Risk of Dental Implant Failure with Obesity.

This article investigates the association between obesity, defined by body mass index (BMI), and dental implant failure in a retrospective cohort of 6,241 patients receiving 16,921 implants at the Mayo Clinic from 2000 to 2021. The study found no significant correlation between obesity (BMI ≥ 30) and implant failure, while current smoking and male sex were significantly associated with increased risk of failure. Limitations included incomplete periodontal disease data and reliance on BMI as a measure of obesity. The findings suggest that obesity alone may not increase implant failure risk, but smoking cessation and periodontal health remain important considerations in implant treatment planning.
