in a statistically valid and efficient manner, the risk factors associated with dental implant failure. We hypothesize that exist which can be modified by clinicians enhance outcome. A retrospective cohort study design used. Cohort members had ≥ one placed. Risk were classified as demographic, health status, implant-, anatomic-, or prosthetic-specific, reconstructive variables. The outcome variable composed of 677 patients who 2349 implants Based on adjusted multivariate model, failure tobacco use, length, staging, well size, immediate (p ≤ 0.05). In setting correlated survival observations, we recommend adjusting for correlation observations provide results. Three identified factors—tobacco implants, staging—potentially may modified...
