Is Body Mass Index an Independent Risk Factor for Peri-Implantitis?

Is BMI an Independent Risk Factor for Peri-implantitis?Background: Peri-implantitis is a biologic complication of implant therapy that compromises long-term function and esthetics.With obesity rising globally, determining whether body mass index (BMI) independently contributes to peri-implantitis is critical for identifying at-risk patients and improving implant success.Purpose: The purpose of this study was to measure the association between BMI and periimplantitis.
