Adults aged 65\u2009years or older with baseline tooth\u2010chart information and no prior hip fracture were included. Functional occlusal support was classified using the Eichner classification, a prosthodontically relevant measure of posterior occlusal support. The primary outcome was incident hip fracture identified from medical claims. Cox proportional hazards models were used with sequential adjustment for demographic characteristics, osteoporosis\u2010related factors, neurologic and vascular comorbidities, and hospitalization history. Additional analyses included piecewise Cox models by follow\u2010up interval and a 1\u2010year landmark analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 3\u2009349\u2009245 participants, lower functional occlusal support was associated with a higher risk of hip fracture. In the fully adjusted model, hazard ratios were 1.21 for Eichner class B and 1.44 for class C, compared with class A. The association varied according to denture\u2010related status, with significant interaction terms for class B and class C. Findings were broadly consistent in time\u2010interval and landmark analyses. Median follow\u2010up was 5.66\u2009years, during which 93\u2009921 hip fractures occurred, corresponding to an overall incidence rate of 5.17 per 1000 person\u2010years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Reduced functional occlusal support was associated with a higher risk of hip fracture in older adults.
